Thermal Compounds

AOS Thermal Compounds offers the widest selection of non-silicone and silicone thermal greases available in the market. Since developing AOS Heat Sink Compound, the first Non-Silicone thermal grease, AOS has continued to expand its product line with advanced new formulas, including HTC (high thermal conductivity), XT (extreme temperature), and WC (water soluble formulas).

Most innovations were the direct result of a customer request for advanced grease with better thermal properties. AOS is always pleased to honor such a request and most formulas can be modified according to your OEM specifications. If necessary, we will work with you to customize a thermal grease.

Silicone vs. Non Silicone

AOS developed the first non-silicone thermal grease because silicone-based grease has the tendency to separate and migrate, potentially contaminating electronic packages. After several thermal cycles silicone compound can dry out, causing cracking and separation as in the picture shown here. As air gaps form components lose interface surface contact, resulting in a loss of thermal conduction. Non-Silicone Compounds stay put and in place for the full operational life of your hardware.
