进口材料EPDM三元乙丙橡胶密封圈O型圈

EPDM三元乙丙橡胶密封圈: 具有很好的耐候性、耐臭氧性、耐水性及耐化学性。可用于醇类及酮类，还可用于高温水蒸气环境之密封。适用于卫浴设备、汽车散热器及汽车刹车系统中。不建议用于食品用途或是暴露于矿物油之中。一般使用温度范围为 -55~150 ℃。

在耐化学酸碱腐饨性能方面一般会采用氟胶或者三元乙丙橡胶0型密封圈，简单的说两者的区别:氟胶耐化学能更广一些，氟胶耐温度会更高，可以达到 240度，而三元乙丙橡胶0型圈只可以达到150度，氟胶可以耐油累介质，而三元乙丙橡胶不可以。三元乙丙橡胶的优势在于价格较低，多用于污水处理或者其它水处理产品中。

三元乙丙橡胶英文名称EPDM简称EP。三元乙丙橡胶常见的颜色是黑色，也可以做成任何不通的颜色，只要您提供色号或者样品给我们就可以为您生产出来。三元乙丙橡胶的主链是不含双键的完全饱和的直链型结构，其侧链上有二烯泾，这样就可用硫磺硫化。三元乙丙橡胶具有优良的耐老化性，

耐臭氧性，耐候性，耐热性(可在:120℃环境中长期使用)，耐化学性(如醇，酸，强碱。氧化剂)，但不耐脂肪族和芳香族类溶剂侵蚀。三元乙丙橡胶在橡胶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，三元乙丙橡胶有突出的耐蒸汽性能，可制作耐蒸汽膜片等密封制品。三元乙丙橡胶已广泛用于洗衣机，电视机中的配件和门窗密封制品，或多种复合体剖面的胶条生产中。
