UL polyurethane casting rigid foam decorative artificial wood
Description
In some developed regions of Europe, America, Australia and Southeast Asia, the decoration relievos outdoor, moldings indoor, frameworks and etc are produced from rigid polyurethane foam. SWD Urethane Co., USA developed rigid polyurethane foam artificial wood decoration materials which has been widely applied in the moldings production enterprises. After China entered WTO, many decoration moldings production companies transferred the production process to domestic then export the finished products abroad. Applied with technical formular of SWD USA, SWD Shanghai Co., produces artificial wood polyurethane combination materials and largely supplied to domestic decoration moldings and frames production enterprises.
