A universal masterbatch is a pigment or additive concentrate whose carrier is a wax instead of a polymer-specific resin, so one grade can be let down into more than one family of base polymer, usually at 1-5 % of the resin (99:1 to 19:1). That flexibility has a price, because the wax stays in every part; so when does one universal grade replace a shelf of polymer-specific ones, and when does it fail?
Colorants and stabilizers are plastic additives rarely dosed as neat powder: masterbatch is the delivery form for most colorants and for UV stabilizers, antioxidants and other plastic additives.
The 5 main types and both let-down conventions are on the masterbatch hub; this page covers the carrier, its 6 limits, polymer fit, carrier load, testing, rules and producers.
In brief:
- Active content: 40-65 wt% typical, 15-80 wt% in extreme cases
- Let-down: 1-5 % of the base polymer (99:1 to 19:1)
- Polyethylene wax carrier: up to about 10,000 g/mol, melting at 90-110 °C
- Melt viscosity: 3 wt% wax plus 1.0 wt% zinc stearate restored a 60 wt% CaCO3 masterbatch to near-neat viscosity (Radebe and co-workers, 2022)

What Is a Universal Masterbatch?#
A universal masterbatch is a masterbatch whose carrier, normally a wax, is chosen to mix into several base polymers instead of one, so a single grade of colour or additive concentrate serves polyolefin, styrenic and other lines. Other masterbatch types are named for what they carry; this one, also called "multi-purpose masterbatch", is named for its carrier.
What makes a masterbatch carrier "universal"?#
A masterbatch carrier is universal because it is a low-molecular-weight wax that melts at about 90-110 °C, far below the temperatures at which thermoplastics are melt-processed, so it liquefies and spreads before the base polymer has fully melted instead of having to match that polymer's own melt flow. Polyethylene wax, the standard universal carrier, averages up to about 10,000 g/mol (Mhlabeni, Jamiru and Mhike, 2024, Frontiers in Chemical Engineering).
Polymer-specific carriers belong to the base polymer's family instead: EVA or LDPE for polyolefins and nylon, and polystyrene for ABS, SAN and sometimes polycarbonate. Carrier matching by melt index is covered under masterbatch carrier resins.
Is a universal masterbatch a color masterbatch or an additive masterbatch?#
A universal masterbatch can be either, because "universal" names the carrier while "color" or "additive" names the active content: a wax-carried pigment concentrate is a universal color masterbatch, and a wax-carried UV stabilizer or antioxidant concentrate is a universal additive masterbatch.
Colour is the commonest use in search results; pigment choice is covered on color masterbatch.
A wax-carried titanium dioxide concentrate is, by the same logic, a universal white.
Additive grades share the arithmetic: Ampacet's 4 % antioxidant masterbatch at 2.5 % (39:1) gives 1000 ppm in the part. The 14 functional concentrates are compared under additive masterbatch.
What Is a Universal Masterbatch Made Of?#
A universal masterbatch is made of 3 components: a wax carrier, an active content of typically 40-65 wt% pigment, dye or additive, and a dispersing aid such as a metal stearate or a polyglycerol ester. Table T1 lists each component's job and share.
| Component | Job in the pellet | Typical share | Examples | Source |
|---|---|---|---|---|
| 1. Carrier (wax) | Melts first, wets the active content and carries it into the base polymer | The balance: about 35-60 wt% when the active content is 40-65 wt% | Polyethylene wax (CAS 9002-88-4), oxidized polyethylene wax (CAS 68441-17-8), Fischer-Tropsch wax, metallocene polyolefin wax | Struktol, Baerlocher and Clariant data |
| 2. Active content | Gives colour or function to the finished part | 40-65 wt% typical; 15-80 wt% in extreme cases | Organic and inorganic pigments, solvent dyes, carbon black, titanium dioxide, UV stabilizers, antioxidants | General industry definition; Ampacet |
| 3. Dispersing aid | Wets particles, breaks agglomerates, lowers melt viscosity | 1-5 % of a colour masterbatch formulation (Palsgaard Einar 103); 1.0 wt% zinc stearate with 3 wt% wax in a 60 wt% CaCO3 masterbatch | Zinc stearate, polyglycerol esters, micronised and metallocene waxes | Palsgaard; Radebe and co-workers, 2022 |
Typical published values, not a recipe; the carrier share is the arithmetic balance.
Premix and split-feed compounding of the 3 components are explained under how masterbatch is made.
