Cyclic Olefin Copolymer (COC) is an amorphous polymer made by several polymer manufacturers. COC is a relatively new class of polymers when compared to polypropylene and polyethylene. This material is primarily used in applications requiring glass-like clarity including lenses, vials, monitors, and medical devices. 环烯烃共聚物（COC）的是一种非晶态的高分子聚合物，只有几个别制造商生产。
COC是一个相对较新级别的聚合物，与聚丙烯和聚乙烯相比。
这种材料主要用于要求玻璃般清晰产品，包括镜头，小瓶，显示器和医疗设备。
COC has a transparency similar to glass in its natural form. Typical COC material will have a higher modulus than HDPE and PP. Due to its chemistry, the higher the modulus, the more brittle it becomes. COC also has a high moisture barrier for a clear polymer along with a low absorption rate. In medical applications, COC is noted to be a high purity product with low extractables. COC is also a halogen-free product. 环烯烃共聚物的自然形态，类似玻璃。
典型环烯烃共聚物材料，比高密度聚乙烯和聚丙烯模量较高。
由于其化学，模量越高，就越变得脆。
环烯烃共聚物也是一个防潮湿的，低吸水率的高透明聚合物。
在医疗应用领域，环烯烃共聚物是一个低萃取物纯度高的产品。
环烯烃共聚物也是一个无卤素产品。
Some properties will vary due to monomer content. These include glass transition temperature, viscosity, and stiffness. The glass transition temperature of these polymers can exceed 150 °C 德国TOPAS coc 5013L-10 Extrusion COC can be extruded with both *t and blown film equipment. These films are then used in consumer applications including food and pharmaceutical packaging. Commercial structures of COC used in blister packs are typically coextruded with a thick COC core and thin polypropylene skin layers. PVC and PvDC can also be placed on the skins via lamination. Profile extrusion is another method that can be used to make COC reinforced tubes or pipes. 德国TOPAS coc 5013L-10 Molding While there are many different types of molding, COC is primarily used in injection molding. Its natural clarity makes it useful in lenses for cameras, projectors and copiers. COC has little to no extractables which make it useful in diagnostic and medical devices. Most COC grades can also undergo sterilization by gamma radiation, steam and ethylene oxide. 德国TOPAS coc 5013L-10 Fiber Spinning COC has unique electrical properties that resist dielectric breakdown and have a very low dielectric loss over time. Because of this COC is used in filter media that require a charge retention to work properly TOPAS 5013L-10 COC TOPAS 5013S-04 COC TOPAS 6013EC-01 COC TOPAS 6013L-17 COC TOPAS 6013M-07 COC TOPAS 6013S-04 COC TOPAS 6015S-04 COC TOPAS 6017S-04 COC TOPAS 7010F-600 COC TOPAS 8007D-61 COC TOPAS 8007F-04 COC TOPAS 8007F-400 COC TOPAS 8007F-500 COC TOPAS 8007F-600 COC TOPAS 8007S-04 COC TOPAS 8007X10 COC TOPAS 9506F-04 COC TOPAS 9506F-500 COC TOPAS 9903D-10 COC TOPAS Elastomer E-140 COC TOPAS IT X1 COC COC 美国泰科纳 6013F-04 COC 美国泰科纳 6015S-04 COC 美国泰科纳 8007F-04 COC 美国泰科纳 8007F-400 COC 美国泰科纳 8007S-04 COC 美国泰科纳 8007X10 COC 美国泰科纳 9506F-04 COC 美国大赛璐 8007S-04 COC 日本瑞翁 1020R COC 日本瑞翁 1060R COC 日本瑞翁 1060RZUV1 COC 日本瑞翁 1420R COC 日本瑞翁 1600R COC 日本瑞翁 330R COC 日本瑞翁 340R COC 日本瑞翁 480M COC 日本瑞翁 480R COC 日本瑞翁 480S COC 日本瑞翁 690R COC 日本瑞翁 750R COC 日本瑞翁 E48 COC 日本瑞翁 E48R COC 日本瑞翁 ZNR1430R1 COC 日本三井化学 APL-5014DP COC 日本三井化学 APL5514ML COC 日本三井化学 APL6011T COC 日本三井化学 APL6013T COC 日本三井化学 APS8009TC COC 日本宝理 5010L COC 日本宝理 5013 COC 日本宝理 5013LS-01 COC 日本宝理 5013X16 COC 日本宝理 6015S-04 COC 日本宝理 8007F-04 COC 日本宝理 8007-F400 COC 日本宝理 9506 COC 日本宝理 6015 COC 日本宝理 8007 COC 日本JSR FX4727 COC 日本JSR G6810B COC 日本JSR G7810 COC 日本JSR R5300U COC 日本JSR R7100 COC 日本JSR RH5200 COC 日本大阪天然气 OKP4 COC 日本大阪天然气 OKP4HT 本司可提供SGS、UL黄卡、物性表、MSDS、COA、REACH等有关于塑胶原料环保的各种资料。
