Improved Heat and Light Stability of Vacuum Formable PVC Alloys for Automotive Interior Trim Applications

An improved PVC alloy with a soft feel that is vacuum formable has been developed for better durability in heat and light. This sheet is intended for automotive interior trim applications that utilize a PVC alloy coverstock backed with a pour-in-place polyurethane foam.

Accelerated heat (oven aging 120°C) and light (Xenon Arc) aging show this material to have excellent durability characteristics. This new material contains no cadmium-based pigments or stabilizers. It has been designed to help meet the automotive industry's desire to reach a 5- and 10-year life with the economical benefits of a thermoforming process.
