THERMOPLASTIC ARTICLES MADE FROM RECYCLED PRODUCTS AND PROCESS FOR MAKING

摘要

A composite marine piling is provided comprising (a) a core element comprising filler and a thermoplastic resin and (b) a sheath comprising thermoplastic resin and a light absorbing/emitting material. The filled thermoplastic composition of the core element is melt processed (for example injection or compression molded) to produce the filled thermoplastic composite marine piling core element. The sheath covers top of the core element to provide the top portion of the piling with a light responsive sheath to enhance the visibility of the piling to ship operators. The piling is a useful replacement for wood pilings and has several physical property advantages and preferably being suitable made from recycled plastic and waste byproduct filler.
