Flame Retardant Manufacturers and Suppliers for Plastics: 14 Companies by Chemistry and Region

Fourteen companies supply the flame retardants used in plastics today, split across four chemistry groups: brominated and chlorinated, phosphorus and nitrogen based, mineral (ATH and MDH), and the synergists that make the other three work harder. A buyer who starts from a company name usually ends up back at chemistry, because the flame retardant a compound needs depends on the polymer, the UL 94 rating the part must pass and the market it ships to, not on which supplier answers the phone first. This directory maps company to chemistry to application, states which class each company is verified to manufacture, and sets out the checks a buyer runs before requesting a quote.

The 14 companies profiled here range from Albemarle and ICL Industrial Products, which built their businesses on brominated chemistry, to Huber Advanced Materials and Nabaltec, which supply the mineral fillers that now account for the largest share of flame retardant volume by weight. Which of them a buyer contacts depends less on brand recognition than on one question: does the destination market and the end application call for a halogenated system, a phosphorus or nitrogen system, or a mineral filler system, and at what loading level does that system reach the required rating. The sections below answer that question chemistry by chemistry, list the 14 manufacturers with their verified brand lines, and close with the regulatory checks that decide which class stays available where.

What Does a Flame Retardant Manufacturer Actually Sell?#

A flame retardant manufacturer sells a chemical that interrupts combustion, either by scavenging radicals in the gas phase, by forming a protective char in the condensed phase, or by releasing water to cool the polymer and dilute flammable gases. That chemistry reaches a compounder in one of four forms: a halogenated flame retardant (brominated or chlorinated), a phosphorus or nitrogen based flame retardant, a mineral filler such as aluminium trihydrate (ATH) or magnesium hydroxide (MDH), or a synergist that boosts one of the other three. Plastic additives cover 43 families in total, and flame retardants are the single largest family by search volume in this reference, because no plastic used in construction, transportation or electrical equipment ships without one.

The choice between these forms is not cosmetic. A brominated system reaches UL 94 V-0 at bromine loadings under 15 wt%, while a mineral filler needs 160 to 180 phr (about 61.5 wt% at 160 phr) to do the same job in a cable compound, according to Huber Advanced Materials' HFFR reference formulation. That loading difference changes the compound's mechanical properties, its density and its cost, which is why the chemistry decision comes before the supplier decision.

Halogenated, phosphorus, nitrogen or mineral chemistry?#

Four chemistry families cover almost every flame retardant sold into plastics today, each with a distinct mechanism and a distinct supplier base. Brominated flame retardants, including decabromodiphenyl ethane (Saytex 8010, Albemarle) and brominated polystyrene (Saytex HP-3010, Albemarle), work mainly in the gas phase and reach UL 94 V-0 in HIPS and ABS at bromine loadings around 10.7 wt% combined with 5 wt% antimony trioxide, based on Albemarle's own Saytex 8010 data. Phosphorus based flame retardants, such as aluminium diethylphosphinate (AlPi, sold as Exolit OP by Clariant), work mainly in the condensed phase, forming a char layer, and reach V-0 in glass-filled polyamide at 15 to 20 wt% loading. Nitrogen based flame retardants, chiefly melamine derivatives sold by BASF (Melapur) and Italmatch Chemicals (Melagard), release non-flammable gas and dilute the flame; melamine itself carries an EU food-contact specific migration limit of 2.5 mg/kg under Regulation (EU) No 1282/2011. Mineral flame retardants, aluminium trihydrate and magnesium hydroxide, release water endothermically starting at about 200 degrees Celsius for ATH and about 320 degrees Celsius for MDH, and they dominate halogen-free cable compounds by tonnage even though they need the highest loading of the four families.

Each family answers a different application constraint, which is the reason the market supports 14 separate manufacturers rather than one dominant supplier. A compounder building a smoke-sensitive low-voltage cable reaches first for mineral chemistry from Huber or Nabaltec; a compounder building a thin-wall connector reaches first for phosphinate chemistry from Clariant; and a compounder shipping HIPS appliance housings to a market with no halogen restriction still reaches for brominated chemistry from Albemarle or ICL.

Primary flame retardant or synergist?#

A primary flame retardant works alone to reach a UL 94 rating, while a synergist only raises the efficiency of a primary system and is never sold as a standalone flame retardant. Antimony trioxide is the most common synergist for brominated systems and accounts for 39% of US antimony end use in 2024, with the United States importing about 39,000 tonnes of antimony oxide in 2025, 66% of it sourced from China between 2021 and 2024. Zinc borate (Firebrake ZB, U.S. Borax) and zinc stannate (Flamtard S, William Blythe) serve the same synergist role in PVC and halogen-free systems, releasing water above 290 degrees Celsius in the case of zinc borate and adding smoke suppression rather than flame retardancy on their own.

