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, COC特性: 密度小, 吸水率小, 双折射率小, 高耐热性透明树脂, 机械性优良, 耐擦伤性良好, 易密封、不透水蒸气防湿, 介电常数低,高频性能好, 易成型. 主要用于:光学镜头、光学播音器、多边镜、角摸板用保护膜、液晶显示屏用导光板、光学半导体、光纤和分析化学仪器用池和槽。聚相比。这种材料主要用于要求玻璃般清晰产品,包括镜头,小瓶,显示器和设备。 TOPAS® 8007F-600 环烯烃共聚物 Topas Advanced Polymers, Inc. 产品说明: Product Description TOPAS 8007F-600 is a new robust film extrusion grade designed for blending with polyethylene (PE). It is an improved clarity amorphous resin with high stiffness, moisture barrier, chemical resistance, thermoformability and purity for food and general purpose applications. It is used in blends in both cast and blown processes, and in monolayer and multilayer products. Leading film applications include twist wrap, forming webs, protective packaging, shrink films and labels, and easy tear packaging. Industrial uses include formed PE and PP sheet products. For property enhancement at elevated temperatures, higher glass transition temperature (Tg) grades of TOPAS are recommended. Selected Applications Forming films (header bags, etc.) Protective packaging Shrink films and labels Twist films Decorative sheet Food packaging Food contact Leading Attributes Clarity, forming, barrier, purity, halogen-free Stiffness for downgauging, improved forming High shrink, low stress, gloss, toughness Outstanding deadfold, clean cutting Stiffness, chemical resistance, forming, even draw Not manufactured with BPA, phthalates, or halogens Broad regulatory compliance Related Grades for Packaging and Film Extrusion TOPAS 8007F-04 - ultimate clarity extrusion grade TOPAS 8007F-400 - robust extrusion grade especially for PE blends
TOPAS® 5013S-04 环烯烃共聚物 Topas Advanced Polymers, Inc. 产品说明: Product Description TOPAS 5013S-04 is a high flow injection molding grade with a 130°C heat distortion temperature. 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 healthcare and other high-tech products. The 5013 resin series features high flow characteristics for excellent mold detail replication. Lower leachables and extractables of TOPAS COC preserve content stability and quality, and chemical purity. This grade has a high heat distortion temperature to withstand 95°C PCR protocols, and is suitable for gamma or EtO procedures. Selected Applications Microfluidics Microplates and biochips Labware Optics Cuvettes Electronics Healthcare and food contact Leading Attributes Exceptional mold detail replication; machinable Heat and chemical resistant, clarity and purity Temperature resistance, clarity and purity Clarity, low birefringence, low moisture sensitivity More UV transparent than most resins (see 8007X10) Low dielectric constant, thermoplastic Broad regulatory compliance Related Grades for Injection Molding, Healthcare, Optics and Diagnostics TOPAS 5013L-10 - lubricated version for greater processing versatility TOPAS 6013S-04 - general purpose version with standard flow TOPAS 6013M-07 - broader processing version especially suited for IBM/ISBM TOPAS 6015S-04 - higher heat distortion temperature (150°C) for 134°C protocols TOPAS IT X1 - impact grade for applications requiring extra toughness
