POLYPROPYLENE RESIN COMPOSITION HAVING THERMAL RESISTANCE, HIGH RIGIDITY AND LOW WARPAGE PROPERTIES

摘要

The present invention provides a low flexible polypropylene resin composition, which comprises a polypropylene resin composition comprising 20∼69 percent by weight of a polypropylene, 1.0∼30 percent by weight of a modified polypropylene modified by grafting unsaturated carboxylic acid or derivatives thereof and 30∼50 percent by weight of a glass fiber and mica as an inorganic fillers and 0.01∼2.0 percent by weight of a organicsilane compounds. The low flexible polypropylene resin composition of this invention has excellent heat resistance and stiffness.
