硅橡胶具有卓越的耐高低温性能、耐老化性能、优良的介电性能、生理惰性及其它一些特性。已成为现代科学技术不可缺少的高弹性材料之一。硅橡胶的主要缺点是强度性能,特别是抗撕裂强度低,从而限制了它的应用。因此提高硅橡胶的强度和抗撕性能的必要性对于其应用的范围至关重要。 

普通硅橡胶胶料主要组成是:生胶、补强性填料—常用的为白炭黑、防止白炭黑与生胶相互作用而结构化的结构控制剂、耐热添加剂—常用三氧二化铁以作为交联剂的过氧化物。

高抗撕硅胶是采用高强度生胶,逐渐加入改性气相法白炭黑,以及其他辅助材料而成的,相比于普通气相硅橡胶所采用的气相白炭黑,改性气相法白炭黑具有独特的官能团,混炼成型起来具有更高的撕裂强度。

 高抗撕硅橡胶料主要可用来生产形状复杂的杂件电力产品护套垫片、薄膜各种挤出硅橡胶管条汽车吊耳硅胶板材表带等各种消费品。

MSK高抗撕气相胶MD7000系列可很好的满足以上各类材料生产物性需求。
