SARCON® XR-m
Highly Conformable and High Heat Conducting Gel Materials.
Features
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.
CONSTRUCTION
| Series | Characteristics | Constructions |
| SARCON® XR-m | Silicone compound with double sticky surfaces and Thermal Conductivity of XR-m material is 17.0W/m-K by using GHP (11.0W/m-K by using Hot Disk) |  |
RECOMMENDED APPLICATION
In areas where space between surface is uneven or varies and where surface textures are a concern regarding efficient thermal transfer, the supple consistency of Gap Filler Pad is excellent for filling air gaps and uneven surfaces.
