CHLORINATED VINYL CHLORIDE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition that is excellent in impact strength, heat resistance and solvent cracking resistance and is useful as a piping material by admixing chlorinated vinyl chloride resin and titanium dioxide at a specific ratio. SOLUTION: This composition comprises (A) 100 pts.wt. of chlorinated vinyl chloride resin of 60-70 wt.% of chlorination degree and (B) 0.1-10 wt.% of titanium oxide of 0.01-0.3μm particle sizes. The molded products from the resultant resin composition can be expectedly used as a piping material in which solvents tend to stay.
