Natural Graphite

Natural Graphite is an excellent Thermal Interface Material to remove air gaps between components and heatsinks. It is very flexible and can be manufactured into any gasket shape or size and with the higher thermal conductivity of 300W/mK it is ideal for, among others, LED Lighting applications.

Features and Benefits...

  • High efficiency heat transfer: Thermal conductivity 300W/mK: Flexible diaphragm, conversion into any shape (minimum hole size 1.0mm diameter).
  • Light weight: density is 1.5-2.1g/cm3 (between 1/3-3/4 of aluminum and equivalent to 1/5-1/4 of copper).
  • Low resistance: can be used for electromagnetic shielding.
  • Adhesive option available

Applications...

  • Communication equipment and peripheral equipment;
  • Computers, Tablet Computers, Smart phones, Intelligent terminals, High power LED applications etc.
