HARD VINYL CHLORIDE RESIN PIPE

摘要

PROBLEM TO BE SOLVED: To provide a hard vinyl chloride resin pipe which is hard to be curved or has small amount of curvature even if it is irradiated by the sunlight or the like.

SOLUTION: The hard vinyl chloride resin pipe and the vinyl chloride resin are characterized in that the mean linear expansion coefficient in 0 to 50°C at temperature-rise speed of 5°C/min measured based on JIS K7197 is not more than 6×10-5/°C. The hard vinyl chloride resin pipe is characterized by consisting of at least one or more kinds selected from the group which consists of a composite vinyl chloride resin, needle-like or fiber-like inorganic substance and carbon fiber and glass fiber composed mainly a vinyl chloride homopolymer or a vinyl chloride.
