Tetrabromobisphenol A (TBBPA) is the world’s highest-volume brominated flame retardant, used both reactively and additively. Its bromine content is ~59%.

Tetrabromobisphenol A (TBBPA) has the CAS number 79-94-7 and the chemical formula C15H12Br4O2.

Tetrabromobisphenol A is used for printed circuit boards and electronic laminates (reactive), and flame-retardant ABS housings for electronics and appliances (additive).

Used reactively, it is chemically bound into epoxy resin backbones; used additively it works in the gas phase releasing bromine radicals. It pairs with antimony trioxide as a synergist in additive applications.

Epoxy resins and printed circuit boards (reactive), and ABS, HIPS and polycarbonate blends (additive).

TBBPA is a brominated flame retardant; the vast majority is consumed reactively in epoxy for PCBs, where it is bound into the polymer. REACH/RoHS documents available on request.

Reactive use is dictated by resin stoichiometry; additive loadings in ABS are typically ~10-18% with antimony trioxide synergist.

Store in a cool, dry, well-ventilated place away from heat, ignition sources and direct sunlight, in sealed original packaging and away from strong oxidisers. Refer to the SDS for full handling guidance.

Tetrabromobisphenol A is supplied in bulk, typically as 25 kg bags or 500/1000 kg jumbo bags on pallets. Shandong Haiwang Chemical accommodates flexible MOQs for trial and full container-load orders – contact us for current options.

Yes. Shandong Haiwang Chemical is a manufacturer (not a trader) and exports Tetrabromobisphenol A worldwide. Technical data sheets, COA and samples are available on request; contact the sales team for a quotation and lead time.

Tetrabromobisphenol A is supplied as a white crystalline powder.

Typical specification: ≥99% purity. A Certificate of Analysis is provided with each shipment.

Tetrabromobisphenol A is very low solubility in water; soluble in acetone and methanol.

Tetrabromobisphenol A offers a melting point of about 178–181°C.

Stored sealed in a cool, dry place, Tetrabromobisphenol A has a shelf life of around 2–3 years.

Tetrabromobisphenol A has low acute toxicity, but avoid dust inhalation and skin or eye contact — use standard PPE and follow the SDS.

Tetrabromobisphenol A is typically used with antimony trioxide in additive applications (in reactive use it is bound into the resin).

Tetrabromobisphenol A is the most cost-effective high-bromine retardant and ideal for reactive use in epoxy/PCBs where it becomes part of the polymer.

Shandong Haiwang Chemical can provide REACH and RoHS documentation, third-party SGS test reports, a Certificate of Analysis (COA) and Safety Data Sheet (SDS), and manufactures under an ISO 9001 quality system.

Samples of Tetrabromobisphenol A are usually available within a few days, and bulk lead time is typically 1–2 weeks depending on volume. Haiwang exports worldwide (FOB China ports, or CIF and other Incoterms on request) with flexible terms such as T/T or L/C — contact the sales team for a quotation, HS code and current lead time.
