Is Silicone better than EPDM?
In general, Silicone can be utilised in more applications than EPDM although it can be used in some situations.
- Silicone can withstand a wider range of temperatures from -60C to +230C
- Silicone does not shrink during heating unlike EPDM which can decrease by 51% when heated over 150C
- EPDM has slightly higher mechanical strength than Silicone but is less resistant to heat and cold under those conditions.
