EPDM vs Silicone Rubber | The Difference | Silicone

Temperature resistance of a rubber is vitally important in appliions that have varying temperature ranges. Choosing the incorrect rubber can result in melting, deforming and/or the material becoming brittle, which in turn will affect its physical properties and most likely cause failure. When compared with silicone rubber, EPDM is significantly inferior with a maximum …

Fire-resistance rating - Wikipedia
