Continual improvements in automotive manufacturing has increased the life expectancy requirements for interior trim components. Aerodynamic styling has yielded larger windshields, resulting in a greenhouse effect. This effect is compounded by the angle of the windshield, which permits greater light and heat exposure to the upper surfaces of the instrument panel. Urethane systems and slush molding PVC compounds are changing rapidly to adapt to these demanding requirements. Several PVC/urethane combinations will be reviewed to illustrate the importance of the proper selection of these materials. Measurements of performance characteristics such as discoloration, shrinkage, physical properties, fogging, and weatherability will be utilized to quantify overall durability trends. Slush molded PVC instrument panel skins interact with the flexible urethane foam backing. This interaction is accelerated by the light and heat present in the automobile interior, and may result in discoloration, shrinkage and general hardening of the instrument panel. New low stain urethanes have been introduced, which reduce the severity of these problems. These foams, when coupled with recent developments in PVC skin compounds, may produce significant improvements in long term durability of instrument panels.
