    PPA性质：

结晶性热可塑性塑料，有明显熔点，Nylon6 Tm为220-230℃，Nylon66则为260-270，

Nylon本身具吸水基故有吸水性，成形前须干燥，温度过高干燥则尼龙粒变色。

 PPA用途：

1、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;

2、芯片组和插座、杯体焊接支座;

3、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;

4、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;

5、连接器、控制器、传感器、马达及其它关键电子部件

PPA (Polyphthalamide) has a tensile strength 20% higher than that of nylon 6 and higher than that of Nylon 66 at high temperature and high humidity, and has a 20% higher modulus of bend and greater hardness than that of Nylon 66, said PPA Polyphthalamide, ppas are resistant to prolonged tensile creep, and ppas are more resistant to gasoline, grease, and coolants than Paas. A high temperature resistant nylon, this material is resistant to sustained high temperatures up to 200 °C and maintains good dimensional stability. PPA Resin is a semi-aromatic polyamide based on terephthalic acid or isophthalic acid. Both semi-crystalline and non-crystalline, its glass transition temperature is about 255 ° F. The non-crystalline PPA is mainly used for barrier properties, and the semi-crystalline PPA is mainly used for injection molding and other melting processes. The latter is described in the following sections: A SEMI-CRYSTALLINE PPA resin, unless otherwise specified. The semicrystalline PPAS has a melting point of about 590 ° F and is supplied as opaque rectangular slices.
