牌号简介 About |
---|
AvaSpire AV-621是未增强聚芳醚酮(PAEK) ,韧性和冲击强度高于PEEK(聚醚醚酮) ,同时保留了PEEK所具有的大多数有用的关键性能。AV-621为低流动性牌号,类似于专门针对注塑成型和薄膜挤出的中等流动牌号AvaSpire AV-651。AvaSpire AV-621适于多种加工方式,包括模压成型、原型挤塑、以及注塑成型。 AV-621 专门开发用于追求耐化学性和机械强度平衡、赋予部件优美外观,并缩小超高分子间的性能差距的产品。所有这些特性使材料非常适合医疗保健、交通运输、电子、化学处理和其它工业用途。 AvaSpire AV -621在标准设备上用常规热塑性塑料熔融加工的方式加工,树脂呈均匀的不透明状,颜色类似PEEK的米色。 - AvaSpire AV-621 NT AvaSpire® AV-621 is an unreinforced polyaryletherketone (PAEK) that offers improved ductility and impact strength relative to PEEK while retaining most of the key performance attributes of PEEK. The AV-621 grade is the low melt flow (higher molecular weight) analog of the medium flow grade AvaSpire® AV-651 that is tailored primarily for injection molding applications as well as film extrusion. AvaSpire® AV-621 resin is suited for a variety of processing methods including compression molding, stock shape extrusion, as well as injection molding. AV-621 has been formulated for applications requiring a balance of chemical resistance and mechanical strength along with good part aesthetics, thereby bridging the performance gaps within the ultra polymers space. These and other properties make this resin well-suited for applications in healthcare, transportation, semiconductor, electronics, chemical processing, and other industries. AvaSpire® AV-621 is easily fabricated using conventional thermoplastic melt processing techniques and standard equipment. The resin has a uniform opaque appearance with a beige color similar to that of PEEK. AvaSpire® AV-621 NT |
