A composition suitable for thermoforming which demonstrates good grain retention at thin gauges, low gloss and whose cost is competitive for many applications, particularly in the automotive industry, is described. This composition contains (a) 10-35 wt.% of polypropylene or an ethylene/propylene copolymer, (b) 0-30 wt.% uncrosslinked ethylene propylene copolymer rubber having an ethylene content 60-80 wt.%, (c) 10-25 wt.% of an ionomeric copolymer of ethylene and an α, β-unsaturated C3-C8 carboxylic acid, (d) 2-6 wt.% of a copolymer of ethylene and glycidyl acrylate or glycidyl methacrylate, (e) 5-20 wt.% polyethylene, and (f) 0-25 wt.% of an ethylene alpha-olefin copolymer elastomer. |
