Sarcon© Silicone Putty is a highly conformable, thermally conductive, non-flammable interface material. Its thermal performance is equal to our most highly rated GR-m and XR-e Silicone Gap Filler Pads. Two formulations are available, GR-Pm and XR-Pe. The specifications for each can be found in the chart below. The surface consistancy is excellent for filling small air gaps and uneven mating surfaces, making reliable contact with various shapes and sizes of components. - Very low compression force at high compression rate
- Suitable for gaps as small as 0.3 mm or less
- UL 94V0
- Available in two formulations