This distinction changes the supplier list a buyer needs. A formulation built on flame retardants for plastics almost always needs two purchase orders, one for the primary chemistry and one for its synergist, and the 14 companies in this directory split cleanly between the two roles: 11 sell primary flame retardants and 3 sell synergists or smoke suppressants only.

Flame Retardant Manufacturers: The Full Directory#

The 14 manufacturers below fall into 4 groups: brominated and chlorinated flame retardant specialists, phosphorus and nitrogen based flame retardant producers, mineral flame retardant (ATH and MDH) producers, and flame retardant synergist and smoke suppressant producers.

Table 1. Flame retardant manufacturer directory. Headquarters cells are left blank where our source library holds no verified location; an empty cell means the value is not yet confirmed against a primary or named source, not that it does not exist.

1. Brominated and chlorinated flame retardant specialists (3)#

Albemarle, ICL Industrial Products and OxyChem built their flame retardant businesses on halogen chemistry, and each still supplies the grades used where no halogen restriction applies. Albemarle sells Saytex 8010 (decabromodiphenyl ethane) and the Saytex HP series of brominated polystyrenes, and reports that 10.7 wt% bromine with 5 wt% antimony trioxide reaches UL 94 V-0 at 0.8 mm in HIPS. ICL Industrial Products, headquartered in Israel, sells 5 distinct brominated and phosphate ester grades (FR-122P, FR-245, FR-370, FR-1025 and Fyrol PCF) for polyolefins, polystyrenics and PVC. OxyChem is the sole manufacturer named in our source library for Dechlorane Plus, a chlorinated flame retardant now listed on the SVHC Candidate List since 15 January 2018 for very persistent, very bioaccumulative (vPvB) properties and added to Stockholm Convention Annex A at COP-11 in 2023.

2. Phosphorus and nitrogen based flame retardant producers (5)#

Clariant, Lanxess, BASF, Adeka and Italmatch Chemicals cover the phosphorus and nitrogen chemistry that has grown fastest as brominated systems have lost ground in Europe. Clariant's Exolit OP phosphinate grades reach UL 94 V-0 at about 15 wt% in unreinforced PA6T/66 and its Exolit AP ammonium polyphosphate grades serve intumescent polyolefin systems. Lanxess sells organophosphate esters (Levagard, Reofos) alongside the Emerald Innovation brominated polymeric line acquired with Chemtura in a deal announced 25 September 2016 and completed 21 April 2017. BASF's Melapur melamine derivatives and Italmatch's Melagard melamine cyanurate both serve unfilled polyamide, and Italmatch additionally sells Masteret encapsulated red phosphorus masterbatches. Adeka's Adeka Stab FP-2100JC and FP-2500S blends are piperazine phosphate systems built for polyolefins.

3. Mineral flame retardant (ATH and MDH) producers (3)#

Huber Advanced Materials, Nabaltec and Kyowa Chemical supply the mineral fillers that make up the largest tonnage share of the flame retardant market despite needing the highest loading. Huber, based in Atlanta and privately held since its founding in 1883, sells Martinal aluminium trihydrate, Magnifin magnesium hydroxide, and the Micral and Hydral product lines; Huber acquired the Martinswerk ATH and MDH business from Albemarle in a transaction completed 1 February 2016. Nabaltec sells Apyral aluminium trihydrate and Actilox boehmite (aluminium oxyhydroxide). Kyowa Chemical sells magnesium hydroxide under the Kisuma brand, positioned as an alternative to Huber's Magnifin in the same halogen-free cable compounds.

4. Flame retardant synergist and smoke suppressant producers (3)#

U.S. Borax, William Blythe and LKAB Minerals sell products that are never used alone: each raises the efficiency of a primary flame retardant or suppresses the smoke a fire produces. U.S. Borax, owned by Rio Tinto, sells Firebrake ZB zinc borate, which releases water above 290 degrees Celsius and is not on the SVHC Candidate List, though suppliers self-classify it Repr. 2 H361d because no harmonised CLP entry has been identified. William Blythe sells Flamtard H (zinc hydroxystannate) and Flamtard S (zinc stannate), both tin-based smoke suppressants used mainly in PVC; Flamtard H is reported at 3 to 5 phr in research formulations. LKAB Minerals sells UltraCarb, a huntite-hydromagnesite blend that releases water at about 220 degrees Celsius and carbon dioxide at about 330 degrees Celsius in low-smoke halogen-free cable compounds.

