SARCON® GR45A

SARCON® GR45A Highly Conformable, Non-Flammable, Isolation and High Heat Conducting Gel materials.

Features

・ 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.

CONSTRUCTION
SeriesCharacteristicsConstructions
SARCON® GR45A-00Silicone compound with double sticky surfaces and Thermal Conductivity of GR45A material is 6.0W/m-K by using Hot Wire (4.5W/m-K by using Hot Disk)
SARCON® GR45A-0HSilicone compound as above GR45A-00 plus additional hardening of the top surface to facilitate handling and installation during complex assemblies
RECOMMENDED APPLICATION
SARCON® GR45A 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.
