Aktifit VM in medium and high voltage cable insulations

Calcined product, vinyl functionalized.

Aktifit VM offers lower moisture content, lower dielectric loss and higher electrical resistivity. 

  • very low sieve residue in ppm range
  • excellent dispersion properties
  • very good extrusion properties
  • high tensile strength
  • avoids mold fouling/deposits on dies caused by filler
  • good resistance to oil, water and acid
  • very high electrical resistivity, even after storage in water
  • very low dielectric loss, even after storage in water, even without additional silane
