Use of at least two polyolefins as anti - flow in a tpe fireproof

摘要

The present invention relates to the use of at least two polyolefins p1 and p2 as anti - creep and / or agent anti - drop in a composition of the flame-retardant type, characterized in that: p1 comprises at least one monomer chosen from among a - olefins and at least one other monomer chosen from vinyl esters of carboxylic acids; p2 comprises at least one monomer chosen from among a - olefins and at least one unsaturated monomer with an epoxide function or carboxylic acid anhydride; polyolefins p1 and p2 represent more than 10% by weight, p2 is at least 5% by weight and the ratio p1 / p2 is greater than 1, and said thermoplastic elastomer (tpe) is less than 55% by weight, on the total weight of the composition.
