They Are Made From Synthetic Silicon Compounds That Provide Excellent Thermal and Chemical Resistance, Making Them Ideal for Both Industrial and Medical Applications.
Key Properties of Silicone Rubber Sheets
The Key Advantage of a Silicone Rubber Sheet Lies in Its Ability to Maintain Performance in Extreme Environments. These Sheets Resist High Temperatures, UV Exposure, Ozone, and Moisture. as a Type of Heat-Resistant Rubber Sheet, They Also Retain Flexibility and Mechanical Strength Over Time. Their Non-reactive Nature Makes Them Suitable for Food and Pharmaceutical Use as Well.Whether used in gaskets, seals, medical devices, or industrial machinery, solid silicone provides a robust, long-lasting solution tailored for precision and performance. Available in multiple durometers and custom formulations, it meets the stringent requirements of modern engineering challenges.
