High Temperature Silicone

An increasing number of products demand reliable operation in very challenging environments. High temperature silicone rubber materials can withstand temperatures of up to 300°C for periods of up to 3 weeks.

Temperature peaks above 300°C can be tolerated for very short periods of time but they are not recommended for continuous operation at these temperatures. The effect of high temperatures tends to lead to a hardening and increasing brittleness of the silicone so it loses its elastomeric properties. High temperature silicone rubber is being used to replace many EPDM applications due to the increasing price of EPDM.
