extremely compressible gap filler type

Highly Thermally Conductive and Non-Flammable Interface Materials

SARCON® Silicone Extremely Compressible Gap Filler Type (Putty Type) is a highly conductive and thermally conductive, non-flammable interface materials. The surface consistency is excellent for filling small air gaps and uneven mating surfaces, making reliable contact with various shapes and sizes of components.

Features
  • Very low compression force at high compression rate.
  • Suitable for gaps as small as 0.3mm or less.
  • UL94 V-0 certified.
  • Available in three formulations

Highest Thermal Conductivity
extremely compressible gap filler type
Highly Thermally Conductive and Non-Flammable Interface Materials

SARCON® XR-Um and XR-v is the highest thermally conductive thin film Extremely Compressible Gap Filler Type (Putty Type). The material’s putty nature greatly contributes to reduction of contact resistance and consequently to its low thermal resistance. It is a customer friendly material due to its easy application by printing.
SARCON® XR-v-Al , XR-Um-Al has one surface with aluminum film, which enables users to remove the carrier film after installation (before operation) with no-pull-out effect.

Features
  • Putty nature enables low contact thermal resistance.
  • Low Molecular Siloxane content is very low.
  • Has a flame retardant of UL specification 94 V-0.
