POLYPROPYLENE RESIN COMPOSITION |
摘要 |
The resin composition is composed of specified amounts of (a) crystalline ethylene-propylene block copolymer having an ethylene content of 3 - 30 wt.% and a MI of 4, (b) a ethylene-propylene copolymer rubber and/or ethylene-propylene-diene terpolymer rubber the rubbers having a propylene content of 10 - 90 wt.% and a Mooney viscosity of 15 - 110, (c) a talc which has been surface-treated with a surface treatment agent, (d) barium sulfate having an average particle size not greater than 1 mu m, (e) prismatic or acicular calcium carbonate having a particle size not greater than 5 mu m and an aspect rastio of at least 2.5, and (f) a nucleating agent. The aggregate among of components (c), (d) and (e) is 5 - 35 % by weight of the resin composition. |
