Abstract
Compositions, composite articles and process for producing same are provided from a reinforced polyvinyl halide composition (A) comprising a high molecular weight polyvinyl halide resin, a plasticizer, and a reinforcement material, such as glass fibers, in combination with (B) a composition having adhesion to (A). Preferably (B) comprises a thermoplastic compound selected from the group consisting of PVC, plasticized PVC, styrene derivatives, urethane derivatives, acrylic derivatives, acrylonitrile derivatives, polyester derivatives, and mixtures thereof, with the most preferred composition being an unreinforced, plasticized polyvinyl halide composition. The composite article exhibits good strength, low sag at high use temperatures, and lowered coefficient of thermal expansion for use in contact with metal or polymeric substrates such as panels. The composite having a coefficient of thermal expansion not significantly different than the substrates in contact therewith, provides enhanced permanence of adhesion and sag resistance.
