COC是具有环状烯烃结构的非晶性透明共聚高分子物体。 具有与PMMA(聚、酸树脂)相匹敌的光学性能以及具有高于PC(聚碳酸酯)的耐热性,还由于低吸水性而具有比PMMA和PC更加优良的尺寸稳定性等,在市场上获得了很高的评价。再有,改善水蒸汽气密性,增加刚性、耐热性,能赋予易切割性等优点,作为适合于用作传统材料的改性用材料,它在包装材料领域里的开发活动正在推进之中。 是一种基于的茂金属催化剂技术的高品质和高纯度非晶性环状树脂。在标准要求很严的器械装置和检查诊断器具等领域,作为高品质和高成本的石英玻璃和 PDMS(polydimethylsiloxane)等的替代材料, 具有特性和性价比。欧洲的广大地区正在改用塑料来制作预充器以取代玻璃材料。预充器可改善制造过程中的破损废品率,减轻重量,不会产生金属类溶出物,同时还具有的水蒸气阻隔性(长期保存性)以及不亚于玻璃的高透明性等优良特性,因此是玻璃材料的替代材料。塑料瓶也保持着同样的特性,特别适合需要长期保存的场合
通用级COC树脂:具有高透明性、转印性、耐热性等,作为透明通用工程塑料,广泛用于导光板、汽车零部件、容器、光盘等各个领域。
光学级COC树脂:具有优异的光学特性,可以用于照相机与打印机、光学读取头、镜子等光学零部件。此外,具有透明性、高屏蔽性、低杂质性,可以用于用途、生物用途。还有,具有低电容率与低介质损耗,可以用于高频连接器、天线基板。COC塑料是由TOPAS ADVANCED POLYMERSGmbH公司开发出来的环烯烃类共聚物(COC)的商品名,是具有环状烯烃结构的非晶性透明共聚高分子物体。

产品说明:
Product Description
TOPAS 9506F-500 is a low glass transition film extrusion blending grade. It is a medium clarity resin with high stiffness, moisture barrier, chemical resistance, thermoformability and purity for food and healthcare applications. It is used in monolayer blended cast applications, and in coextrusions in both cast and blown processes, for a variety of film and sheet products. Leading applications include shrink film and labels where shrinkage at moderate temperatures is desired. For property enhancement at elevated temperatures, higher glass transition temperature (Tg) grades of TOPAS are recommended.
Selected Applications
Shrink films and labels
Thermoformed PE films
Food packaging
Healthcare and food contact
Leading Attributes
High shrink, low stress, gloss, clarity, toughness
Improved material distribution, stiffness, depth

Product Description
TOPAS 6015S-04 is a general purpose injection molding grade. It is a glass-clear amorphous polymer with outstanding moisture barrier, chemical resistance, high purity and a non-reactive surface making it an excellent choice for optics, healthcare and other high-tech products. Lower leachables and extractables of TOPAS COC preserve food and drug stability and quality. It is a non-polar substrate that does not promote adsorption, denaturation, aggregation, or precipitation like glass can. This grade has a high (150°C) heat distortion temperature to withstand 121°C and 134°C steam and dry heat sterilization protocols, as well as gamma and EtO procedures.
Selected Applications
Drug delivery
Prefilled syringes, vials, cartridges
Bottles and tubes
Surgical instruments
IV containers and components
Labware
Optics
Electronics
Food packaging
Healthcare and food contact
Leading Attributes
Low leachables & extractables, low water transmission

COC也是热封薄膜的一个很好选择。热封性能南热封强度、热粘强度和热封起始温度表征。COC共混物模量的增加一般能将热封强度提高lO%~20% 。随着冷却的进行,COC迅速从Tg以上的橡胶态转变成Tg以下的高模量态。这种突变一般能将热粘强度(冷却0.1s后的热封强度)提高多达100 。热粘强度对于立式成型/灌装/封合T艺来说十分重要,因为在这种T艺中,是在热封材料仍然处于热态时就将包装物放人其中。COC所产生的模量增量提高了立包袋的“站立”性能。

COC是新型的具有环状烯烃结构的非晶性透明共聚分子材料,其具有作为光学部件非常重要的低双折射率,以及低吸水性,高刚性等优良性能。COC具有与PMMA相匹敌的光学性能,以及具有高于PC的耐热性,还具有比PMMA和 PC更加优良的尺寸稳定性等。COC密度小,比PMMA和PC约低10%,有利于制品轻量化;饱和吸水率小COC吸水率远低于PMMA,不会产生因吸水导致物性下降的影响,对外观要求较高的制品,加工时必需干燥,由于含有性和异向性小的单体,因而为非晶型透明材料,双折射率小。COC可用成型、吹塑成型、挤出成型,中空成型及玉延成型等多种方式加工。如果采用注塑成型,在对制品冷却阶段快速冷却,有利于增加制品的透明度,但要注易制品开裂现象。
