PURPOSE: The titled composition having improved flow properties during melting without damaging high impact resistance and wear resistance of ultra-high- molecular-weight polyethylene, obtained by blending an ultra-high-molecular- weight polyethylene resin with a widely used polyolefin resin in a specific ratio.
CONSTITUTION: 95W50pts.wt. (preferably 90W85pts.wt.) ultra-high-molecular- weight polyolefin resin(having ≥1,000,000mol.wt., ≤0.01 melt index at 20kg load) is blended with 5W50pts.wt. (preferably 10W25pts.wt.) widely used polyolefin resin(polyolefin resin modified with silane having preferably ≤150,000mol.wt.), to give the desired composition.
EFFECT: Capable of providing a molded article having improved mechanical properties in high productivity by using a widely used extrusion or injection molding machine.
