AEROSIL® fumed silica for cable gels

Cable gels are oil-based filling compounds which are used in fiber optic cables to protect the sensitive optical fibers.


Cable Gels are used to isolate sensitive optical fibers from external forces and to protect the fibers from moisture. Additionally it enables the gel to stay where it is placed in the application as well as forming a seal to keep out contaminants like dust, dirt and water.

Benefits of AEROSIL® fumed silica as thickener:
  • Rheological properties (e.g. viscosity, yield point, structure stability, thick recovery)

  • Improvement of water and acid resistance

  • Low (-40°C) to High (80°C) temperature range

  • Gel separation characteristic / Prevent settling

  • Improvement of the Thixotropic behavior

  • Moisture resistance

  • Environmentally safe / low-emission

  • Color: White/Translucent

  • High chemical purity

  • Electrically non-conductive / no influence on the dielectric properties of the common oils
