Abstract
An elastomeric thermoplastic polyolefin composition comprising (i) an heterophasic olefin polymer composition comprising a crystalline propylene homopolymer of copolymer fraction and an elastomeric ethylene copolymer fraction and (ii) an elastomeric polymer having a hardness equal to or less than 90 points selected from the group consisting of copolymers of ethylene, ethylene-methyl acrylate copolyers, saturated or unsaturated styrene block copolymers and unsaturated norbornene polymers.
