Multi-ply weatherable plasticizer-free sheet

Claim 1

A multi-ply, weatherable, plasticizer-free and deep-drawable sheet for the internal and external outfitting of automotive vehicles, comprising: a first layer comprised of an ethylene-propylene-diene terpolymer and a homopolymer and/or copolymer of propylene, produced by extrusion or calendering with a sheet thickness of 0.2 to 3 mm bonded to a second layer comprised of a crosslinked polyolefin resin-containing foam; said first layer containing 65-25% by weight of a partially crystalline ethylene-propylene-diene terpolymer comprising 65-82% by weight of ethylene; 18-35% by weight of propylene, and 3-8% by weight of a diene tercomponent, with a melt index MFI (230/5) of 0.5-2.0 g/10 min., a tensile strength of at least 10 N/mm 2 , and DSC maximum temperature of at least 40° C.; 3- 75% by weight of at least one propylene polymer selected from the group consisting of homopolymer and a copolymer of propylene, with a melt index MFI (230/2.16) of 0.2-2 g/10 min.; 0-10% by weight of fillers, comprising at least one of chalk, kaolin, talc, carbon black, silica and silicic anhydride; as well as, per 100 parts of said polymers: 0.1-1.0 parts by weight of stabilizers comprising at least one of sterically hindered phenolic antioxidants, phenolic phosphites and thioesters of aliphatic carboxylic acids; 0.1-2 parts by weight of a lubricant comprising at least one of metallic salts of carboxylic acids, montanic acid esters and hydrogenated hydrocarbon resins; 0-5 parts by weight of colorants; and 0-4 parts by weight of an extender oil; said second layer containing, in 100 parts by weight of the polyolefin-containing resin, at least 15% by weight of a polar, copolymerized monomer; said first layer and said second layer being adhesively bonded directly to each other by thermal pressure bonding or flame laminating.
