作为一种多功能包装材料,COC塑胶原料 树脂TOPAS® 以其水蒸气阻隔性、保香性、死褶性等优良特性而被广泛用于许多领域。 此外,它还具有良好的 PE(特别是 LLDPE)相溶性,可按任意比例与之混合,因而被用作 PE 改质剂。 富有创意的立袋(standing pouch)正在被日益广泛地用于洗涤剂和食品等领域。 为使立袋能够自立,其外装薄膜应具有一定强度(厚度)。 如果在密封层 PE 中掺入 TOPAS®,则可在保持薄膜整体刚性的同时实现外装薄膜的薄壁化并有效减少包装材料的用量。 TOPAS® 是一种水蒸气阻隔性好并且适用于 PTP 的材料。 它可提高热成型性,使角部厚度保持均匀,并可改善刚性,从而可以实现薄壁化。 此外,几乎所有的 TOPAS® 等级美国FDA药物管理文档(DMF #12132)和 FDA 设备管理文档(MAF #1043)中作了注册,因此在包装品时尽可放心使用。 TOPAS® 6015S-04 环烯烃共聚物 Topas Advanced Polymers, Inc. 产品说明: 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 Non-ionic, does not promote adsorption like glass Minimally reactive Chemically resistant to alcohol, acetone, and acrylates Transparent, withstands EtO/gamma/steam sterilization Temperature resistance, clarity and purity Clarity, low birefringence, low moisture sensitivity Low dielectric constant, thermoplastic Not manufactured with BPA, phthalates, or halogens Broad regulatory compliance Related Grades for Injection Molding, Healthcare, Optics and Diagnostics TOPAS 6013M-07 - broader processing window, best for blow molding (IBM/ISBM) TOPAS 6017S-04 - our most heat distortion resistant IM grade (HDT=170°C) TOPAS IT X1 - impact grade for applications requiring extra toughness
