SARCON® GR-Sd

SARCON® GR-Sd Very Low Modulus, 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.

RECOMMENDED APPLICATION
SARCON® GR-Sd RECOMMENDED APPLICATION

GR-Sd is the lowest modulus type of Gap Filler Type available. Ideally suited for applications requiring low compression force on the component. It offers the high performance that very easily conforms in and around protrusions and depressions on components to make complete, reliable physical contact.

・Absolute lowest modulus with high adhesion

・Easily fills air gaps, uneven surfaces

・Lower thermal resistance due to complete surface contact
