Today's automotive interior trim market is divided roughly equally between polypropylene copolymers and ABS, with both materials providing excellent performance in a wide variety of trim applications. It is interesting to note that some automotive originating equipment manufacturers (OEM) have strong preferences for one resin, while other OEM's strongly prefer the other, for very similar parts. This paper explores two of the reasons for these different preferences: first, the choice of test methods can lead to much different conclusions regarding which product is superior in a given area; and second, the various OEM's place different weight on the many variables involved in the decision. 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.
