VINYL CHLORIDE SOL COMPOSITION FOR CONTAINER LID LINER

摘要

PURPOSE:A vinyl chloride sol composition for container lid liner having a controlled lid openability which consists of vinyl chloride resin, a plasticizer, a silicone oil, and a lubricant selected from fatty acid amides and paraffin waxes. CONSTITUTION:A vinyl chloride sol composition for container lid liner which consists of 100pts.wt. of vinyl chloride resin(A), 50-100pts.wt. of a plasticizer(B), 0.5-10pts.wt. of a silicone oil(C) having a viscosity of 350-100000cps, and 0.5- 10pts.wt. of one or more lubricant(D) selected from fatty acid amides and paraffin waxes. As (A), less than 50% a vinyl chloride resin of a grain size of 10-50mu, obtained by suspension polymerization, is often used jointly for the regulating viscosity and as an extender. As (B), an epoxidated soybean oil, etc., is used and a colorant, a filler, etc., are also added.
