TIMCAL ENSACO™ 250G Conductive Carbon Black Compounds
Categories: Carbon; Carbon Black; Other Engineering Material; Additive/Filler for Polymer

Material Notes: ENSACO™ & SUPER P™ conductive carbon blacks have a high to very high void volume allowing the retention of a carbon network at low to very low filler content. The void volume can originate from the interstices between the carbon black particle due to their complex arrangement and from the porosity.

PROPERTIES:

  • High Structure / Low Surface Area
  • Soft flakes
  • Low oxygen content
  • High purity
  • High graphiticity
PERFORMANCE
  • Electrical conductivity
  • Excellent dispersion
  • Low viscosity increase
  • Low cure inhibition
  • Easy mixing and processing
  • Some thermal conductivity
  • Meets the most stringent purity requirements
FINAL APPLICATIONS: Automotive fuel hoses, transmission belts, conveyor belts, power cable accessories, thin membranes with high shock resistance, conductive profiles and seals, antistatic flooring, rollers, roller covering… Suitable for all rubber types including silicones and fluoroelastomers
