gap filler type
Highly Conformable and High Heat Conducting Gel Materials
SARCON® Thermal Gap Filler Pads are highly conformable and high heat conducting gel materials in a versatile sheet form. They easily fit and adhere to most all shapes and sizes of components, including protrusions and recessed areas.
Features
- Gap filler materials are supplied in a fully cured state and remain
pliable, easily conforming to minute surface irregularities. - The basic Gap Filler Pad series can be further enhanced for
special handling and die-cutting requirements. - UL94 V-0 certified. (with exceptions)
