4 Point Probe Sheet Resistance Method

  • Significant improvement
    in conductivity

    (2.4 times @130℃, 3.7 times @150℃)

  • Viscosity slightly increases
    but does not pose any issues

    Great compatibility,
    favorable for pasting

  • Anticipate increased effects
    by incorporating more Graphene

  • Offers remarkable benefits
    for the application of
    conductive plastic masterbatch
