Thermal gap filler has excellent flexibility insulation, compressibility and natural surface viscosity performances. It used to fill the gap and realize the heat transfer between the heating parts and cooling parts. It also has insulation and shock mitigation effects. Meanwhile, it can satisfy the design requirements for mini type and ultra-thin equipment with excellent manufacturability and practicability. With wide range of thickness, it is widely used in electronic products.
Features and benefits
- Soft, excellent compression performance
- Low thermal resistance
- Being recognized as UL94 V-0
- Viscous surface
- Excellent insulation performance and thermal resistance
- Being to work under low pressure
