Silicone Rubber Statistics
- Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from −55 to 300 °C (−70 to 570 °F) while still maintaining its useful properties.
- This is done by heating large volumes of quartz sand to extremely high temperatures, often up to 1800 °C. From here, there are several processes where silicon is combined with methyl chloride and heated.
- Heat Stabilised grades of silicone contain an additive enabling them to operate at temperatures up to 260°C. These are available from 30° Shore A to 80° Shore A.
- High tear strength grades of silicone are FDA approved and are available from 50° Shore A to 70° Shore A. Naturally, these polymers are translucent, however, they can be pigmented to any colour you may require.
- It has incredible heat resistance that also helps it to have brilliant low-temperature flexibility to around -50°c. LSRs also have very low compression sets in the range of around 15%-20%.
