详细介绍
过氯乙烯树脂(涂料级)(CPVC Resin)
化学名称:氯化聚氯乙烯树脂(CPVC)
性 能: 本品由聚氯乙烯树脂在溶剂存在下经氯气氯化而制得,具有优良的溶介特性,良好的电绝缘性、热塑性和成膜性,化学性能极为稳定,耐腐蚀,耐水,不易燃烧,能溶于酮、氯代烃、芳烃、酯及部分醇类。在很多领域有效取代氯化橡胶(CR)和氯磺化聚乙烯树脂。
用 途:制造过氯乙烯特种油漆,UPVC粘合剂及过氯乙烯防火涂料,过氯乙烯防腐漆,过氯乙烯防火漆,过氯乙烯腻子,皮革上光剂和制作塑料玩具等。
质量指标: 外观白色或微带浅色之疏松状细粒或粉末。应符合HG2002-91标准。

Chlorinated Polyvinylchloride Resin (CPVC) (Coating Grade)
Properties: It is made from PVC resin chlorinated by chlorine gas in solvent surrounding. It can offer good solubility, good electrical insulation, thermoplasticity and membrane forming capacity. It also can offer good chemical stability, resist corrosion and water, and be dissolved in acetone, hydrochloric ether, arene, ester and some alcohol. It can be used as the replacement of chlorinated rubber.
Usage: Special CPVC paint, UPVC adhesive, CPVC fire retardant coating, leather brightener, plastic toy. Also used in paint and varnish industry to produce different lacquers, enamels.
Packing & Storage: 20KG in plastic bag lined with polythene film bag; in cool, dry, airiness place; avoid insolation and moist.
Quality Standard: White/slightly tint loose powder/particle; standard: HG2002-91.