1. The carrier: polyethylene, oxidized PE, Fischer-Tropsch and metallocene waxes#
The carrier of a universal masterbatch is a polymer wax in one of 4 forms: polyethylene wax, oxidized polyethylene wax, Fischer-Tropsch wax or a metallocene polyolefin wax, all of which melt or drop at about 90-131 °C and carry no polymer-family identity of their own. The 4 polymer waxes are listed below.
- Polyethylene wax: CAS 9002-88-4, (C2H4)n; melts at 90-105 °C (Struktol PE(H)-100) or 102-110 °C (Baerlocher PA-L)
- Oxidized polyethylene wax: CAS 68441-17-8; polar groups from oxidation; dropping point 99-108 °C or 131 °C (Struktol PE(O)-600, PE(O)-300)
- Fischer-Tropsch wax: about 200-1,000 g/mol, narrow distribution; melts at 100-105 °C (Baerlocher L-KO)
- Metallocene polyolefin wax: Clariant's Licocene, a dispersion aid and carrier "permitting higher pigment and additive loadings, lower processing temperatures and reduced shear"
Molecular weight sets die build-up (limit 2); all 6 wax types used in plastics are compared on polymer waxes (PE, OPE, Fischer-Tropsch, Montan).
2. The active content: colorants or additives#
A universal masterbatch carries the same 40-65 wt% of colorant or additive as any other masterbatch, with 15-80 wt% at the extremes, and the carrier choice moves that ceiling: Clariant positions its metallocene waxes as carriers that permit higher pigment and additive loadings. No source in our library makes wax-carried grades generally weaker or stronger. The pigments, dyes and effect colorants a universal grade can carry are classified on colorants for plastics.
3. Dispersing aids and metal stearates#
Dispersing aids such as zinc stearate, polyglycerol esters and micronised waxes wet the pigment or filler surface and lower the melt viscosity of the concentrate, and in a wax-carried pellet the carrier itself shares that job. Radebe and co-workers (University of Pretoria, Journal of Polymer Engineering, 2022) showed that 3 wt% wax with 1.0 wt% zinc stearate brought a 60 wt% calcium carbonate LLDPE masterbatch from 3 times the neat melt viscosity back to just above it. Wax, soap and ester dispersants are compared on dispersing agents for plastics and masterbatch.
Palsgaard doses Einar 103 polyglycerol ester at 1-5 % of a colour masterbatch formulation; zinc stearate (CAS 557-05-1), a metal stearate, melts at 130 °C (PubChem).
Universal vs Polymer-Specific Masterbatch: What Is the Difference?#
A universal masterbatch carries its colour or additive in a wax that fits several base polymers, while a polymer-specific masterbatch uses a carrier from the base polymer's own family, such as LDPE or EVA for polyolefins and polystyrene for ABS and SAN, so the universal grade trades melt matching for one-grade flexibility. Table T2 compares the two routes on 8 criteria.
| Criterion | Universal masterbatch | Polymer-specific masterbatch | Source |
|---|---|---|---|
| 1. Carrier | Polymer wax: PE, OPE, Fischer-Tropsch or metallocene polyolefin wax | Resin of the base polymer's family: LDPE or EVA (polyolefins, nylon), PS (ABS, SAN, sometimes PC), MLDPE or LLDPE below MI 20 (pressure-pipe black) | General industry definition; Ampacet |
| 2. Base polymers per grade | More than one family | One family | General industry definition |
| 3. Melt behaviour | Wax melts or drops at about 90-131 °C, ahead of the base polymer | Carrier melt flow matched to the base polymer (melt index) | Struktol, Baerlocher; Ampacet |
| 4. What the carrier leaves in the part | Wax at roughly 35-60 % of the let-down level | A resin of the same polymer family | Calculated from 40-65 wt% active content |
| 5. Lubricating side effect | Wax is an external lubricant in rigid PVC; low-molecular-weight wax can worsen die drool | Minimal when the carrier belongs to the base polymer family | Struktol, Baerlocher; Mhlabeni and co-workers, 2024 |
| 6. Food-contact status of the carrier | PE wax FCM No 549 (no specific SML); OPE FCM No 811 (SML 60 mg/kg) and 21 CFR 177.1620 | The carrier resin's own listing as a polymer | Regulation (EU) No 10/2011; 21 CFR |
| 7. Typical users | Multi-polymer processors, short runs, trial colours | Single-polymer lines, specification-bound parts (pressure pipe) | Editorial grouping |
| 8. Shared by both | 40-65 wt% active content, 1-5 % let-down, pigment-induced shrinkage and colour limits | Same | General industry definition; PMC10298002 |
Row 7 is an editorial grouping, not a market survey.
