硅胶O型圈食品医用级硅胶密封圈美标O型圈规格表AS-568系列

硅胶O型圈的中硅胶是一种橡胶材料，因为其性能特殊耐温范围广，化学性能优异，故与氟胶一起被成为特种橡胶。硅胶被广泛用于制作各种密封件，包括硅胶密封圈，硅胶O-RING，硅胶套等。

硅胶O型圈英文名称：Silicone gasket （分子结构） CH3 CH=CH —(Si—O)(Si—O) 甲基乙烯基硅橡胶， CH3 CH3

硅胶O型圈理化性能：硅胶密封圈是以从石英中获得的硅元素为基础，并由硅原子粘附诸如甲基、乙烯基等侧链而形成的饱和非极性橡胶。不同的侧链会导致硅橡胶具有不同的特性。甲基乙烯基硅橡胶（VMQ）是应用较多的一种硅橡胶材料。硅胶密封圈具有优异的耐热性、低温弹性和特别优异的耐氧化和臭氧的性能，具有高透气性和对气体透过的选择性。良好的电绝缘性能（体积电阻大于10欧.cm，击穿电压在30kv/mm以上），耐电晕性和耐电弧性。但添加导电碳黑、镍粉、铝粉、银粉，又可得适当之导电性（体积电阻可至5-0.02欧.cm）。硅胶密封圈的表面能较低，具有吸湿性，可起隔离作用。耐水，但耐水蒸气不佳，压力超过50psi以上不建议使用。与大多数的油、化学物和溶剂兼容。一般硅橡胶耐酸碱性佳，耐极性溶剂尚可，不耐烷氢和芳香族油品。不建议使用于大部分浓缩的溶剂、油品、浓酸及稀释后的火碱溶液中。特种硅橡胶还具有耐辐射、耐燃、耐油等性能。它的拉伸强度低，抗磨损能力弱，一般不用于动密封。

硅胶O型圈温度范围：-60℃~225℃，特殊硅橡胶高温可达300℃，而低温可至-100℃。（TR10可在-100℃下）硬度范围：邵氏A25度至90度。

硅胶O型圈颜色：黑色、棕色、绿色、白色、红棕色、黄色、兰色、红色、橙。

橡胶材质说明：

丁腈橡胶（NBR）耐热120度，硬度70左右，黑色，耐油性好

90度丁腈胶（NBR）同为丁腈胶材质，硬度高，耐压效果更好

硅胶（VMQ) 耐热200度，耐油一般，无毒，防水好（有耐高温硅胶，可耐280度）

氟胶（FKM) 耐热250度，耐油性好，耐磨，耐腐蚀

三元乙丙（EPDM)耐热150度，不耐油，耐酸碱

氢化丁腈（HNBR)耐高温性为130-180℃,耐寒性为-55~-38℃

常用材料：丁腈橡胶（NBR）氟橡胶（VITON）三元乙丙橡胶（EPDM）硅橡胶（VMQ）氯丁橡胶（CR）丁苯橡胶（SBR）氢化丁腈（HNBR）等等几十种橡胶材料，亦可提供邵氏硬度50～90的产品;

SIL硅橡胶O型密封圈: 具有很好的耐热、耐寒、耐臭氧、耐大气老化性能。有很好的绝缘性能。但抗拉强度较一般橡胶差且不具耐油性。适用于家用电器如电热水器、电熨斗、微波炉等。还适用于各种与人体有接触的用品，如水壶、饮水机等。不建议使用于大部份浓缩溶剂、油品、浓酸及氢氧化钠中。一般使用温度范围为 -55~250 ℃。环保，抗臭氧性，抗候性，耐热性，耐寒性，耐化学性，抗油性，耐磨性，抗变形性，年限30年。
