LOW GLOSS PC/ASA BLENDS FOR AUTOMOTIVE INTERIOR APPLICATIONS

摘要

A new low gloss acrylonitrile-styrene-acrylate (ASA) impact modified polycarbonate (PC) blend is developed to address product performance needs for the low gloss finish in automotive interior applications. To provide inherent matte and/or low gloss surface finish properties, low gloss additives were added in the PC/ASA blends. A direct comparison of the product performance between the optimized formulation and the existing commercialized low gloss PC/ASA material revealed improved low gloss characteristics of the resulting new product with enhanced heat and impact properties. The custom solution technology for the new low gloss PC/ASA product presented here enabled the new business development in automotive interior applications and is highly translatable across the automotive industry.