Who Supplies Which Flame Retardant Chemistry?#

A buyer who starts from the chemistry rather than the company name finds the producer list below organised by the 7 flame retardant classes our source library verifies. Halogenated systems still hold the largest single share of the market by value, but phosphorus, nitrogen and mineral chemistry together outweigh them, which is why this directory lists more phosphorus and mineral specialists than brominated ones.

Table 2. Flame retardant chemistry class to producer.

ECHA's Plastics Additives Initiative, which maps substances registered above 100 tonnes a year in the EU, counts 39 flame retardant substances in that registered set, ranking behind only pigments (127), the unclassified "other function" group (74) and plasticisers (66) among the functions it tracks.

How Do You Choose a Flame Retardant Supplier? 7 Checks#

Choosing a flame retardant supplier takes 7 checks, and the first one is not about the company at all: the destination market decides which chemistry class is still legally available before any supplier gets contacted. The 7 checks below run in the order a buyer should apply them.

1. Confirm the destination market's restriction status for the chemistry class under consideration, since decaBDE, HBCD, TBBPA, TCEP and Dechlorane Plus each carry Stockholm Convention and REACH restrictions that vary by region and by substance.
2. Identify the UL 94 rating or LOI value the finished part must reach, since a V-0 rating at 0.8 mm demands a different loading than a V-2 rating at 3.2 mm.
3. Match the chemistry family to the polymer, because phosphinates work in engineering polyamides where mineral fillers cannot reach the required loading without destroying mechanical properties.
4. Check the required dosage range against the compound's other performance targets, since mineral fillers at 160 phr change density and impact strength in ways a 15 wt% phosphinate system does not.
5. Verify food-contact status under Regulation (EU) No 10/2011 if the part touches food, since melamine carries a specific migration limit of 2.5 mg/kg under that regulation and not every flame retardant chemistry carries a listed limit.
6. Ask whether a synergist is needed, since brominated and zinc-based mineral systems both depend on antimony trioxide or zinc borate to reach their rated performance.
7. Request test data, specifically UL 94 classification, limiting oxygen index and, for electrical parts, glow-wire ignition temperature (GWIT) and comparative tracking index (CTI), rather than accepting a supplier's rating claim without documentation.

How to check a flame retardant's regulatory status#

A flame retardant's regulatory status is checked per substance and per destination market, not per company, because the same manufacturer can sell one grade that is fully compliant and another that is restricted. DecaBDE (CAS 1163-19-5) has been an SVHC since 19 December 2012 for PBT and vPvB properties, was added to Stockholm Convention Annex A at COP-8 in 2017, and now carries an EU POPs unintentional trace contaminant limit of 10 mg/kg for the sum of tetra- to decaBDE congeners under Delegated Regulation (EU) 2025/1482, replacing the earlier 500 mg/kg figure. HBCD (CAS 25637-99-4) has carried an SVHC Candidate List entry since 28 October 2008 and an Annex XIV sunset date of 21 August 2015. TBBPA (CAS 79-94-7) became an SVHC on 17 January 2023 for carcinogenicity, and its harmonised Carc. 1B classification under CLP applies from 1 September 2025 under the 21st Adaptation to Technical Progress. TCEP (CAS 115-96-8) has been an SVHC since 13 January 2010 with an Annex XIV sunset date of 21 August 2015, while TCPP and TDCPP, in contrast, carry no SVHC listing and no Annex XVII restriction as of this review, though the 2018 childcare-article restriction work on that pair remains on hold.

Beyond substance-specific SVHC status, the US TSCA revised decaBDE and PIP (3:1) rule, published 19 November 2024 and effective 21 January 2025, sets a 0.1 wt% unintentional-presence threshold for decaBDE and prohibits distribution of most PIP (3:1) containing articles after 31 October 2026, with motor-vehicle replacement parts exempted until the end of service life or 2036. A buyer checks these dates against the specific grade in question, since exemptions and phase-out schedules differ by substance and by use, and cross-checks the substance against the wider REACH Annex XVII restriction list before ordering a first sample batch.

