WT5921-86 Thermal Gel
WT5921-86 is made of silicone resin as a base material, added with thermally conductive fillers and additives at a certain ratio, and is a sludge processed by a special process. It has excellent high and low temperature resistance, excellent weather resistance, radiation resistance and excellent dielectric properties.
▶ Features
● No chemical reaction required
● Suitable for irregular gap filling
● Excellent chemical and mechanical stability
● It can be reworked and reused to reduce waste
● High thermal conductivity, low thermal resistance
● With extrusion fluidity, adapt to the dispensing process
● No sedimentation, storage at room temperature, convenient storage
● It will not be deformed during static use after molding, and has excellent aging resistance
● Strong plasticity, easy to cooperate with product designs that require large changes in thickness
● Excellent high temperature resistance, excellent weather resistance, radiation resistance and
superior dielectric properties
● With its own adhesiveness, there is no need to use adhesive products that are not helpful to
thermal conductivity to improve its adhesive performance