Where, then, does the universal grade stop working?
What Are the 6 Limits of a Universal Masterbatch?#
A universal masterbatch has 6 limits: its wax carrier stays in the finished part, low-molecular-weight wax can cause die drool and over-lubrication, the colorant must survive the hottest polymer in the range, solvent dyes do not travel into polyolefins, specification-locked parts demand a matched carrier, and unmelted carrier shows up as gels and streaks.
1. The carrier stays in the finished part#
The wax carrier does not leave the melt: at a 2 % (49:1) let-down of a 50 wt% pigment concentrate, for example, the finished part contains 1 wt% pigment and up to 1 wt% wax and dispersant, which is why the base polymer's melt flow and properties are checked after the first universal run. Melt flow rate under ISO 1133 or ASTM D1238 (edition D1238-26) is an empirically defined parameter, so the check compares the polymer with and without the masterbatch.
2. Low-molecular-weight wax can cause die drool and over-lubrication#
Low-molecular-weight waxes are the reason a universal carrier can leave deposits at the die: Mhlabeni, Jamiru and Mhike reported in 2024 that paraffin and Fischer-Tropsch waxes of about 200-1,000 g/mol tend to make die drool worse than polyethylene wax.
In rigid PVC the same wax is an external lubricant: about 1 wt% wax adds about 1.08 phr (calculated) to a pipe compound whose PPI TR-2 (2023) range for PE wax is 0.0-0.3 phr. Internal and external lubrication are explained on processing lubricants for plastics.
3. Colorant heat stability must cover the hottest polymer#
A universal colour masterbatch is only as universal as its least heat-stable colorant: diarylide yellows break down above about 200 °C and weathering-grade titanium dioxide is a poor candidate above 232 °C (450 °F), so every pigment must survive the hottest process in the range. Three published heat limits set the window.
| Colorant | Heat limit | Consequence in a universal grade |
|---|---|---|
| Diarylide yellows (e.g. Pigment Yellow 83) | About 200 °C; breakdown can release 3,3'-dichlorobenzidine | Not for any polymer processed above 200 °C |
| Titanium dioxide, highly treated weathering grade | Poor candidate above 232 °C (450 °F) (Ampacet) | A different white grade for hotter polymers |
| Titanium dioxide, low-treated rutile | A few grades suit extrusion above 274 °C (525 °F) (Ampacet) | Pinking risk with phenolic antioxidants |
Heat-stability ratings are on pigment fastness in plastics: heat stability.
4. Solvent dyes do not travel into polyolefins#
A universal grade coloured with solvent dyes cannot follow its carrier into polyethylene or polypropylene: Lanxess lists its Macrolex solvent dyes for styrenics, PMMA, polycarbonate, PPO, rigid PVC and PET, and polyolefins are not on that list, so a concentrate meant for every line has to use pigments. Which polymers dissolve which dyes is covered under solvent dyes for plastics.
5. Specification-locked parts: pressure-pipe black masterbatch#
Pressure pipe is where a specification overrides universality: a 35 wt% black masterbatch must be let down at 5.7-7.1 % (about 16.5:1 to 13:1) to reach the 2.0-2.5 % carbon black of ISO 4427-1, and Ampacet specifies an MLDPE or LLDPE carrier below melt index 20. At that let-down the carrier is about 3.7-4.6 % of the pipe wall (calculated), a polyethylene rather than a wax; Ampacet's published 5-6.5 % (19:1 to 14:1) gives 1.75-2.28 %, inside the band only at its top. Carbon black grades are on black masterbatch.
6. Unmelted carrier shows up as gels and streaks#
Gels and streaks are the visible failure of a carrier that does not merge with the base polymer: Ampacet names "un-melted resin or un-melted concentrate" as one of the 3 sources of gels in polyethylene film, next to degraded polymer and poor dispersion. Its remedies include tighter screen packs, smaller pellets and carrier changes. All additive-related causes are traced on gels and fisheyes in plastic film.
