医用级聚甲醛是由缩醛共聚物树脂制成的,它使机械加工产品能够保持尺寸完整性,在高温下在水中和大多数化学品中保持稳定性。Pomalux产品不透明,有多种标准颜色和定制颜色。Pomalux的推荐灭菌技术包括ETO气体和蒸汽高压灭菌。消毒剂和杀菌剂通常对聚甲醛没有影响,但是酸性溶液可以降解聚合物。Westlake Plastics Company根据ASTM D6100制造所有缩醛挤压和压缩成型片材、板材和杆材。本规范涵盖了挤压和压缩成型板材、板材和杆的材料、尺寸、工艺和性能的要求和试验方法。应用范围包括:临时试验仪器处理医疗器械部件医用级聚甲醛的优点:批量控制和可追踪的树脂符合FDA法规21 CFR 177.2470和21 CFR 178.3297的要求,树脂满足USP六级规范的要求,应力消除激光标记 Medical grade Pomalux is made from acetal copolymer resin which allows machined products the ability to retain dimensional integrity, maintain stability in water and most chemicals at elevated temperatures. Pomalux products are opaque and are available in a wide array of standard colors as well as on a custom basis. Recommended sterilization techniques for Pomalux include EtO gas and steam autoclaving. Disinfectants and germicides generally have no effect on Pomalux, however, acidic solutions can degrade the polymer. Westlake Plastics Company manufactures all acetal extruded & compression molded sheets, plates and rods in accordance to ASTM D6100. This specification covers requirement and test methods for the material, dimensions, workmanship and the properties of extruded and compression molded sheets, plates and rods. Applications Include: Provisional trials Instrument handles Medical device components Advantages of Medical Grade Pomalux: Lot controlled and traceable Resin complies with FDA regulations 21 CFR 177.2470 and 21 CFR 178.3297 for colorants Resin meets the requirements of USP Class VI specifications Stress relieved Laser markable |
