PPA(聚鄰苯二甲酰胺)是聚鄰苯二甲酰胺。PPA是一種具有半結晶和非結晶結構的熱塑性功能尼龍。PPA通過鄰苯二甲酸和鄰苯二胺的縮聚獲得。它具有出色的熱,電,物理和抗性。在化學性質方面的綜合性能。優異的機械性能在200°C連續高溫,濕度,油和化學腐蝕,包括高剛性,高強度,高尺寸精度,低翹曲和穩定性,抗疲勞,抗蠕變性。主要應用主要是無定形PPA。PPA具有高硬度和優異的機械強度,例如在高溫下的彎曲,拉伸和沖擊,并且耐長期拉伸蠕變。它的剛性和強度甚至超過PPS和PEEK在120°C的高溫下。特別適合替代壓鑄合金以降低成本。PPA具有比PA46更高的熱穩定性,更好的CTI電弧電阻和紅外回流能力。即使在150°C時,PPA也能對各種油類(如汽油,柴油,機油,礦物油和變壓器油)具有出色的耐受性。PPA適用于長期戶外使用,即使在高紫外線,高濕度和高溫等極端氣候條件下也不會導致物理性能下降。 。以上文獻若需轉載請備注出處:PBT樹脂 //shanglikaiguan.cn/
