Abstract: An outer covering for the inside panel of a vehicle, whereby said panel includes a device for the accommodation and deployment of a safety air cushion, comprising the following: a support which includes a device for the accommodation and deployment of a safety air cushion; an inner layer consisting of a thermoplastic or thermosetting polymer foam material covering said support and fixed thereto; an outer covering or skin made from a thermoplastic polymer material covering the inner layer and fixed thereto. The inventive covering is characterized in that it does not have any incipient ruptures on the part of the panel which is used to accommodate and deploy the safety air cushion; it is made of a thermoplastic polymer material in the form of a powder by means of a free flow and means of molding in a hot mold; the chemical composition is indicated for the entire panel and is obtained from a thermoplastic elastomer composition.

Abstract: A bulk polymerized grafted and crosslinkable thermoplastic polyolefin powder composition having elasticity and flexibility properties, which is in the form of a powder intended for the production of flexible coatings by free flow over a hot mold, characterized in that it contains: a) from 100 to 5% by weight and preferably from 80 to 20% by weight of at least one homopolymer of ethylene and/or at least one copolymer containing at least 50 molar % of ethylene; b) from 0 to 95% by weight and preferably from 20 to 80% by weight of at least one thermoplastic elastomer; c) from 0.1 to 15 parts by weight and preferably from 0.5 to 10 parts by weight of a grafting agent, per 100 parts by weight of the accumulated components “a” and “b”. This powder composition is suitable for the production of flexible coatings by its free flow over a hot mold.

Abstract: A thermoplastic polyolefin composition having resilient properties is provided for producing interior trims for motor vehicles by slush moulding. The composition contains (a) around 95-5 parts by weight, preferably 97-10 parts by weight of a matrix consisting of at least one polymer containing at least 50 mol % of propylene and at least one at least partially cross-linked polyolefin elastomer; (b) around 3-95 parts by weight, preferably 5-90 parts by weight of at least one polymer containing at least 50 mol % of ethylene; and (c) 0-6 parts by weight of an internal release agent per 100 parts by weight of components (a) and (b).
