- Light weighting is important to improve energy efficiency in the automotive industry. In this paper, high performance unfilled polypropylene copolymer (PPCP) material was selected and developed to reduce weight and cost without compromising on functional requirements for interior trims such as door trims, lower pillar trims, scuff trims and rear quarter trims (RQT). Interior trims are loaded with challenging requirements such as stiffness, dimensional stability, haptic feel, scratch resistance, cleanability, thermal stability, toughness, low emission and weathering resistance. Reactor polymerised PPCP material compound met these requirements by having ultra-flow behaviour, optimum tensile strength, balanced modulus - impact strength, scratch resistant, low emission and improved thermal properties. The combination of material, optimized part and tool design led to weight savings and considerable cost reduction.
