SARCON® GR-Pm

SARCON® GR-Pm Highly Thermally Conductive and Non-Flammable interface materials

Feartures

SARCON® Sillicone Putty is a highly conformable, thermally conductive, non-flammable interface materials.
The surface consistency is excellent for filling small air gaps and uneven mating surface, making reliable contact with various shapes and sizes of components.
