硅橡胶的特性

1. High temperature performance. The remarkable characteristic of silicone rubber is its high-temperature stability. It can still be maintained at temperatures above 200 ° C. There is no significant change in mechanical properties with a certain degree of flexibility, resilience, and surface hardness.

2. Low temperature performance. The glass transition temperature of silicone rubber is generally - 70~- 50 ° C, and the special formula can reach - 100 ° C, indicating its excellent low-temperature performance. This is of great significance to the aerospace industry.

3. 抗衰老。耐候硅橡胶中的 Si-O-Si 键对氧气、臭氧和紫外线非常稳定。不含添加剂，具有优良的耐候性。

4. 电气性能。硅橡胶具有优良的绝缘性能和优异的耐电弧性。

5. Physical and mechanical properties. Silicone rubber has poorer physical and mechanical properties at room temperature than ordinary rubber, but its physical and mechanical properties are superior to ordinary rubber at high temperatures of 150 ° C and low temperatures of - 50 ° C.

6. 耐油和耐化学性。普通硅橡胶具有中等耐油性和耐溶剂性。

7. 透气性。在常温下，硅橡胶对空气、氮气、氧气、二氧化碳等气体的渗透率是天然橡胶的30-50倍。
