在兩種橡膠并用時影響共硫化的因素有橡膠相的混合性，兩種橡膠的硫化特性及配合劑的分散性，據(jù)知，三元乙丙膠與丁苯膠、天然橡膠或聚丁二烯膠等并用時，分散狀態(tài)為微觀不均勻分散，與硫化體系無關(guān)。但ＮＲ／ＳＢＲ、ＮＲ／聚丁二烯并用體系同ＥＰＤＭ并用體系的摻和狀態(tài)基本上都是相同的。因而分散狀態(tài)并不是一個太大的問題，問題在于硫化特性方面，決定因素為橡膠的硫化速度和硫化程度，當(dāng)采用硫化體系時還決定于雙鍵的數(shù)量、位置和分布，此外，還決定于ＥＰＤＭ第三單體的種類。 </p> <p> 當(dāng)三元乙丙膠并用少量不飽和橡膠時強(qiáng)度比較低，其原因在于兩種橡膠的硫化速度不同，二烯類橡膠先行硫化，而ＥＰＤＭ卻還停留在未硫化狀態(tài)，因此，為要提高共硫化性，研究一下如何提高ＥＰＤＭ含量大的膠料的強(qiáng)度是有意義的。錦湖汽車部件用三元乙丙膠三元乙丙的交鏈速度和硫化時間隨著硫化類型和含量而改變。</p> <span
