Product Recommendation | Fehonda Thermal Grease

Release time：

Thermal Grease

As a medium for transferring heat, thermal grease has excellent thermal conductivity, good lubricity and electrical insulation; it also has good high and low temperature resistance; it has low viscosity and good construction performance.

Its low thermal resistance makes it suitable for high heat generation and close fitting scenarios. It has the lowest thickness of thermal conductive products, and can quickly transfer the heat of the equipment to achieve good temperature control, thereby extending the service life of electronic components and improving their reliability.

Users can choose the appropriate product according to the actual application, clean the surface to be coated, remove oil and impurities, and evenly coat the surface with silicone grease. Coating is carried out by spot coating, brush coating, screen printing, etc.
