Patent ID: 6855402

Claim:
A weather resistant plastic laminate, comprising: a cap surface plastic layer of glycol modified polyethylene terephthalate (PETG); and a rigid polymeric substrate plastic layer having the cap surface plastic layer fused or adhered to the substrate layer; wherein the rigid polymeric substrate plastic layer comprises polyvinyl chloride (PVC) or chlorinated polyvinyl chloride (CPVC) or high impact polystyrene (HIPS) or polyacrylonitrile-butadiene-styrene (ABS) or polyacrylate-styrene-acrylonitrile (ASA) or polycarbonate (PC); wherein the rigid polymeric substrate plastic layer has essentially no plasticizer; wherein the cap surface plastic layer contains opacifying pigment and contains UV absorber; and wherein the cap surface plastic layer protects the rigid polymeric substrate plastic layer during exterior usages from sunlight, UV radiation and heat; and wherein the cap surface plastic layer has thermal expansion and contraction characteristics approximate to thermal expansion and contraction characteristics of the rigid polymeric substrate plastic layer.
