China’s plastic flame retardant material is mainly based on decabromodiphenyl ether, but decabromodiphenyl ether in combustion will produce toxic carcinogenic polybrominated dibenzofuran and other substances, and make it some countries to resist the use of. Therefore, flame-retardant materials also develop towards the direction of [...]
