Halogen-free compositions of polyethylene and ethylene-vinyl acetate copolymer with limited flammability

摘要

The notified are halogenated compositions of polyethylene and a copolymer of ethylene and vinyl acetate with limited flammability, consisting of a filler and a plasticiser, which contain 40-50%weight.favourable 45 -48%weight. Antipyrene containing 17-30%weight. Pentaerythritol, 1 -3%weight. a hybrid additive based on haloiside, 6 -60%weight. melamine salts, 0-70%weight. Ammonium polyphosphate, 0-3%weight. zinc zinc, 0-20%weight. Red phosphorus. It is useful when they contain, as a hybrid additive based on haloise, haloise modified with dicamyl peroxide. It is useful when they contain, as a hybrid additive based on haloise, haloise modified with cyanide melamine. It is useful when they contain as a hybrid haloise-based additive a mixture of modified, as above, haloisites by weight 1:1. It's useful.when melamine contains melamine phosphate as a salt. It is useful when melamine polyphosphate contains melamine as a salt. It is useful when melamine cyanide contains melamine as a salt.
