Tgard™ 200B

Thermally Conductive Insulator

Product Description

The Tgard™ 200B is a high performance interface pad. Consisting of a silicone/boron nitride composite, these fiberglass-reinforced pads are used when the lowest thermal resistance and highest dielectric strength are required A high-tear, cut-through and puncture-resistant product, the Tgard™200B is tough and strong. Burrs cause no problems for the material and the pad will not dry out, crack or fail when pressured between mating parts. The Tgard™ 200B is available  in a variety of thicknesses  to meet customer requirements.
