SARCON® GR14B
SARCON® GR14A Highly Conformable, Non-Flammable, Isolation and High Heat Conducting Gel materials.
Features
・ This product has a lower specific gravity and less oil bleeding than our conventional products.
・ Gap filler materials are supplied in a fully cured state and remain pliable, easy conforming to minute surface irregularities.
・ The basic Gap Filler Pad series can be further enhanced for special handling and die-cutting requirements.
CONSTRUCTIONS
Series | Characteristics | Constructions |
SARCON® GR14B-00 | Silicone compound with double sticky surfaces and Thermal Conductivity of GR14A material is 1.4W/m-K by using Hot Disk. | ![]() |
SARCON® GR14B-0H | Silicone compound as above GR14B-00 plus additional hardening of the top surface to facilitate handling and installation during complex assemblies | ![]() |
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.