Which Polymers Can a Universal Masterbatch Be Used In?#
A universal masterbatch fits polyolefins and styrenics most easily, because both take a wax at a 1-5 % let-down without a lubricant penalty, and it needs a trial in PVC, polyamide, polycarbonate and PET, where the wax either lubricates the melt or meets a polymer with its own matched carrier. Table T3 lists the recorded polymer-specific carrier and the first check.
| Polymer | Polymer-specific carrier | Universal (wax) grade | Check first |
|---|---|---|---|
| PE (LDPE, LLDPE, HDPE) | LDPE, LLDPE or EVA; MLDPE or LLDPE below MI 20 for pressure-pipe black | Used; wax and PE are chemically close | Pipe and other specification-bound parts |
| PP | Polyolefin carrier or EVA | Used | Pigment-induced shrinkage: +13.6-22.3 % (transparent phthalocyanine green), +49.5-58.3 % (opaque Cr/Cu-oxide green) at 1-5 wt% masterbatch |
| PS, ABS, SAN | PS (see additives for polystyrene) | Used with checks | Solvent dyes and pigments both possible (Macrolex list) |
| PVC (rigid) | Not recorded in our source library | Trial only | Wax is an external lubricant: about 1 phr at 1 wt% against 0.0-0.3 phr PE wax (PPI) |
| PA (nylon) | EVA or LDPE | Trial | The recorded nylon carrier is already polyolefinic |
| PC | PS in some formulations | Trial | Melt flow rate after let-down |
| PET | Not recorded in our source library | Trial | Solvent dyes listed for PET; nearly all cleared for PET below 0.20 % (Lanxess) |
Carriers as recorded in our source library, not an exhaustive matrix; trials decide.
Polyethylene and polypropylene#
Polyethylene and polypropylene take a universal masterbatch most readily, because a polyolefin wax is chemically the same family as the base polymer; the limits that remain come from the pigment, not the carrier. The full PE package is on additives for polyethylene (PE).
Pipe is the exception (limit 5).
In polypropylene, 1-5 wt% green masterbatch raised flow-direction shrinkage by 13.6-58.3 % in a Europe PMC study (PMC10298002), whatever the carrier. Pigment interactions are covered on additives for polypropylene (PP).
Styrenics: PS, ABS and SAN#
Styrenics such as polystyrene, ABS and SAN are the second natural home of a universal masterbatch, and unlike polyolefins they accept solvent dyes, which Lanxess lists for PS, SAN and ABS. The styrenic package is on additives for ABS, SAN and ASA.
PVC: when the wax carrier becomes a lubricant#
In rigid PVC the wax carrier of a universal masterbatch is also an external lubricant, and about 1 wt% of it adds about 1.08 phr (calculated) to a compound whose PPI TR-2 (2023) example carries only 0.15 phr of PE wax. That 108.03-phr pipe compound uses paraffin 1.20, PE wax 0.15 and calcium stearate 0.45 phr as lubricants. Grades and FCM 549 status are on polyethylene wax.
Struktol doses oxidized PE wax at 0.1-0.2 phr in rigid pipe.
The fix is a rebalanced lubricant package or a PVC-compatible concentrate, as shown under lubricants for PVC compounding.
Engineering plastics: PA, PC and PET#
Engineering plastics such as polyamide, polycarbonate and PET are where a universal grade needs the most proof, because the carriers recorded for them are already a compromise: EVA or LDPE for nylon, and polystyrene, only sometimes, for polycarbonate. The polyamide package is on additives for nylon (polyamide).
In polycarbonate, compare melt flow with and without the concentrate (additives for polycarbonate and PC/ABS).
In PET, Lanxess reports nearly all Macrolex dyes cleared for PET below 0.20 % under the FDA rules it cites. Bottle colorants are on additives for PET resin.
How Much Universal Masterbatch Do You Add? Let-Down Ratio and Carrier Load#
A universal masterbatch is added at the same 1-5 % of the base polymer as any masterbatch, written as a let-down ratio of 99:1 to 19:1, but with a universal grade the number to watch is the carrier load: the share of wax the let-down leaves in the part next to the colour or additive. Coloured pipe masterbatch runs at 2-4 % (49:1 to 24:1).
Active in part (wt%) = active content of masterbatch (wt%) x let-down (%) / 100
Carrier in part (wt%) = (100 - active content - dispersant) (wt%) x let-down (%) / 100
Worked example: pigment and wax in the finished part#
A 50 wt% universal colour masterbatch let down at 2 % (49:1) puts 1.0 wt% pigment and about 0.94 wt% wax into the finished part, so the carrier is nearly half of everything the concentrate adds. The 4 steps are listed below.
