EXTRUSION-MOLDED PRODUCT OF VINYL CHLORIDE RESIN

摘要

PROBLEM TO BE SOLVED: To provide the extrusion-molded product of a vinyl chloride resin which displays an extremely high anti-choking performance without lowering its impact strength. SOLUTION: The extrusion-molded product of a vinyl chloride resin is composed of a resin composition (A) with the content of an impact modifier limited to 0-4 pts.wt. to 100 pts.wt. of the vinyl chloride resin as an outer layer and a resin composition (B) with the content of the impact modifier blended proportionately high so as to reach 5-30 pts.wt. to 100 pts.wt. of the vinyl chloride resin as an inner layer. Thus, the extrusion-molded product significantly displays the extremely high anti-choking performance without lowering its impact strength through making it a multi-layer extrusion molded product.
