Thermal Grease / Paste
Thermal grease / paste has excellent heat conductive, diversified operations and reliability stable performance, has good wettability on the surface of copper and aluminum.Due to the lower viscosity can sufficient wetting contact surface to form the low interface thermal resistance, which can rapidly transfer heat energy to the radiating heat device, high efficiency of heat transfer.Thermal grease / paste has good electrical insulation and tightly paste, low consistency and easy to use.
Applications:
Between semiconductor and cooling fins, CPU and radiator, between power resistor and the base, power supply LED, LCD, PDP etc.
Specifications:
30g/ syringe, 1kg/tube, 5kg/tube,10kg/tube.
Storage conditions:
Seal stored in a cool and dry place.
Feature :
1,Thermal impedance 0.016-0.06ºC-in/W, extremely low thermal resistance and good heat transfer, thoroughly wetting contact surface, improving the heat dissipation effect, safety and environmental protection, it passed the RoHS certification.
2,Low oil yield, low volatilization rate;
3,High thermal conductivity, excellent electrical insulation and stability, good performance to resist high and low temperature;
4, Water resistance, not curing, metal material on contact without corrosion (copper, aluminum, steel)
5, Extremely low volatilization loss, low melting, not dry, good material adaptability, use temperature range(-50~+250ºC);
6,Non-toxic, odorless, no corrosion, stable in chemical physics properties.