Which UL 94 rating and LOI value to ask for#

A UL 94 rating states how a plastic specimen behaves when a flame is applied and removed, and the test defines exact numeric pass criteria rather than a general fire-safety claim. A V-0 rating requires a single specimen's afterflame time of 10 seconds or less, a combined afterflame time of 50 seconds or less across 10 applications on 5 specimens, an afterglow time of 30 seconds or less, and no flaming drips that ignite a cotton indicator below the specimen. A V-1 or V-2 rating allows longer single afterflame times up to 30 seconds and combined times up to 250 seconds, and V-2 permits flaming drips that ignite the cotton indicator where V-0 and V-1 do not. The horizontal-burn HB rating, used for thin sections under 3 mm, sets a maximum burn rate of 76 mm per minute, and the automotive FMVSS 302 standard sets a maximum burn rate of 102 mm per minute.

Limiting oxygen index (LOI) measures the minimum oxygen concentration that sustains combustion, and suppliers report it alongside UL 94 data to show margin above the rating. Clariant's Exolit OP 1312 blend, used at 15 to 20 wt% in glass-filled PA6 and PA66, reaches UL 94 V-0 at thicknesses from 0.4 to 3.2 mm together with a glow-wire ignition temperature of 775 degrees Celsius, a glow-wire flammability index of 960 degrees Celsius and a comparative tracking index of 600 V, all figures from the supplier's own technical data. A buyer should ask for UL 94 classification and limiting oxygen index together with glow-wire and tracking-index data for any part with electrical function, since UL 94 alone does not predict ignition resistance under a glowing element.

Which Flame Retardant System Does Your Application Need?#

The application decides the flame retardant chemistry before any supplier gets contacted, since a cable compound, an appliance housing and an engineering-plastic connector each demand a different loading and a different test standard. The table below lists the system verified in our source library for 6 common applications.

Table 3. Flame retardant application to system.

Where Are Flame Retardant Manufacturers Located?#

Flame retardant supply concentrates in 3 regions: Europe, North America and a smaller cluster spanning Israel and East Asia, and the chemistry a region specialises in follows its regulatory history. Europe's mineral and phosphorus specialists grew as the region restricted brominated chemistry earliest; North America still supports 2 of the largest brominated flame retardant producers; and the Israel-Asia cluster combines ICL's brominated portfolio with Adeka's phosphorus chemistry from Japan.

Table 4. Flame retardant manufacturers by region.

Flame retardant manufacturers in Europe and North America#

Europe's flame retardant producers cluster around 4 named headquarters: Clariant in Muttenz, Switzerland, Lanxess in Cologne, Germany, BASF in Ludwigshafen, Germany, and Italmatch Chemicals, whose exact headquarters is not confirmed in our source library. North America's cluster centres on Huber Advanced Materials in Atlanta, which has operated as a private, family-controlled company since its founding in 1883 and which absorbed Albemarle's Martinswerk ATH and MDH business in a transaction completed 1 February 2016. A buyer sourcing in North America who also needs a lead outside this directory can start from the plastic additive supplier finder rather than a single company's own product pages.

Flame retardant manufacturers in Israel and Asia#

ICL Industrial Products, headquartered in Israel, is the only company in this directory that manufactures both brominated flame retardants and organophosphate esters under one roof, giving it the broadest single-company chemistry range of the 14 profiled. Adeka, headquartered in Tokyo, supplies piperazine phosphate flame retardants under the Adeka Stab FP brand, and Kyowa Chemical supplies magnesium hydroxide under the Kisuma brand as an alternative to the Western MDH producers. Buyers sourcing flame retardants for compounds manufactured in plastic additive manufacturers in India most often import from this Israel-Asia cluster or from the European producers above, since no flame retardant manufacturer with a verified Indian headquarters appears in our source library.

What Do Flame Retardants Cost?#

Flame retardant cost tracks 2 variables more closely than brand: the raw-material index behind the chemistry class and the loading level the application demands. Antimony trioxide, the synergist behind most brominated systems, traded at USD 25 per pound in 2025, peaking at USD 27.50 in June 2025 and falling to USD 20.30 in November 2025, and the United States imported about 39,000 tonnes of antimony oxide in 2025, with 66% sourced from China across 2021 to 2024. That price volatility flows directly into brominated system cost, since brominated flame retardants depend on antimony trioxide as their standard synergist.

Loading level changes cost in the opposite direction from raw-material price: a mineral filler system needs 160 to 180 phr to match the performance a brominated system reaches at under 15 wt%, so a mineral system's per-kilogram price can be lower while its cost per finished part is higher once the added weight and the extra compounding capacity are counted. Our source library holds no verified per-kilogram price for any named flame retardant grade, so a buyer comparing quotes should request pricing on the same basis (per phr delivered, not per kilogram of raw material) before comparing 2 suppliers' numbers directly.

