OLEFIN POLYMER RESIN COMPOSITION FOR PIPE AND PIPE PRODUCED BY THEREOF

摘要

PURPOSE: An olefin polymer resin composition for pipes is provided to ensure high extrusion and low extrusion load, and good productivity due to little generation of die-deposit and fume. CONSTITUTION: An olefin polymer resin composition for pipes comprises an olefinic polymer and a fluorine-based processing aid containing fluoroelastomer. The ethylene content within the fluoroelastomer is 35~55 weight% and the fluorine content is 45~65 weight%. The fluoroelastomer comprises poly(vinylidene fluoride)(PVDF), poly(hexafluoropropylene)(PHFP), and poly(tetrafluoroethylene)(PTFE).
