Title:
POLYVINYL CHLORIDE RESIN COMPOSITION AND POLYVINYL CHLORIDE RESIN SHEET
Document Type and Number:
Japanese Patent JP2017133000
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyvinyl chloride resin sheet having a property stably maintaining good tensile elongation property over long time and a polyvinyl chloride resin composition providing the same.SOLUTION: The polyvinyl chloride resin composition has a relationship of actual value of tensile breaking elongation Yand calculated value of tensile breaking elongation Y(%) calculated from a linear approximation formula (I) when acceleration time X is 2400 hours in the linear approximation formula (I): log(Y)=A log(X)+B calculated from a plurality of coordinates representing the actual value of tensile breaking elongation when the acceleration time is 1,000 hours or less satisfying the following formula (II): Y>0.7×Yin a double logarithmic graph represented by log(X) coordinate and log(Y) coordinate for the acceleration time X (hours) in a metal weather test and tensile breaking elongation Y (%) at the acceleration time X and the actual value of tensile breaking elongation Yof over 100% when molded to a sheet.SELECTED DRAWING: None
