摘要
A composite layered plastic article particularly resistant to outdoor exposure to heat, sunlight and UV degradation comprises a top surface exposed layer of PETG fused to a rigid substrate layer selected from PVC, or CPVC, or HIPS, or ABS, or ASA, or PC. The PETG layer is preferably co-extruded with the substrate layer and heat fused together to produce a laminated layered composite article. The composite layered plastic is particularly useful for color retention of dark colors and bright masstone colors, as well as pastel and white colors
