高密度聚乙烯(HDPE)

聚乙烯(PE) Polyethylene (PE) 中国石化化工产品手册 / 合成树脂分册 / Sinopec Chemical Products Brochure / Synthetic Resin / 主要生产企业及工艺列表 Manufacturers and Processes 高密度聚乙烯 (HDPE) High-density Polyethylene (HDPE) 高密度聚乙烯是一种由乙烯与少量 -烯烃单体共聚而成的高 结晶非极性合成树脂,是在较低压力下合成,故又称低压聚 乙烯。其分子结构主要为线型结构,分子中支链少,结晶度 高,密度大,具有较高的使用温度、硬度和机械强度,耐化 学性能好。 中国石化高密度聚乙烯类别齐全、牌号众多,能够提供薄膜 料、中空料、拉丝料、注塑料、管材料、电缆料、氯化聚乙 烯用基础树脂等产品。 HDPE is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of α-olefin monomer. HDPE is synthesized under low pressure and is therefore also called low-pressure polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high degree of crystallization and high density. It can withstand high temperatures and has good rigidity and mechanical strength and anti-chemical corrosion. Sinopec produces a full grade of HDPE, which cover all fields of HDPE applications, including film, blow-molding, extrusion molding, injection molding, pipes, wire cable and base material for producing chlorinated polyethylene. 主要用途 高密度聚乙烯可应用于多种塑料成型方法。中空吹塑法可用 于制作各种瓶、罐及工业用槽、桶等容器;注塑成型制作各 种盆、桶、篮、筐等日用盛器、日用杂品和家具等;挤出成 型制作各种管材、捆扎带以及纤维、单丝等;还可用于制作 电线电缆的包覆材料和合成纸;加入大量无机填料后,还可 以制作钙塑包装箱、家具和门窗等,以代替木材和硬纸板。 Applications HDPE is suitable for many plastic molding methods. Blow molding can be used for making various types of bottles, cans and industrial tanks and barrels. Injection molding is used for making various containers and goods of daily use, such as basins, barrels and baskets and furniture. Extrusion molding is used for making pipes, strapping tapes, fibers and single filaments and can also be used for making wires cables covering materials and synthetic paper. After a large amount of inorganic filler is added, HDPE can also be used as an alternative to timber and cardboards for making calcium plastic packing containers, furniture, doors and windows. 生产企业 Manufacturers 所在地 Locations 产能 (万吨/年) Design Capacity (10,000
