Product Advantages


Two-part Thermally Conductive Gap Filler

A two-component, solvent-free, thermally conductive filling material. Its basic material is a silicone system. It is suitable for filling the gap between electronic heating components and radiators. Its typical applications include automotive power batteries, new energy battery packs, communication base stations, etc.


  • High flow rate for efficient distribution

  • Good coating performance ensures good filling of gaps in larger areas

  • Good interface wetting ability, low interface thermal resistance

  • Extremely strong resistance to mechanical shock or vibration

  • High thermal conductivity: 2.0 ~ 12.0  W/m•K


Thermal Gel

One-component high-performance silicone thermal conductive gel, including pre-cured/post-cured gel, has low risk of oil separation, can be stored at low temperature/normal temperature, and is specially designed for applications requiring high thermal conductivity interface materials.


  • High thermal conductivity

  • Easy to use

  • Good surface wetting ability

  • High reliability, good thermal cycle resistance

  • Extremely low modulus and stress

  • High thermal conductivity: 2.0 ~ 15.0  W/m•K


Thermal Grease

One-component thermal grease is non-flowable and contains a highly filled compound that is easy to remove from the substrate. Typical applications include heat sinks, memory and thermal management of chips, power transistors and CPUs.


  • High temperature resistance

  • Low BLT, low thermal contact resistance

  • Good thermal cycle reliability

  • Low modulus and mechanical stress

  • Can automatically dispensing/screen printing/squeegee coating

  • High thermal conductivity: 2.0 ~ 8.0  W/m•K
