Electrial resistance control technology

  • A products surface resistance can be easily controlled at the specific levels required for ESD control materials through the use of Krefine’s special carbon technology.

  • Krefine can guarantee the surface resistance of its products within the first power of plus or minus 10.

  • Beyond a certain critical special carbon content, the surface resistance of a compound decreases with an increase in the special carbon content to 1010 ohms. 

  • The surface resistance of the compound in the critical content region depends on the resistance of the special carbon.

  • Further increasing the special carbon content beyond the critical content region, results in a very small resistance change versus the higher levels of special carbon.

  • However, when carbon powder or carbon fibers are employed, the surface resistance drops sharply beyond the critical carbon content level to approximately 102 ohm.
