PPA 美国杜邦 HTNFR52G30NH-BK337 增强级，耐高温，标准级

主要应用: 汽车部件，包括燃油、传动及发动机系统，可减轻重量、降低成本并提供长时间的使用寿命； 芯片组和插座、杯体焊接支座；片状电容器、开关及微型喇叭、制作高密度的印刷电路板连接器；用于耐磨要求极高的场合，例如无润滑轴承、密封、轴承隔离环和往复开压缩机零件；连接器、控制器、传感器、马达及其它关键电子部件；半结晶态ppa树脂，特别注明的除外。半结晶态ppa的熔点约为590°f，以不透明矩形切片的形式供应。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。

main applications: automotive components, including fuel,transmission and engine systems, can reduce weight, reduce costsand provide a long service life; chip set and socket, cup bodywelding support; chip capacitor, switch and micro horn, makinghigh-density printed circuit board connector; it is used inoccasions with extremely high wear re, such asnon-lubricated bearings, seals, bearing isolation rings andreciprocating compressor parts; connectors, controllers, sensors,motors and other key electronic components;

semi-crystalline ppa resin, unless otherwise specified. themelting point of semi-crystalline ppa is about 590 ° f, and it issupplied in the form of opaque rectangular slices.

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 more motors, will increase the temperature ofthe engine case, making the traditional thermoplastics unsuitable.these new re make ppa become one of the candidatematerials for manufacturing the following components: automobileheadlamp reflector, bearing seat, pulley, sensor housing, fuelpipeline components and electrical components.
