IMPREGNATED PRODUCT, POLYOLEFIN COMPOSITION CONTAINING THE IMPREGNATED PRODUCT AND METHOD FOR MANUFACTURING THE SAME, AND MOLDED PRODUCT OBTAINED FROM THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an impregnated product of a polyolefin from which a molded product excellent in a limit PV value and a sand-abrasion loss is obtained, and to provide a composition of the impregnated product and a method for manufacturing the same. SOLUTION: An impregnated product prepared by impregnating a polyolefin porous powder or porous product with a lubricant. An average particle size of the polyolefin porous powder or porous product is preferably 10-3,000μm. The polyolefin is preferably a super high-molecular polyethylene. The lubricant is preferably a silicone oil having a high viscosity. An abrasion resistance-improving agent for the polyolefin consisting of the impregnated product. A method for manufacturing the polyolefin composition comprising mixing a crosslinked product obtained by the reaction of polyolefin with a crosslinking agent and the abrasion resistance-improving agent. The polyolefin composition containing a crosslinked product and the abrasion resistance-improving agent. A method for manufacturing a polyolefin molded product comprising molding the polyolefin composition. A polyolefin molded product obtained by molding the polyolefin composition.
