Abstract
The present invention provides a multilayer polymer structure including an inner structural layer (A) of a rigid polymer composition, an intermediate or tie layer (B) of a polymer composition including a thermoplastic polyurethane, and an exposed or surface layer (C) of a polymer composition including a thermoplastic elastomer, which is preferably a partially cross-linked chlorinated olefin interpolymer alloy. Layer (B) is disposed between and bonded to layers (A) and (C). Preferably, layer (C) and layer (B) are bonded to layer (A) under pressure, at a temperature at which both the layer (C) and layer (B) are at or near their respective melting or softening points, but layer (A) is maintained at a temperature at which it remains dimensionally stable. Multilayer polymer structures according to the invention can be formed into decking material, conveyor belting and a variety of other products.
