PA66
奥升德(Ascend)
产品描述
Vydyne R550H NT453 is general-purpose, heat-stabilized, hydrolysis-resistant, 50% 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 R550H NT453 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 R550H NT453 has excellent knit-line strength and fatigue resistance, which is essential for cycle testing with anti-freeze solutions.
Typical Applications/End Uses:
Vydyne R550H NT453 is successfully used in a wide range of injection-molding engineering applications. Typical parts include automotive clips, radiator endtanks and 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.
