What Is Tetrabromobisphenol A Bis(dibromopropyl Ether) (BDDP)?
BDDP is tetrabromobisphenol A bis(2,3-dibromopropyl ether), CAS 21850-44-2. The brominated ether is an additive flame retardant for selected polymer systems. It is distinct from methyl-substituted HBCD replacement material CAS 97416-84-7 and from unetherified tetrabromobisphenol A.
The 2026 supply specification controls bromine ≥67.0%, whiteness ≥92%, melting range 106–120°C, acetone-insoluble matter ≤0.06% and volatile matter ≤0.30%. Powder or granule form should be selected against the feeding and dispersion requirements of the production line.
For polypropylene, polyethylene and styrenic formulations, assess dispersion, melt behaviour and the balance between additive loading and mechanical properties. Synergists and stabilizers should be selected through complete-compound trials; no universal loading or flame rating is assigned to the raw material.
Rubber and electrical polymer development require evaluation of cure or thermal-processing response, ageing, migration and end-use requirements. Minimize powder exposure and protect the material from contamination. The matched bulk solid reference is non-dangerous goods for transport.
