Polypropylene composition for timing belt cover of car

摘要

The present invention is an inorganic filler, such relates to a polypropylene resin composition for automotive timing belt cover, specifically, poly molding while improving the mechanical strength and heat resistance to the propylene resin property, a silane treatment in order to maintain the dimensional stability fiber, glass fiber complex was added, and the polypropylene resin composition of the present invention a compound added to the rubber component for the intrinsic improvement automobile engine parts, as well as have a good heat resistance, rigidity and dimensional stability to the vibration damping properties also be used as an excellent automotive timing belt cover material for can.
