Thermal Insulators

Thermal Insulators Thermally Conductive Fabrics are fiberglass-reinforced ceramic filled silicone polymer sheets used to provide thermal transfer and electrical isolation where interface gaps are less than 20 mils and high torque application is required.

The fiberglass/ceramic-filled silicone compound construction provides excellent cut-thru resistance, high thermal transfer and effective electrical isolation.

These materials are typically used in computer power supplies and amplifiers where the combination of cut-thru resistance and high thermal transfer provides a cost-effective solution.
