Many customers often can't tell the difference between thermally conductive silicone and thermally conductive silicone grease, and don't know how to choose when purchasing? Friends who have no contact with this industry may believe that thermally conductive silicone and thermally conductive silicone grease are the same product, but they are not. , Although there is only a difference of one word, but the difference is a thousand miles away. Although thermally conductive silicone and thermally conductive silicone grease are both thermally conductive materials, their functions are still different. The following is a manufacturer of thermally conductive silicone sheets to differentiate between thermally conductive silicone and thermal conductivity. The difference between silicone grease.

Thermal grease and thermal silica have similar functions, and the manufacturing process is similar, except that a viscous substance is added to the formula to make it have a better bonding function.

Thermally conductive silica gel sheet is a one-component dealcoholized room temperature curing silicone rubber. The moisture in the air produces a condensation reaction to release low molecules to cause cross-linking and curing. It can be cured into a high hardness elastomer in a short time. It has the functions of cooling and bonding electronic devices. After curing, it is closely attached to its contact surface to reduce thermal resistance, which is beneficial to the heat conduction between the heat source and its surrounding heat sinks, motherboards, metal shells and outer casings. Thermally conductive silicone products have the advantages of high thermal conductivity, good insulation and easy to use. Thermally conductive silicone products have excellent adhesion to metals including copper, aluminum, stainless steel and other metals. Does not produce corrosion. And what we generally call thermal grease is a kind of grease paste, which has no bonding function and will not dry. It is produced with a special formula and uses metal oxides and organosiloxane with excellent thermal conductivity and insulation. compound. Thermal grease has excellent thermal conductivity, excellent electrical insulation, wide operating temperature (working temperature -50 ℃ ~ 200 ℃), stable heat dissipation, low consistency and excellent construction performance, thermal grease is non-toxic , Non-corrosive, odorless, non-drying, insoluble.

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