POLYPROPYLENE RESIN COMPOSITION

摘要

A polypropylene resin composition which can provide a material having high strength and rigidity, reduced warpage, and such an excellent mechanical durability that it can be used even under the condition of a prolonged or repeated application of load. The composition comprises 40 to 75 wt % of modified polypropylene (a) prepared by melting a mixture of crystalline polypropylene with at least 0.01 to 2 wt % of an unsaturated acid, 0.1 to 3 wt % of an unsaturated silane and an organic peroxide, 10 to 35 wt % of glass fiber (b) and 15 to 45 wt % of powdery mica (c), wherein the total content of components (b) and (c) is within the range of 25 to 60 wt %.
