硅橡胶分热硫化型（高温硫化硅胶HTV）、室温硫化型（RTV），其中室温硫化型又分缩聚反应型和加成反应型。热硫化型又分甲基硅橡胶（MQ）、甲基乙烯基硅橡胶（VMQ，用量及产品牌号最多）、甲基乙烯基苯基硅橡胶PVMQ（耐低温、耐辐射）。硅橡胶是指主链由硅和氧原子交替构成，硅原子上通常连有两个有机基团的橡胶。普通的硅橡胶主要由含甲基和少量乙烯基的硅氧链节组成。苯基的引入可提高硅橡胶的耐高、低温性能，三氟丙基及氰基的引入则可提高硅橡胶的耐温及耐油性能。硅橡胶最高是由美国以三氯化铁为催化剂合成的。1945年，硅橡胶产品问世。1948年，采用高比表面积的气相法白炭黑补强的硅橡胶研制成功，使硅橡胶的性能跃升到实用阶段，奠定了现代硅橡胶生产技术的基础。扩展资料：硅橡胶在医疗领域的主要用途：1、硅橡胶防噪音耳塞：佩戴舒适，能很好的阻隔噪音，保护耳膜。2、硅橡胶胎头吸引器：操作简便，使用安全，可根据胎儿头部大小变形，吸引时胎儿头皮不会被吸起，可避免头皮血肿和颅内损伤等弊病，能大大减轻难产孕妇分娩时的痛苦。3、硅橡胶人造血管：具有特殊的生理机能，能做到与人体“亲密无间”，人的机体也不排斥它，经过一定时间，就会与人体组织完全结合起来稳定性极为良好。4、硅橡胶鼓膜修补片：其片薄而柔软，光洁度和韧性都良好。是修补耳膜的理想材料，且操作简便，效果颇佳。在众多的合成橡胶中，硅橡胶是在其中的佼佼者。它具有无味无毒，不怕高温和抵御严寒的特点，在三百摄氏度和零下九十摄氏度时“泰然自若”、“面不改色”，仍不失原有的强度和弹性。参考资料来源：百度百科-硅橡胶
