Two Component Thermal Conductive Gel
Two component thermal conductive gel is a preformed thermal gap filling material, which can be solidifified at room temperature or high temperature to form a flflexible and thermally conductive elastomer, which is formed with the shape of the structure. After curing, it is equivalent to the thermal conductive silicone gasket. It mainly meets the requirements of low pressure and high compression modulus. It can realize automatic dispensing production with high effiffifficiency. It has good contact with electronic products, increases effffective contact area and reduces contact thermal resistance. It can automatically fifill the gap and compress infifinitely. It is suitable for heat dissipation modules or electronic components with large thickness variation.
Features
- High thermal conductivity, low thermal resistance, good wettability.
- Lower assembly stress, easy to operate.
- High reliability, after curing, it is equivalent to thermal pad, no volatilization.
- Automatic dispensing adjustment of any thickness.
- After curing, the modulus is low, which greatly reduces the stress caused by thermal expansion and the damage caused by vibration.
Applications
- Network terminal /5g mobile phone communication.
- New energy battery.
- Automotive electronic application equipment.
- Electronic medical / power equipment.
- Between fragile components and housing.
