What is silicone rubber material?

Silicone rubber (Silicome Rubber) is a new type of heat-resistant polymer elastic material. Silicone rubber is characterized by high temperature resistance, excellent cold resistance, the temperature range is-50 degrees+260degrees. Excellent aging resistance (ozone resistance, oxidation resistance, radiation resistance, light resistance, climate resistance). In free state, there is no significant change in performance after outdoor exposure for several years.
And has excellent electrical insulation performance, and tasteless, non-toxic in line with the national hygienic standards.
