進(jìn)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(xué)性?？捎糜诖碱惣巴?，還可用于高溫水蒸氣環(huán)境之密封。適用于衛(wèi)浴設(shè)備、汽車散熱器及汽車剎車系統(tǒng)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(xué)酸堿腐飩性能方面一般會(huì)采用氟膠或者三元乙丙橡膠0型密封圈，簡(jiǎn)單的說兩者的區(qū)別:氟膠耐化學(xué)能更廣一些，氟膠耐溫度會(huì)更高，可以達(dá)到 240度，而三元乙丙橡膠0型圈只可以達(dá)到150度，氟膠可以耐油累介質(zhì)，而三元乙丙橡膠不可以。三元乙丙橡膠的優(yōu)勢(shì)在于價(jià)格較低，多用于污水處理或者其它水處理產(chǎn)品中。
三元乙丙橡膠英文名稱EPDM簡(jiǎn)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(hào)或者樣品給我們就可以為您生產(chǎn)出來。三元乙丙橡膠的主鏈?zhǔn)遣缓p鍵的完全飽和的直鏈型結(jié)構(gòu)，其側(cè)鏈上有二烯涇，這樣就可用硫磺硫化。三元乙丙橡膠具有優(yōu)良的耐老化性，

耐臭氧性，耐候性，耐熱性(可在:120℃環(huán)境中長(zhǎng)期使用)，耐化學(xué)性(如醇，酸，強(qiáng)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(jī)，電視機(jī)中的配件和門窗密封制品，或多種復(fù)合體剖面的膠條生產(chǎn)中。
