牌号简介 About |
---|
AV-722 SL30是 AvaSpire 聚芳醚酮(PAEK)耐磨损牌号,旨在为非润滑和润滑环境中的产品提供更低的磨损率。除了优异的耐磨损性外,该树脂也具有PEEK公认的超高性能,包括即使在高温下也具有出色的耐化学性、机械强度和刚度、以及长期耐高温热氧化稳定性。 AV -722 SL30树脂被配制为包括碳纤、石墨、聚四氟乙烯(PTFE)在内的耐摩擦/耐磨损三元添加剂系统。由于改性体系的存在,耐磨损性能优于 PEEK牌号,同时更具成本效益。 该树脂是一种低流动性(高粘度)牌号,设计用于注射成型不太复杂的形状或部件。凭借其在低剪切速率下的高粘度特性,该树脂具有高熔体强度,因此可挤塑加工成各种棒材、管道、管材和型材等原型产品。该树脂可以使用常规设备和技术进行熔融加工。 AV-722 SL30 is a wear resistant grade of AvaSpire® polyaryletherketone (PAEK) designed to provide low wear rates in both non-lubricated and lubricated environments. In addition to the outstanding wear resistance, the resin also offers the outstanding combination of ultra performance attributes commonly known for PEEK. These include: chemical resistance, mechanical strength and stiffness, even at elevated temperatures, as well as long-term and high-temperature thermal-oxidative stability. AV-722 SL30 is formulated with the ternary anti-friction/anti-wear additive system comprised of carbon fiber, graphite, and polytetrafluoroethylene (PTFE.) It offers wear resistance performance comparable to PEEK grades with this modifier system while being more cost-effective. This resin is a low melt flow (high viscosity) grade designed for use in injection molding of less intricate shapes or parts. By virtue of its high viscosity at low shear rates, the resin has high melt strength, and, as such, is extrudable into stock shapes such as rods, pipe, tubing and profile. The resin can be melt processed using conventional equipment and techniques. Potential applications for AV-722 SL30 include bushings, bearings, wear strips, wear rings, rollers, and other parts or components where sliding friction is encountered. The resin is black in color in its natural state. |
