SARCON® SPG-50A

SARCON® SPG-50A Highly Thermal Conductive, Electricity Insulative, Low Viscosity type Silicone Compound

Features

Sarcon® SPG-50A is highly conformable/thermally conductive, low viscosity silicone compound. It provides a thermal solution for the recent trends of higher frequencies and integration in the development of electronic devices. Sarcon® SPG-50A easily forms and adheres to most of surfaces, shapes, and sizes of components. Sarcon® SPG-50A makes complete and reliable physical contact with the component and opposing surfaces. It provides handling properties that are superior to thermal grease & potting materials.

1) Suitable for filling the delicate gaps and still provide superior thermal transfer.
2) Highly conformable with very low compression forces.
3) Has excellent vibration absorption capabilities.
4) Maintains thermal properties across a wide temperature range.
5) Can be used to “Form-In-Place” and will remain form stable.
6) Requires no heat curing.
7) Will not cause corrosion on any metal surface