- Read the active content (example: 50 wt% pigment).
- Subtract the dispersing aid (example: 3 wt%) to get the carrier (47 wt%).
- Multiply each share by the let-down (example: 2 %, 49:1).
- Compare the result with the part's limits (pigment 1.0, wax 0.94, dispersant 0.06 wt%).
How Do You Choose Between a Universal and a Polymer-Specific Masterbatch? 5 Checks#
Choose between a universal and a polymer-specific masterbatch with 5 checks: count the base polymers, check the specification, compare the colorant heat limit with the hottest process, calculate the carrier load, and confirm the food-contact route in every polymer. The 5 checks are listed below.
- Count the base polymer families: one points to a polymer-specific grade.
- Check whether a standard or customer names the carrier, as for pipe black.
- Compare pigment heat limits (about 200 °C for diarylide yellows) with the hottest process, and keep solvent dyes out of PE and PP.
- Calculate the carrier load and, for rigid PVC, the extra lubricant in phr.
- Confirm the food-contact route of carrier and colorants in each polymer.
A single-polymer, high-volume line should prefer a polymer-specific grade, since one-grade flexibility brings it nothing.
How Do You Test a Universal Masterbatch in a New Polymer?#
A universal masterbatch is qualified in each new polymer with 3 tests: a melt flow rate comparison under ISO 1133 or ASTM D1238, a dispersion rating, and a colour measurement under ASTM D2244, because the same pellet can pass in polyethylene and fail in another polymer. Table T4 adds a shrinkage check.
| Test | Standard | What it shows for a universal grade |
|---|---|---|
| Melt flow rate | ISO 1133 / ASTM D1238 (edition D1238-26) | Whether the wax carrier has shifted the base polymer's flow; compare with and without masterbatch |
| Dispersion | Microdispersion rating 1-5 (1 best) on about 1.5 mil (38 µm) PE film, per lot (Ampacet); ISO 18553 grade 3 or better for PE pipe; see dispersion testing of pigments and masterbatch | Whether the carrier melted in and wetted the pigment |
| Colour | ASTM D2244 (edition D2244-25) in CIELAB, CMC, CIE94, DIN99o or CIEDE2000 units; see color measurement and matching of plastics | Whether the colour matches in each polymer; metamerism checked under 2 illuminants |
| Shrinkage | Part measurement in flow and cross-flow direction | Pigment-induced change in moulded PP (+13.6-58.3 % in the PMC10298002 study) |
Our sources set no pass or fail threshold for a carrier-induced shift in melt flow; test conditions are on melt flow rate (MFR).
Which Food-Contact and Chemical Rules Apply to a Universal Masterbatch?#
Food-contact and chemical rules apply to every substance in a universal masterbatch, carrier included, and they are checked in the finished part, so one grade has to be compliant separately for each polymer and each use it is sold into.
EU: Regulation (EU) No 10/2011, Annex II metals and REACH Annex XVII entry 23#
In the EU, the wax carriers of a universal masterbatch are themselves authorised plastics additives: polyethylene wax is FCM No 549 with no specific migration limit, and oxidized polyethylene wax is FCM No 811 with an SML of 60 mg/kg under Regulation (EU) No 10/2011. The 3 carrier waxes compare as follows.
| Carrier wax | CAS | EU: Regulation (EU) No 10/2011 | US: 21 CFR |
|---|---|---|---|
| Polyethylene wax | 9002-88-4 | FCM No 549 (Ref 80000), additive use, no specific SML | No 21 CFR entry recorded in our source library |
| Oxidized polyethylene wax | 68441-17-8 | FCM No 811 (Ref 80077), SML 60 mg/kg | 21 CFR 177.1620 (polyethylene, oxidized; Mn ≥ 1,200) |
| Fischer-Tropsch wax | Not yet verified | Refined waxes from synthetic hydrocarbon feedstocks, FCM No 93/94 (see paraffin wax) | 21 CFR 178.3720 (synthetic petroleum wax) |
The 10 mg/dm² overall migration limit covers all migrants; FCM numbers are explained on EU 10/2011.
Colorants are not on the Union list (Council of Europe Resolution AP(89)1 and national rules apply), and carbon black (FCM 411) is capped at 2.5 % w/w in the polymer: a 40 wt% black let down at 7 % already gives 2.8 wt% (calculated).
