KEP-8512、耐水蒸氣性能；耐極性油性能。(4)優(yōu)良的絕緣性能，體積電阻率1016Q·cm、擊穿電壓30～40MV/m、介電常數(shù)(1kHz，20℃)。(5)適用溫度范圍廣，比較低使用溫度-40～-60℃，錦湖 KEP-8512，可長(zhǎng)期在130℃條件下使用。乙丙橡膠的**主要缺點(diǎn)是硫化速度慢；與其它不飽和橡膠并用難，自粘和互粘性都很差，故加工性能不好。錦湖 KEP-8512</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="錦湖

在拉斷強(qiáng)度降低幅度比較大的并用比時(shí)（ＥＰＤＭ／ＮＲ＝７５／２５）碘值與拉斷強(qiáng)度的關(guān)系。拉斷強(qiáng)度隨碘值增大而直線上升，這說(shuō)明通過(guò)提高碘值可以改善并用膠的共硫化性，至于第三單體的效果，在同一碘值下進(jìn)行的比較表明，硫化速度快的乙叉降冰片烯ＥＰＤＭ膠共硫化性遠(yuǎn)為優(yōu)越，但決定的因素還是碘值。其次，調(diào)節(jié)硫化的特性也是有力的措施，并用膠的拉斷強(qiáng)度隨硫化促進(jìn)劑種類(lèi)的不同而有明顯的差異，采用低速促進(jìn)劑時(shí)的拉斷強(qiáng)度比采用超速促進(jìn)劑高得多，硫化速度（Ｖ）和硫化速度常數(shù)（Ｋ）與高不飽和橡膠的相應(yīng)值越接近越好。 </p> <p> 炭黑的影響如下：補(bǔ)強(qiáng)性越大，則拉斷強(qiáng)度越高，不同摻和方法的并用膠物理性能不同中兩種方法：一種為生膠摻和法，即先將生膠相互摻和，然后再加配合劑。另一種為母煉膠摻和法：系兩種生膠先分別加配合劑，***將兩種膠料摻和，性能以后者為佳。 </p> <p> <br />
