Configuration

SARCON RUBBER TYPE’s versatility in thermal management applications is doubly enhanced by way of the variety of end-use configurations possible, and the many standard material formulations available in each.
The silicone rubber based materials offer other useful elements such as electrical insulation, protective covering and gasketing as integral features in most designs.
