Weight Reduction and Paint-Less of Plastic Parts of Automobile by Polypropylene/Elastomer Blends

Recently the technology on weight reduction such as foam injection molding and thin-wall injection molding has developed to reduce the weight of plastic parts of automobile. Paint-less technology by using pre-colored material has also developed to save the painting cost and the environmental load. This report introduces our study on filler-less polypropylene/elastomer blends that have high mechanical properties and colorability, and low density.
