【Amodel PPA美國蘇威性能描述】

聚對苯二酰對苯二胺（PPA）塑料的熱變形溫度高達(dá)300℃以上，連續(xù)使用溫度可達(dá)170℃，能滿足您所需的短期和長期的熱性能。它可在寬廣的溫度范圍內(nèi)和高濕度環(huán)境中保持其優(yōu)越的機(jī)械性特性—強(qiáng)度、硬度、耐疲勞性及抗蠕變性。增韌呂級PPA結(jié)合優(yōu)越的韌度與一定范圍的硬度和柔性，在扣件中要求一次性使用的剛性、以及重復(fù)性使用中撓屈性的良好選擇。同時提供特殊品級的產(chǎn)品應(yīng)用于可噴涂和可電鍍的表面，防火性、耐乙二醇性及反身性要求的應(yīng)用。

PPA Superior Properties of strength, toughness and hardness, aswell as its good heat resistance, chemical resistance and crackresistance PPA can still maintain strength and hardness due to hightemperature and high humidity, mETAL PPA plastics can be replacedin a way that traditional nylon and polyester can not. They alsohave superior surface gloss. It can be colored to avoid surfacespraying, thereby helping to reduce the degree of surface scratchesand scratches. PPA plastic also has good processability, and allowsshort injection cycle time compared with PA46: √ PPA has higherthermal stability than PA46, √ PPA has better CTI / ARC resistanceand infrared cocurrent ability than PA46; √ PPA has better chemicalresistance than PA46.
