詳細介紹
過氯乙烯樹脂(涂料級)(CPVC Resin)
化學名稱:氯化聚氯乙烯樹脂(CPVC)
性 能: 本品由聚氯乙烯樹脂在溶劑存在下經(jīng)氯氣氯化而制得,具有優(yōu)良的溶介特性,良好的電絕緣性、熱塑性和成膜性,化學性能極為穩(wěn)定,耐腐蝕,耐水,不易燃燒,能溶于酮、氯代烴、芳烴、酯及部分醇類。在很多領域有效取代氯化橡膠(CR)和氯磺化聚乙烯樹脂。
用 途:制造過氯乙烯特種油漆,UPVC粘合劑及過氯乙烯防火涂料,過氯乙烯防腐漆,過氯乙烯防火漆,過氯乙烯膩子,皮革上光劑和制作塑料玩具等。
質(zhì)量指標: 外觀白色或微帶淺色之疏松狀細粒或粉末。應符合HG2002-91標準。

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.
