Are thermal silica gel and thermal grease the same product?

Many customers are often confused about the difference between thermal silica and thermal grease, and do not know how to choose when buying? Friends who have not been in this industry believe that thermal silica and thermal grease are the same product, but they are not. Although there is only one word difference, the difference is a thousand miles away. Although thermal silica and thermal grease are both thermally conductive The material, but the performance is still different, let's distinguish the difference between thermal silica and thermal grease.

The performance of thermal grease and thermal silica gel are similar, and the manufacturing process is similar, except that a viscous substance is added to the formula to make it have better bonding performance.

Thermally conductive silica gel is a one-component dealcoholization type room temperature curing silicone rubber. The condensation reaction of moisture in the air releases low molecules to cause cross-linking and curing. It can be cured into an elastomer with higher hardness in a short time. It has the functions of cooling and bonding electronic devices. After curing, it is closely adhered to its contact surface to reduce thermal resistance, thereby facilitating the heat conduction between the heat source and the surrounding heat sink, main board, metal shell and outer shell. Thermally conductive silicone products have the advantages of high thermal conductivity, good insulation performance, and ease of use. Thermally conductive silicone products have good adhesion to metals including copper, aluminum, stainless steel, etc., and the curing form is dealcoholized, which is suitable for metal and non-metal surfaces. Does not produce corrosion.

And what we usually call thermally conductive silicone grease is in the form of a grease paste, has no adhesive properties, and does not dry out. It is produced with a special formula and uses metal oxides and organosiloxanes with good thermal conductivity and insulation. Compounded. Thermal grease has excellent thermal conductivity, good electrical insulation, wide operating temperature (working temperature -50°C to 200°C), stable heat dissipation, low consistency and good construction performance. Thermal grease is non-toxic , Non-corrosive, tasteless, non-drying, insoluble.

Through the introduction of the above content, I believe everyone has a certain understanding of the difference between thermally conductive silicone and thermally conductive silicone grease. Although silicone grease and silicone are only literally different, and both are thermally conductive materials, they are completely different. Two things. Relatively speaking, the application range of silicone grease is wider, and it is almost suitable for the needs of any electronic product heat dissipation conditions; and the thermal conductive silicone is difficult to remove once it is attached, so it is mostly used in some occasions where only one-time bonding is required.
