best thermal grease 2020 Manufacturers

Potting adhesives have penetrated into various manufacturing industries and play important roles. However, there are many types of potting glues on the market, and there are also many brands. Users often don’t know how to choose when purchasing. What are the key points for choosing potting glues? What factors should you consider when purchasing? To understand these issues, you need to understand the following.

Thermally conductive silicone pad is a high-performance gap filling thermal conductive material, mainly used for electronic equipment and heat sink or product shell between the transfer interface, with good adhesion, flexibility, compressibility, and excellent thermal conductivity, so that it can completely make the air between the original electronic parts and heat sink in use, to achieve full contact, heat dissipation effect is significantly improved.

Advantages: Silicone potted gel cured after the material is soft, there are solid rubber and silicone gel two forms, can eliminate most of the mechanical stress and play a shock-absorbing protection effect. The chemical properties of physical properties are stable, has good resistance to high and low temperatures, and works for a long time in the range of -50 to 200 degrees C. Excellent weather resistance, outdoor for more than 20 years can still play a better protective role, and not easy to yellow. With excellent electrical performance and insulation capacity, after potted to effectively improve the internal components and line insulation, improve the stability of the use of electronic components. With excellent repair capacity, it is quick and easy to remove sealed components for repair and replacement.

In July 2026, TENSAN released a technical guide on encapsulation compound selection, systematically analyzing the performance differences and selection logic of three major systems—silicone, epoxy, and polyurethane—along with specialty compounds, aiming to help engineers in electronics, new energy, and automotive industries make scientific material choices and drive the evolution of packaging materials toward functional and intelligent solutions.

As an adhesive with good flexibility after curing, flexible sealant has full elasticity and bonding. When used, the flexibility changes before and after curing. After successful pouring, it can be bonded to most materials. After the bonding is completed, a protective layer is formed to securely protect the bonded object from external factors as much as possible

Many users mistakenly believe that the more sealant used, the better the bonding effect and strength. Therefore, they intentionally overmix the sealant, attempting to improve bonding performance by increasing the amount. However, this approach is incorrect and can cause various problems during actual construction.
