聚氯乙烯（PVC） 产品简介 聚氯乙烯（PVC）是以氯乙烯单体经聚合反应而制得的线型热塑性合成树脂。氯乙烯单体的合成路线按原料不同分为电石路线和石油路线。中国石化聚氯乙烯产品采用日本信越悬浮法聚合工艺和美国西方化学悬浮法聚合工艺制得的。产品具有良好的耐化学腐蚀性、电绝缘性和化学稳定性；由于含氯量高，具有很好的阻燃性和自熄性；产品易于成型加工， 可以采用挤出、注塑、压延、吹塑、压制、铸塑及热成型等多种成型方法进行加工。
产品用途 聚氯乙烯是应用最广泛的热塑性树脂之一，可以制作强度和硬度高的硬质制品如管材、管件、门窗等异型材和包装片材，也可以加入增塑剂制作非常柔软的制品如薄膜、片材、电线电缆、地板、合成革等。
主要生产企业及工艺列表 Manufacturers and Processes
Polyvinyl Chloride (PVC) is a linear thermoplastic resin produced by polymerization of vinyl chloride monomer. Due to the difference of raw materials, there are two methods of synthesizing vinyl chloride monomer - calcium carbide process and petroleum process. Sinopec PVC adopts two suspension process, respectively from Japanese Shin-Etsu Chemical Company and American Oxy Vinyls Company. The product has good chemical corrosion resistance, excellent electrical insulation property and fine chemical stability. With high chlorine content, the material has good fire retardance and self-extinguishing properties. PVC is easy to process by extrusion, injection molding, calendering, blow molding, compressing, cast moulding and thermal molding, etc.
Applications PVC is one of the most widely used thermoplastic resins. It can be used to make products with high hardness and strength, such as pipes and fittings, profiled doors, windows and packaging sheets. It can also make soft products, such as films, sheets, electrical wires and cables, floorboards and synthetic leather, by addition of plasticizers.
产品采用牛皮纸涂PP编织物复合袋包装或采用内涂塑PP编织布外袋、LDPE袋包装或散装，小包装净重25Kg/袋、大包装净重1250Kg/袋、1000Kg/袋、600Kg/袋或500Kg/袋。 产品应存放在通风、干燥的仓库内，远离火源，不得露天堆放，防止日晒和受潮。产品运输时必须用洁净有蓬的运输工具，防止雨淋。
Package, Storage and Transportation The resin is packaged in compound bags of kraft paper and coated PP woven material, or internally coated PP woven cloth exterior bags with LDPE interior bags, or packaged in bulk. The net weight of small package is 25Kg per bag and that of large package is 1250Kg, 1000Kg, 600Kg or 500Kg per bag. The resin should be stored in well-ventilated and dry warehouses against fire, sunlight and dampness, and should not be piled up in the open air. Clean and covered transportation vehicles should be used for transportation to prevent from rain.
