PURPOSE: A polypropylene resin composition is provided to obtain vehicle interior of light weight, and to improve impact strength, flexural modulus, tensile strength, elongation, heat strain temperature, etc. CONSTITUTION: Polypropylene resin composition comprises 15-17 weight% of jute, 8-12 weight% of coupling agent, 20-30 weight% of rubber, and residual impact polypropylene. The coupling agent is maleic anhydride grafted polypropylene of which weight average molecular weight is 1,000-5,000. The specific gravity of the jute is 1.3 g/cm^3. The rubber is selected from olefinic rubber, silicon rubber, ethylene-octene copolymer rubber, etc. |
