Abstract
The present invention relates to a flame retardant polypropylene composition for a conduit, appliance, and/or automotive wire, comprising a flame retardant composition comprising: a) a base resin comprising a heterophasic propylene copolymer which comprises a polypropylene homo- or copolymer matrix and an ethylene propylene rubber dispersed in said matrix, and b) a metal hydroxide or hydrated compound, wherein the heterophasic propylene copolymer has a MFR2 below 0.8 g/10 min and a xylene cold soluble (XCS) fraction content between 1 and 15 wt % based on the total weight of the heterophasic propylene copolymer.
