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 minitype and ultra-thin equipments with excellent manufacturability and practicability.With wide range of thickness,it is widely used in electronic products.
Soft and compressible
Thermal impedance is small
Low pressure application
Very good electrical insulation and temperature resistance