How Do You Request a Flame Retardant Quote?#

Requesting a flame retardant quote starts with the 7 checks above, not with a company's contact form, because a supplier cannot price a grade correctly without the application, the target UL 94 rating and the destination market. Buyers who have completed those checks can submit one request to multiple manufacturers through the supplier finder for plastic additives, which routes a single specification to the relevant suppliers in this directory rather than requiring 14 separate emails.

A complete quote request states the polymer, the wall thickness the part must pass UL 94 testing at, the required rating (V-0, V-1, V-2 or HB), the destination market, and whether the part has food-contact or electrical-safety requirements. Suppliers who receive an incomplete request typically respond with a generic product data sheet rather than a dosage recommendation, which costs a buyer a second round trip before formulation work can start.

Flame retardants for plastics sit inside a wider chemical family used across textiles, coatings and building insulation, and the plastics-only manufacturers profiled above supply only part of a market whose overall size is set out below.

How Big Is the Flame Retardant Market?#

The global flame retardant chemicals market is valued at USD 8.1 to 9.3 billion in 2025, according to MarketsandMarkets, with global consumption exceeding 2 million tonnes as of 2013 and Asia-Pacific accounting for 41% of demand as of 2010, based on figures compiled from public market data. Brominated flame retardants alone reached a sales volume of about 390,000 tonnes in 2011, roughly 19.7% of the flame retardant market by that measure, though the share has fallen since as mineral and phosphorus chemistry has grown.

Table 5. Flame retardant market figures.

Why brominated flame retardants lost market share in the EU#

Brominated flame retardants lost market share in the EU because a sequence of REACH and Ecodesign restrictions removed specific substances from the market faster than replacement chemistry could substitute at equal cost. DecaBDE's SVHC listing on 19 December 2012, followed by its Stockholm Convention Annex A listing at COP-8 in 2017 and the tightened POPs limit under Delegated Regulation (EU) 2025/1482, removed the highest-volume brominated grade from new formulations. The Ecodesign Regulation (EU) 2019/2021 banned halogenated flame retardants outright in the enclosures and stands of electronic displays from 1 March 2021, pushing that application entirely to phosphorus and mineral chemistry. Most recently, DBDPE (CAS 84852-53-9) became an SVHC on 5 November 2025 for very persistent, very bioaccumulative properties, and the European Commission mandated a restriction dossier covering non-polymeric aromatic brominated flame retardants on 11 November 2025, with a call for evidence running from 21 January to 18 March 2026.

What are the different types of flame retardants?#

The 4 main types of flame retardants used in plastics are halogenated (brominated and chlorinated), phosphorus based, nitrogen based and mineral, each named for the element or mechanism that interrupts combustion. Halogenated types release flame-inhibiting radicals in the gas phase and include decabromodiphenyl ethane, brominated polystyrene and Dechlorane Plus. Phosphorus types, including aluminium diethylphosphinate and ammonium polyphosphate, form a protective char in the condensed phase. Nitrogen types, mainly melamine and its derivatives, release non-flammable gas that dilutes the flame. Mineral types, aluminium trihydrate and magnesium hydroxide, release water endothermically and dilute combustible gases with steam, and they require the highest loading of the 4 types to reach an equivalent UL 94 rating.

What REACH and POPs mean for a flame retardant buyer#

REACH and the EU POPs Regulation (EU) 2019/1021 together decide which flame retardant chemistry a buyer may still specify for a part sold into the EU, and the two instruments work on different timelines. REACH restrictions and SVHC listings apply to individual substances immediately on their entry-into-force date, as with the Annex XVII entry 51 restriction on 4 ortho-phthalates at 0.1% since 7 July 2020, while POPs in plastics restrictions under Regulation (EU) 2019/1021 typically carry a transitional unintentional trace contaminant limit that steps down in stages, as with decaBDE's move from 500 mg/kg to 10 mg/kg under Delegated Regulation (EU) 2025/1482. A buyer who tracks only the SVHC Candidate List misses the POPs timeline, and a buyer who tracks only POPs misses substances still in REACH restriction preparation, such as DBDPE, which is an SVHC but not yet restricted as of this review. RoHS adds a third, narrower layer specific to electrical and electronic equipment, limiting polybrominated diphenyl ethers to 0.1% in homogeneous materials, and a proposed RoHS addition of TBBPA and medium-chain chlorinated paraffins (MCCP) was dropped from the regulation in 2024.
