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)
