LCK -10 Silicon Pad

LCK-10 is a kind of high performance insulating material coated with silicone rubber based on polyimide film, which has excellent puncture resistance and excellent thermal conductivity. LCK-10 is specially designed as a substitute for ceramic insulators such as beryllium oxide, boron nitride and bauxite. Ceramic insulator is more expensive and easy to damage. In contrast, lck-10 is not easy to damage and has lower cost.


  • High thermal conductivity and low thermal resistance.
  • It can withstand high voltage up to 8kv.
  • No stickiness on both sides, easy to operate and disassemble.
  • It can replace ceramic insulator.


  • Automotive electronic heating module.
  • Heating power device.
  • Power supply module.
  • Home appliances / motor control.
  • Military electronics / thermal semiconductor.
