higher speed riding was plastic formmasse with improved stability

摘要

A fire retardant (flame retardant, flame resistant) plastic moulding composition of improved stability comprises from 50 to 85% by weight, based on the total amount of the moulding composition, of an olefin polymer and from 15 to 50% by weight, based on the total amount of the moulding composition, of a flameproofing system comprising from 80 to 50% by weight of an ammonium polyphosphate of the formula (NH4PO3)n, in which n is a number from 200 to 1000 (= component A) and from 50 to 20% by weight of a product of the reaction of tris(2-hydroxyethyl) isocyanurate (THEIC) of the formula IMAGE with an aromatic polycarboxylic acid of the formula Ar(COOH)m (= component B). The flameproofing system to be employed according to the invention increases both the processing temperature of the plastic moulding composition and significantly reduces the water solubility of parts of the moulding composition after processing. In addition, the flameproofed plastic parts have a reduced tendency to exude constituents of the flameproofing system.
