white silicone heat sink compound thermal grease for PCB
SFY-635 is a white silicone heat sink compound thermal paste heavily filled with heat conductive metal oxides. The incorporation of high efficient heat-conductive metal oxides promotes high thermal conuctivity, low bleeding and high temperature stability.
Characteristics
1,Has excellent thermal conductivity
2, Up to 175 degree centigrade, SFY-650 is very stable to changes of temperature.
3. RoHS and REACH compliance.
Uses
Mainly used in electronic components of the heat transfer medium, can enhance their work efficiency. Such as: high-power transistors (especially the plastic tube), SCR components, thermostat contacts between the diode and the substrate (aluminum, copper) contacts the heat transfer medium gap Department, rectifiers, radiator.
