POLYVINYL CHLORIDE-BASED RESIN COMPOSITION AND RIGID PROFILE EXTRUSION MOLDING

摘要

PROBLEM TO BE SOLVED: To obtain both a composition capable of improving the surface gloss of rigid profile extrusion molding without damaging the processability and mechanical characteristics and a rigid profile extrusion molding. SOLUTION: This vinyl chloride-based resin composition is obtained by compounding 100 pts.wt. of a polyvinyl chloride-based resin (I) with 3-8 pts.wt. of a vinyl chloride-based resin (II) for a paste and 1-50 pts.wt. of an inorganic filler.
