dbdpe (dbdpe) is considered an excellent 10 pbde alternatives. dbdpe albermale by the united states pioneered the development of out of the relative molecular weight of 82% in the bromine content of 10 polybrominated diphenyl ethers with equivalent melting point of 345 degrees celsius, and 10 of its flame-retardant polybrominated diphenyl ethers equivalent to the combustion the process does not produce multi-bromobenzene right bit of dioxin (pbdd) and polybrominated dibenzofurans (pbdff), the light-fastness, low-exudative, anti-ultraviolet performance is better than deca-bde (dbdpo), so the main used as a new type of environmentally friendly flame retardant, is considered ideal to replace the 10 pbde products can be widely used as hips, abs resins and plastic pvc, pp and other flame-retardants, very broad prospects for development.
