PPA (Polyphthalamide ) 聚鄰苯二甲酰胺,在高溫高濕狀態下,PPA的抗拉強度比尼龍6高20%,比尼龍66更高;PPA材料的彎曲模量比尼龍高20%,硬度更大,能抗長時間的拉伸蠕變;且PPA的耐汽油、耐油脂和冷卻劑的能力也比PA強;一種耐高溫尼龍,這種材料可以耐200℃的持續高溫,并且還能保持良好的尺寸穩定性。[這些性能和優良的耐化學性一起,使PPA成為汽車工業許多用途的候選者。趨向更好的空氣動力學車身設計連同更高性能的馬達,將提高發動機箱的溫度,使傳統的熱塑塑料顯得不盡適用。這些新的要求使PPA成為制作下述部件的候選材料之一:汽車前燈反光器、軸承座、皮帶輪、傳感器殼體、燃料管線元件和電氣元件。
