Chinese name: Tetrabromobisphenol A-bis(2,3-dibromopropyl ether) English name: TetraBromoBisphenol A (2,3-Dibromopropyl) ether Alias: Octabromoether; 2,2-bis[4-(2 ,3-dibromopropoxy)-3,5-dibromophenyl]propane; Flame retardant octabromoether CAS number: 21850-44-2 Molecular formula: C21H20Br8O2 Molecular weight: 943.6143 Appearance: white powder Main content %: ≥ 92 Bromine content%: ≥67 Melting point ℃: ≥ 105 Volatile matter 80, 2h: ≤0.2 Whiteness %: ≥93 Use: It is a good flame retardant for olefin resins, mainly used in various grades of polypropylene and polypropylene fibers , styrene-butadiene rubber, butadiene rubber, etc., with remarkable flame-retardant effect Packaging: plastic-coated woven bag, lined with plastic
Brominated SBS Other names: Brominated butadiene/vinyl aromatic copolymer Brand: RX-971CAS code: 1195978-93-8 Appearance: White or off-white solid Bromine content: ≥65%5% Thermal weight loss: ≥256℃ Volatile content: ≤0.3% PH: 5.5-7.5 Product use: Brominated SBS is a new type of polymer environmental flame retardant, mainly used in external wall insulation material board EPS, extruded board XPS.It is an excellent substitute for the discontinued flame retardant hexabromocyclododecane (HBCD).Product performance: It has good thermal stability. According to the research, it has a relatively small bearing force when melting the mixture, injecting molds, and extruding foam processes. Generally, it does not thermally degrade, and the process temperature can reach above 230°C; heat removal stability In addition, when the polymer using this product is foamed, it has good compatibility with the foaming agent used for foaming; the flame retardancy of brominated SBS is comparable to that of the discontinued hexabromo
