What is the difference between thermally conductive silicone resin and thermally conductive silicone grease?

When buying thermally conductive products, many people confuse thermally conductive silica gel with thermally conductive silicone grease. The two names are similar, but they are not the same product, and their use is quite different. Therefore, how to separate thermal silica and thermal grease?

Thermally conductive silicone rubber is a one-component dealcoholized room temperature curing silicone rubber, which has the function of cooling and bonding electronic components. It can be cured into a high-hardness elastomer in a short time. After vulcanization, the contact surface is closely attached to reduce the thermal resistance, which is beneficial to the heat transfer of the surrounding heat sink, main board, metal shell and shell. This series of products has the advantages of high thermal conductivity, good insulation performance, and convenient use. It has good bonding properties with metals including copper, aluminum, stainless steel, etc., and has a dealcoholization curing method that does not corrode metal and non-metal surfaces.

Also known as thermal conductive silicone grease, also known as silicone oil, it is a kind of grease, non-adhesive, non-drying. It is produced with a special formula. It uses a special formula to compound metal oxides and organosiloxanes. It has good thermal conductivity and insulation. sex. The product has excellent thermal conductivity, good electrical insulation, high operating temperature (working temperature -50°C ~ 250°C), good stability in use, low consistency, excellent construction performance, non-toxic, non-corrosive, odorless, non-dry, and insoluble , Insoluble.

The characteristics are different.

1. Thermal conductive silicone grease: has high thermal conductivity, excellent thermal conductivity, good electrical insulation (only used for thermal conductive silicone grease insulation), wide use temperature, good use stability, low consistency and good construction performance .

2. Thermally conductive silica gel: Small molecules are released due to the condensation reaction of moisture in the air, and it is vulcanized into a high-performance elastomer. It has excellent resistance to cold and heat alternating properties, aging resistance and electrical insulation properties. And has excellent moisture-proof, anti-vibration, anti-corona, anti-leakage and chemical medium properties.

Different uses.

1. Thermal conductive silicone grease: used for heat conduction and heat dissipation of electronic components such as power amplifiers, transistors, CPUs, etc., so as to ensure the stability of electrical performance of electronic instruments and meters.

2. Thermally conductive silica gel: the contact surface between various electronic products, electrical equipment (power tube, thyristor, electric heating pile, etc.) and heat sink (heat sink, radiator, heat sink, heat sink, housing, etc.) , Play the role of heat transfer medium and moisture-proof, dust-proof, dust-proof and shockproof.
