FIRE RETARDANT INSULATING MATERIAL

摘要

A polymer material which contains ethylene groups and is made fireproof by an organic brominated additive, antimony oxide and optionally a phosphate or pyrophosphate containing titanate. It contains: (a) a non-reticulated polymer matrix containing 40% to 60% by weight of polyethylene and 40% to 60% by weight of a copolymer of ethylene and of alkyl acrylate; (b) 25% to 35% by weight related to the weight of the polymer matrix of the organic brominated additive which is decabromodiphenyloxide, octabromodiphenyl or hexabromodiphenyl; (c) 8% to 19% by weight related to the weight of the polymer matrix of antimony oxide (d) and optionally 0.1% to 0.5% by weight related to the weight of the polymer matrix of an organo phosphate containing a phosphate or pyrophosphate radical.
