Thermal grease is an indispensable heat dissipation auxiliary material in electrical appliance manufacturing. Unlike adhesives, this product does not harden after application and requires no waiting period before subsequent assembly processes can begin. To fully unleash its thermal conductivity, in addition to the quality of the product itself, proper application is equally crucial.
I. Durability of Thermal Grease Performance
The duration of thermal conductivity retention depends primarily on the quality of the thermal grease raw materials. High-end thermal grease can maintain stable heat dissipation capabilities over a long period; inferior products will show a significant decrease in thermal conductivity after a period of use, and in severe cases, complete failure of heat dissipation. It is recommended to prioritize high-quality thermal grease, such as the TENSAN brand, which has deep expertise in thermal material research and development and can provide customized thermal grease application solutions suitable for various industry heat dissipation scenarios, covering new energy, military, medical, aerospace, shipbuilding, consumer electronics, automotive, precision instruments, switching power supplies, and rail transportation.
II. Are there any restrictions on the applicable electrical appliances for thermal grease?
Thermal grease is non-corrosive to metals, non-toxic, and poses no health hazards. It only needs to be filled between the heat-generating components and the heat dissipation structure of the equipment to achieve efficient heat conduction. There are no restrictions on its use in general electrical heat dissipation scenarios; it can be used in any equipment with heat dissipation requirements.
III. Standard Application Points
1. Control the coating thickness: A thicker coating does not necessarily mean better thermal conductivity. Provided that the gaps between components are completely filled, a thinner coating results in higher heat conduction efficiency and better heat dissipation performance.
2. Avoid contact areas: Do not apply the grease around exposed conductive contacts such as relays and terminals to prevent silicone oil contamination and circuit malfunctions.
IV. Product Storage and Shelf Life Instructions
Thermal grease is a non-toxic and non-hazardous chemical. It should be stored in a well-ventilated, dry environment, away from children. The standard shelf life of unopened, original products is 12 months; it is recommended to use it within this period. After the shelf life has expired, the internal filler is prone to delamination, and the thermal conductivity will decrease significantly. Continued use in production is not recommended.
