PPA 美国杜邦 HTNFR52G30NH-BK337 增强级，耐高温，电子电器

应用：

由于PPA树脂的杰出的物理、热和电性能，尤其是适中的成本，使它有广阔的应用范围。这些性能和优良的耐化学性一起，使PPA成为汽车工业许多用途的候选者。趋向更好的空气动力学车身设计连同更高性能的马达，将提高发动机箱的温度，使传统的热塑塑料显得不尽适用。这些新的要求使PPA成为制作下述部件的候选材料之一：汽车前灯反光器、轴承座、皮带轮、传感器壳体、燃料管线元件和电气元件。

电气元件的发展方向是小型化和高温团结，如红外固结和汽相团结，这需要PPA的优越性能。阻燃级PPA具有优良的电性能、很高的HDT值、高的高温弯曲模量、能以较小的溢料加工成长的薄壁部件，适合于制作开关设备、连接件、电刷座和马达托架。

矿物填料级PPA用于反光表面和镀金属方面的用途，包括汽车前灯、装饰用管件和硬件。未经增强的冲击改性级PPA有较好的均衡机械性、高温性能。较高的韧性且这些性能受湿度的影响很小，其用途包括油田部件、军用品、体育用品、风扇叶轮和齿轮及个人安全用品。

Application:

Because of its outstanding physical, thermal and electricalproperties, especially its moderate cost, PPA resin has a widerange of applications. Together with excellent chemical resistance,these properties make PPA a candidate for many uses in theautomotive industry. The trend towards better aerodynamic bodydesign, together with higher performance motors, will increase thetemperature of the engine case, making the traditionalthermoplastics seem unsuitable. These new requirements make PPAbecome one of the candidate materials for manufacturing thefollowing components: automobile headlamp reflector, bearing seat,pulley, sensor housing, fuel pipeline components and electricalcomponents.

The development direction of electrical components isminiaturization and high-temperature consolidation, such asinfrared consolidation and vapor phase consolidation, whichrequires the superior performance of PPA. Flame retardant PPA hasexcellent electrical properties, high HDT value, highhigh-temperature bending modulus, and can process thin wall partswith small overflow, so it is suitable for manufacturingswitchgear, connectors, brush holders and motor brackets.

Mineral filler grade PPA is used for reflective surfaces andmetal-plated applications, including automotive headlights,decorative pipe fittings and hardware. The unreinforced impactmodified PPA has better balanced mechanical properties and hightemperature properties. It has high toughness and these propertiesare slightly affected by humidity. Its uses include oil fieldcomponents, military products, sports goods, fan impellers andgears, and personal safety products.
