硅胶O型圈主要用于仪器、仪表、设备等在密闭条件下的吸潮防锈。与普通硅胶干燥剂配合使用,指示干燥剂的吸潮程度和判断环境的相对湿度。作为包装用硅胶干燥剂,广泛用于精密仪器、皮革、服装、食品、品和家用电器等。 同时,硅胶O型圈因为其食品级用途可以用来做奶嘴等与人体直接接触的用品.缺点:硅橡胶O型圈的价格相对于其他硅橡胶制品比较昂贵,同时在耐腐蚀性上也不如其他的橡胶制品,在机械拉伸方面强度也比较低。硅胶主链由硅 (-si-o-si) 结合而成。具有的耐热、耐寒、耐臭氧、耐大气老化。有很好的电绝缘性能。抗拉力强度较一般橡胶差且不具耐油性。
硅胶O型圈的物性如下:
1.耐候性
有机硅具有比其他高分子材料更好的热稳定性以及耐辐照和耐候能力。有机硅中自然环境下的使用寿命可达几十年。
2.
硅胶O型圈十分耐生物老化,与动物体无排异反应,并具有较好的抗凝血性能。
3.低表面张力和低表面能
硅胶O型圈低表面张力和低表面能是它获得多方面应用的主要原因:疏水、消泡、泡沫稳定、防粘、润滑、上光等各项优异性能。
4.电气绝缘性能
有机硅产品都具有良好的电绝缘性能,其介电损耗、耐电压、耐电弧、耐电晕、体积电阻系数和表面电阻系数等均在绝缘材料中名列前茅,而且它们的电气性能受温度和频率的影响很小。因此,它们是一种稳定的电绝缘材料,被广泛应用于电子、电气工业上。有机硅除了具有优良的耐热性外,还具有优异的拒水性,这是电气设备在湿态条件下使用具有高可靠性的保障。
5.耐温特性
有机硅不但可耐高温,而且也耐低温,可在一个很宽的温度范围内使用。无论是化学性能还是物理机械性能,随温度的变化都很小。
