進口材料EPDM三元乙丙橡膠密封圈O型圈

EPDM三元乙丙橡膠密封圈: 具有很好的耐候性、耐臭氧性、耐水性及耐化學性。可用于醇類及酮類，還可用于高溫水蒸氣環境之密封。適用于衛浴設備、汽車散熱器及汽車剎車系統中。不建議用于食品用途或是暴露于礦物油之中。一般使用溫度范圍為 -55~150 ℃。

在耐化學酸堿腐飩性能方面一般會采用氟膠或者三元乙丙橡膠0型密封圈，簡單的說兩者的區別:氟膠耐化學能更廣一些，氟膠耐溫度會更高，可以達到 240度，而三元乙丙橡膠0型圈只可以達到150度，氟膠可以耐油累介質，而三元乙丙橡膠不可以。三元乙丙橡膠的優勢在于價格較低，多用于污水處理或者其它水處理產品中。

三元乙丙橡膠英文名稱EPDM簡稱EP。三元乙丙橡膠常見的顏色是黑色，也可以做成任何不通的顏色，只要您提供色號或者樣品給我們就可以為您生產出來。三元乙丙橡膠的主鏈是不含雙鍵的完全飽和的直鏈型結構，其側鏈上有二烯涇，這樣就可用硫磺硫化。三元乙丙橡膠具有優良的耐老化性，

耐臭氧性，耐候性，耐熱性(可在:120℃環境中長期使用)，耐化學性(如醇，酸，強堿。氧化劑)，但不耐脂肪族和芳香族類溶劑侵蝕。三元乙丙橡膠在橡膠中密度是低的有高填充的特性，但缺乏白粘性和互粘性。此外，三元乙丙橡膠有突出的耐蒸汽性能，可制作耐蒸汽膜片等密封制品。三元乙丙橡膠已廣泛用于洗衣機，電視機中的配件和門窗密封制品，或多種復合體剖面的膠條生產中。
