Title
(EN) Flame retardant polyethylene composition comprising polypropylene
Abstract
(EN)

The present invention relates to a flame retardant polymer composition comprising (A) a polyethylene, (B) a silicone-group containing compound, (C) an inorganic filler material, and (D) a polypropylene in an amount of 0.1 to 10 wt. % with respect to the total composition, to an article comprising said flame retardant polymer composition, in particular to a wire or cable comprising a layer made of said flame retardant composition and to the use of said flame retardant polymer composition for the production of a layer of a wire or cable. Furthermore, the invention relates to the use of a polypropylene in the production of a flame retardant layer for a wire or cable as a processing aid.
