OLEFIN RESIN COMPOSITION FOR INJECTION MOLDING |
摘要 |
An olefin resin composition for injection molding which comprises (A) an olefin resin composition comprising ultra-high-molecular-weight polyethylene having an intrinsic viscosity of 10 to 40 d l /g as measured in decalin as the solvent at 135 DEG C and low-molecular-weight or high-molecular-weight polyethylene having an intrinsic viscosity lower than that of the ultra-high-molecular-weight polyethylene, in which the ultra-high-molecular-weight polyethylene is present in an amount of 15 to 40% by weight based on the sum of both of the polyethylenes and the two polyethylenes as a whole have an intrinsic viscosity [ eta ]c of 3.5 to 15 d l /g and a melt torque T lower than 4.5 kg.cm, and (B) 1 to 70% by weight, based on the olefin resin composition, of an additive selected from the group consisting of fine particulate inorganic fillers, fibrous fillers and liquid and solid lubricants. |
