FOAMED FLEXIBLE VINYL CHLORIDE MOLDING OF SMALL COMPRESSION SET

摘要

PURPOSE:To obtain a molding having an expansion ratio of 1.2-2.5. CONSTITUTION:The molding is a foamed flexible vinyl chloride molding having an expansion ratio of 1.2-2.5 and a small compression set and made from a flexible vinyl chloride resin composition containing 100 pts.wt. vinyl chloride resin, 5-150 pts.wt. acrylonitrile/butadiene rubber having a solubility of 5-90wt.% in methyl ethyl ketone, 1-60 pts.wt. methyl methacrylate copolymer having a specific viscosity of 2.5 or above as measured in 100ml of a benzene solution containing 0.4g of the copolymer at 30 deg.C, and 20-200 pts.wt. plasticizer.
