Abstract
A multi-layer sheet made from olefin polymer materials includes (1) at least one outer layer of (a) a propylene polymer, (b) graft copolymer comprising a backbone of a propylene polymer material, to which is graft polymerized a vinyl monomer, either (a) or (b) optionally containing a nucleating agent, or (c) an olefin polymer composition, and (2) at least one layer made from alternating layers of a propylene polymer material and glass fiber mat.
