Abstract:
A polyolefin thermoplastic composition having elastic properties, being in the form of a powder, intended for the production of skins, by slush molding, which contains fractions, one being formed of a propylene-based homopolymer or copolymer, another being formed of an ethylene-based copolymer and the final one being formed of an elastomer, characterized in that it is composed of:a) from 97 to approximately 5 parts by weight of a matrix composed of at least one semi-crystalline polymer containing at least 50 mol % of propylene and of at least one at least partially crosslinked polyolefin elastomer;b) from 3 to approximately 95 parts by weight of at least one non-crosslinked polymer containing at least 50 mol % of ethylene; andc) from 0 to 6 parts by weight of an internal mold-release agent per 100 parts by weight of components ""a"" and ""b""; and is free of mineral oil based softening agents.
