| AV-742 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 -742 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，设计用于注射成型难度具有挑战的薄壁、复杂的、难以成型的形状或部件。如果部件的几何形状导致加工中不必采用低粘度牌号，建议采用AV- 722 SL30作为首要考虑，以利用该牌号较高分子量的优势，从而获得更好的耐磨损性，以及与韧性相关的更好的整体机械性能。该树脂可以使用常规设备和技术进行熔融加工。 AV- 742 SL30的潜在用途包括轴套、轴承、防磨条、耐磨环、轧辊和滑动摩擦组件中的其它部件。在自然状态下，该树呈黑色。&& |