Annex II (consolidated version of 14 July 2026) limits metal migration to aluminium 1, barium 1, cobalt 0.05, copper 5, iron 48, lithium 0.6, manganese 0.6, zinc 5, nickel 0.02 and antimony 0.04 mg/kg food, with arsenic, cadmium, chromium, lead and mercury not detectable.
REACH Annex XVII entry 23, as amended by Regulation (EU) No 494/2011 from 10 December 2011, keeps cadmium below 0.01 % by weight in listed plastics, a list that includes "LDPE except for coloured masterbatch"; that wording is not a general masterbatch exemption. Entry 23 is set out under REACH Annex XVII restrictions.
US: 21 CFR 178.3297 and why "FDA approved" is the wrong claim#
In the US, each colorant in a universal masterbatch needs its own route under 21 CFR 178.3297, the colorants-for-polymers section, and each carrier wax its own section, such as 21 CFR 177.1620 for oxidized polyethylene, so an unreferenced "FDA approved" claim gives a buyer nothing to check. Section 178.3297 caps high-purity furnace black at 2.5 % of the polymer (PAH ≤ 0.5 ppm, benzo[a]pyrene ≤ 5.0 ppb), and each listed colorant is on 21 CFR 178.3297.
Ask for the section per substance, the conditions of use and any food contact notification (FCN) with its notifier, as an FCN covers only its notifier; see FDA food contact rules for plastic additives.
Who Makes Universal Masterbatch?#
Universal masterbatch comes from masterbatch producers such as Ampacet and Avient, built on carrier waxes from Clariant, Struktol, Baerlocher, Solstice Advanced Materials and Sasol. Buyers should ask for the carrier identity and its FCM or CFR status per polymer. Plants and brand lines are in the directory of masterbatch manufacturers. Table T5 separates the 2 roles.
| Company | Role for universal masterbatch | What our source library records |
|---|---|---|
| Ampacet | Masterbatch producer | Describes itself as the global masterbatch leader |
| Avient | Masterbatch producer | Acquired Clariant Masterbatches in 2020 (as PolyOne, about USD 1.6 bn), then Magna Colours (2021) and DSM Protective Materials (2022) |
| Clariant | Carrier and dispersion waxes | Licocene metallocene waxes, Ceridust micronised waxes |
| Struktol | PE and oxidized PE waxes | PE(H)-100; PE(O)-300 and PE(O)-600 |
| Baerlocher | PE wax and synthetic paraffin | Baerolub PA-L; L-KO |
| Solstice Advanced Materials | Polyethylene waxes | A-C brand, spun off from Honeywell in 2025 |
| Sasol | Fischer-Tropsch wax | Main producer of Fischer-Tropsch wax |
─── The sections below cover alternatives and related questions outside the carrier choice above. ───
What Are the Alternatives to a Universal Masterbatch?#
The alternatives to a universal masterbatch are a polymer-specific masterbatch, liquid color, a precolored compound and dry color, and each one removes the wax carrier from the part in a different way. Opaque whites, which face the same carrier choice, are covered on white masterbatch.
Liquid color concentrates#
Liquid color replaces the wax carrier with a liquid vehicle dosed by a peristaltic pump, which gives highly accurate dosing and quick colour changes. See liquid color concentrates.
Precolored compound and dry color#
A precolored compound puts the colour into the full resin at the compounder, so no carrier is added at the machine, while dry color skips compounding altogether at the cost of weaker dispersion and dust. Precoloring is explained under plastic compounding.
What is a master batch?#
A master batch (masterbatch) is a concentrated mixture of pigments and/or additives blended and extruded together in a carrier matrix and let down into natural resin, usually at 1-5 %. The 5 types are on masterbatch types and composition.
What is filler master batch?#
A filler master batch is a highly loaded calcium carbonate or talc concentrate in a polyethylene or polypropylene carrier, a polymer-specific product rather than a universal one. Calcium carbonate content and let-down are on filler masterbatch.
Is "universal masterbatch" a product type or a company name?#
"Universal masterbatch" is a product type, a concentrate on a carrier that suits several polymers, and the same words also appear in company and brand names, so search results mix product pages with company listings.
Are universal paint tinters the same as universal masterbatch?#
No: universal tinters colour paints and coatings, which are outside the scope of this site, while a universal masterbatch is a solid concentrate let down into molten plastic.
