SUNCHEM supplies halogenated, phosphorus-based, and mineral flame retardants — TBBPA, DOPO, APP, ATH, and more — for plastics, textiles, electronics, and construction material applications worldwide.
SUNCHEM's flame retardant portfolio covers three key chemistries: halogenated (brominated), phosphorus-based, and mineral/inorganic — each suited to specific polymer systems, processing conditions, and regulatory frameworks including UL-94, IEC 60332, EN 13501, and RoHS.
With products spanning electronics (PCBs, connectors), construction (insulation panels, cables), automotive, and textile applications, SUNCHEM provides reliable supply, consistent quality, and full export documentation for global markets.
Three FR chemistries, consistent quality, and full regulatory documentation for global compliance.
TBBPA and Decabromodiphenyl Ethane (DBDPE) — high-efficiency brominated flame retardants for epoxy resins, ABS, HIPS, and PC/ABS blends. Excellent thermal stability and compatibility with engineering polymer systems.
BDP, RDP, APP, Melamine Cyanurate, and DOPO — halogen-free phosphorus and nitrogen flame retardants for PU foams, polyamides, polycarbonate, epoxy systems, and intumescent coatings. RoHS and REACH compliant options.
Aluminum Hydroxide (ATH) and Magnesium Hydroxide — eco-friendly, halogen-free mineral flame retardants with smoke suppression properties for wire & cable, rubber, and thermoset applications requiring low smoke toxicity.
Three core chemistry types serving diverse polymer and substrate applications.
TBBPA (CAS 79-94-7) for reactive use in epoxy laminates (FR-4 PCBs). Decabromodiphenyl Ethane (DBDPE, CAS 84852-53-9) as an additive FR for ABS, HIPS, polypropylene. High efficiency, low loading requirements.
APP, BDP, RDP for halogen-free formulations. DOPO for reactive phosphorus in epoxy. Melamine Cyanurate for nylon (PA6/PA66). All RoHS-compliant, suitable for EU REACH-registered supply chains.
ATH (Aluminum Hydroxide, CAS 21645-51-2) and Magnesium Hydroxide (CAS 1309-42-8) — endothermic, smoke-suppressing, halogen-free. Ideal for wire & cable, EVA foils, rubber profiles, and construction composites.

TBBPA (Tetrabromobisphenol A, CAS 79-94-7) is the world's highest-volume brominated flame retardant. It is used reactively in epoxy resins for FR-4 printed circuit board laminates, and as an additive FR in ABS plastics. SUNCHEM supplies TBBPA with purity ≥99%, typical Br content 58.5%, in 25kg bags.
Our halogen-free (HFFR) range includes: BDP and RDP (phosphate esters for PC/ABS), APP (ammonium polyphosphate for intumescent coatings and PP), Melamine Cyanurate (for PA6/PA66), DOPO (reactive phosphorus for epoxy), Aluminum Hydroxide/ATH, and Magnesium Hydroxide. All are RoHS compliant and suitable for REACH-registered supply chains.
DOPO (9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, CAS 35948-25-5) is a reactive, halogen-free phosphorus flame retardant used in epoxy resins for high-performance PCB laminates, encapsulants, and structural composites. It provides excellent thermal stability (char formation) and is a key building block for phosphorus-containing epoxy hardeners.
Both are endothermic mineral flame retardants with smoke suppression. ATH (Aluminum Hydroxide, CAS 21645-51-2) decomposes at 180–200°C — suitable for PVC, EVA, and thermosets processed at lower temperatures. Magnesium Hydroxide (CAS 1309-42-8) decomposes at 300–330°C — preferred for polypropylene, nylon, and thermoplastics processed at higher temperatures.
Yes — all our halogen-free flame retardants (phosphorus-based and mineral) are RoHS compliant. TBBPA and DBDPE are not restricted under current RoHS/REACH, but compliance statements and SVHC declarations are available on request. SUNCHEM can provide full regulatory documentation including REACH SDS, MSDS, and RoHS compliance letters.
Most products are packed in 25kg paper bags or fiber drums. Liquid products (BDP, RDP) in 200kg drums or IBC tanks. Samples (100g–1kg) available for evaluation. Minimum commercial order: 25–100kg depending on product. Contact info@sunchemgroup.com with your specific requirement for a tailored quotation.
China's phosphate and magnesium ore resources are abundant and cheap, and the price of Chinese flame retardants is also very favorable in the world market. The Chinese government has listed flame retardants as one of the key materials in the 13th Five-Year Plan, which has led to the rapid development of production and promotion of flame retardants.
If you are not familiar with the Chinese market, then you will face many problems .
But through SUNCHEM, we will fully understand the needs of our customers and then recommend the most suitable suppliers to them. Because we purchase large quantities, we can control the quality and supply chain.

From September 2021, the price of phosphorus has been very high because China's electricity restriction policy and the rapid development of electric vehicles have made it impossible for Chinese phosphorus production to catch up with the market demand. However, SUNCHEM has its own phosphorus mine. Our TCPP, TCEP and TPP are currently leading the sales in China.
At present, China is also vigorously developing inorganic flame retardants, and we have helped our Korean customer successfully develop a lightweight aluminum hydroxide flame retardant. Inorganic flame retardants are an important research direction for us in the future.
We can also provide various kinds of polymer materials with flame retardants for OEM processing. We can meet the needs of our customers.
