摘要:
Disclosed are articles and multi-zoned structures comprising a core zone comprising a wood polymer composition comprising a blend of cellulosic material and a thermoplastic polymeric resin; a cap zone disposed overlying at least a portion of the core zone comprises at least a portion of a surface of the multi-zoned structure; and, optionally, a transition zone disposed between the cap zone and the core zone. The articles are useful as wood polymer composites for use as planks, decking, stair treads, window casings, fencings, automobile interiors and pallets.
