Pigmented mineral-filled polypropylene (PP-PMF) is marketed as a potential alternative to ABS (acrylonitril-butyldiene-styrene) and ABS/ PC (acrylonitril-butyldiene-styrene/polycarbonate) for interior automotive components. PP-PMF is more easily damaged by surface scratch & mar, thus limiting its acceptance for interior applications. This study investigates the scratch and mar mechanisms of talc-filled PP and the effects of various additives on the scratch and mar resistance of PP-PMF. Talc filler provides higher modulus for PP. The addition of nucleation agent and lubricant showed beneficial effects.
