CS-872 Silicone Rubber Series

It is mainly composed of adhesive and thermal conductive particles. Before gluing, it is a paste like mixture, and after gluing, it solidifies under certain time and conditions. Our thermal conductive silicone is a single component room temperature vulcanized silicone rubber with good adhesive properties. Room temperature curing The curing conditions are simple Repackable, with a curing thickness generally between 4-5mm. But it is sensitive to the surface state of the heat sink, and the bonding strength of devices or heat sinks with surface contamination is weak. Strict on-site process control.

1. Environmentally friendly, non-toxic, non corrosive, in compliance with ROHS and REACH directives.

2. Excellent adhesion, fixation, insulation, sealing, moisture resistance, shock resistance, and aging resistance.

3. It can firmly adhere to different materials such as metal, glass, ceramics, plastics, etc.

4. The cured silicone rubber has good electrical insulation performance, high and low temperature resistance, waterproof and moisture-proof, aging resistance, and long-term rubber elasticity.
