A Comparison of Polypropylene and ABS Resins for Automotive Interior Trim Applications

This paper compares the relevant properties of various materials currently used in automotive interior trim applications, including: general purpose Acrylonitrile-Butadiene-Styrene (ABS), High Heat ABS, Polypropylene copolymers (PP), and filled PP. The intent of this paper is to present comparisons that will assist material and design engineers when selecting materials for interior trim applications. In addition, the paper discusses design issues that must be considered when converting between materials.
