HTSX Silicone Heat Transfer Compound Xtra

In Stock

HTSX is a silicone thermal interface material (TIM) which has been developed to perform in more extreme conditions than its sister product HTS. It exhibits extended characteristics to HTS, with higher thermal conductivity, extended operating temperatures and excellent stability with a much-reduced oil bleed.

It is a non-curing thermal paste, making it easy to apply and easy to rework if necessary. It is ideal for use on heatsinks or between components to dissipate heat away from the electronic device and can be used in a wide range of industry applications.
