Thermally conductive silicone is also commonly called thermally conductive RTV adhesive, which can be cured at room temperature and has certain bonding properties. Thermally conductive silicone is a type of silicone rubber and is a one-component room temperature vulcanized liquid rubber.Once exposed to the air, the silane monomer condenses, forming a network structure, cross-linking the system, not melting and dissolving, elastic, rubbery, and bonding the object. And once cured, it is difficult to separate the bonded objects.
Thermal silicone grease is a kind of heat-transfer medium. It is an ester-like polymer composite material which is based on silicone (polysiloxane polymer) and is added with various auxiliary materials and synthesized through a special process.It is a white or gray heat-conductive and insulating viscous object. The material has a certain viscosity and no obvious graininess.Non-toxic, odorless, non-corrosive, stable in chemical and physical properties, and excellent in thermal conductivity, electrical insulation, high temperature resistance, aging resistance and water resistance. Under normal circumstances, thermal silicone grease is insoluble in water, is not easily oxidized, and has certain lubricity and electrical insulation.
Both of them have the same thermal conductivity and insulation, are thermal interface materials.
The difference between the two is:
Thermally Conductive Silicone: Viscosity (hard to remove once it is stuck, so most of the time it is used where only one-time bonding is required), translucent, high-temperature dissolution (viscous liquid), solidification (exposure) at low temperatures, not melting And dissolved, elastic.
Thermal silicone grease (thermal paste): Adsorbent, non-sticky, paste-like semi-liquid, non-volatile, non-curing (low temperature is not thick, not thin at high temperatures).
Through the above introduction, I believe that everyone must have a clear understanding of thermal silica gel and thermal grease. Later, when you purchase the product, you can quickly know which thermal material is suitable for your product.
