Title:
RIGID VINYL CHLORIDE-BASED RESIN TUBE
Document Type and Number:
WIPO Patent Application WO/2019/230949
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a rigid vinyl chloride-based resin tube having excellent heat-shielding properties and color tone stability. This rigid polyvinyl chloride-based resin tube contains a polyvinyl chloride-based resin, and two or more kinds of metallic inorganic pigments, has a whiteness of 50 or more and a solar reflectance of 20% or more, and has excellent heat-shielding properties and color tone stability. Preferably, the rigid polyvinyl chloride-based resin tube further includes a stearic acid salt, wherein the content of the stearic acid salt is 10-54 parts by weight per 1 part by weight of the metallic inorganic pigments exhibiting the color. More preferably, the rigid polyvinyl chloride-based resin tube further includes a calcium carbonate, wherein the content of the calcium carbonate is 5 parts by weight or more per 100 parts by weight of the polyvinyl chloride-based resin.
