Vydyne® R540H是通用的,热稳定,抗水解,40%玻璃纤维增强PA66树脂。天然的,它是专门设计的,以最大限度地保留物理性质时,暴露在抗冻溶液在高温下。该产品也经过润滑以改善流动性,并提供优越的表面外观。与未增强的PA66相比,玻璃增强的Vydyne树脂具有更高的热变形温度、抗蠕变和更好的尺寸稳定性。这些产品对包括汽油、液压油和大多数溶剂在内的各种化学品具有良好的耐化学性。Vydyne® R540H是热稳定的,以最大限度地减少聚合物在使用中暴露于高温下的氧化降解。本产品在长期高温下可提高物理性能的保持力。此外,Vydyne® R540H还具有优异的编织线强度和抗疲劳性能,这对于使用防冻液进行循环测试至关重要。典型应用/最终用途:Vydyne® R540H成功应用于各种注塑工程应用。典型零件包括汽车夹子、散热器端部水箱、空调和燃油分配系统零件、电气连接器、外壳和线轴以及齿轮、轴承壳、盖和外壳等工业应用。 Vydyne R540H is general-purpose, heat-stabilized, hydrolysis-resistant, 40% glass-fiber reinforced PA66 resin. Available in natural, it is specifically designed to maximize the retention of physical properties when exposed to anti-freeze solutions at elevated temperatures. This product is also lubricated for improved flow and offers superior surface appearance. Glass-reinforced Vydyne resins provide higher heat distortion temperature, resistance to creep and better dimensional stability when compared with unreinforced PA66. These products have good chemical resistance to a broad range of chemicals including gasoline, hydraulic fluids and most solvents. Vydyne R540H is heat-stabilized to minimize oxidative degradation of the polymer when exposed to elevated temperatures in service. This product provides improved retention of physical properties under exposure to long term heat. Also, Vydyne R540H has excellent knit-line strength and fatigue resistance, which is essential for cycle testing with anti-freeze solutions. Typical Applications/End Uses: Vydyne R540H is successfully used in a wide range of injection-molding engineering applications. Typical parts include automotive clips, radiator end tanks, parts of the air-conditioning and fuel distribution systems; electrical connectors, housings and bobbins; and industrial applications such as gears, bearing shells, covers and housings. |
