ALFA Ultratherm 500

1 of 7 products in this brand
ALFA ULTRATHERM 500 is grease like silicone compound, filled with synthetic diamond and binding agent, this formulation promotes high thermal conductivity, low bleed, low thermal resistance, and function as heat transfer media. ALFA ULTRATHERM 500 is resistant to ozone and ultraviolet degradation and has good chemical stability, has low surface tension that enables it to wet most surfaces, which can lower the thermal contact resistance between the substrate and the material.
