Cable Gel Applications

Use of AEROSILĀ® fumed silica for cable gels gives excellent performance when it comes to shear-thinning, providing quick recovery and the gel does not require heat to be applied. AEROSILĀ® fumed silica improves properties of oil-based filling compounds for wire and cables to protect fibers (e. g. optical fibers) as it:

  • Supports to isolate sensitive optical fi bers from external forces
  • Protects the fi bers from moisture
  • Provides thickening to help the gel to stay where it is placed
  • Helps to form a seal to keep out contaminants like dust, dirt and water
  • Is non-conductive / does not negatively infl uence di-electrical properties
Lubricating Grease Applications

The use of AEROSILĀ® fumed silica is recommended for lubricating greases used in industrial applications, automotive, electrical as well as food grade.

  • Electrical - Offers rheology control as well as water resistance.
  • Industrial - Offers rheology control as well as excellent oxidation resistance against water and chemicals.
  • Automotive - Offers rheology control as well as excellent oxidation resistance against water and chemicals.
  • Food - Hydrophilic AEROSILĀ® are generally recognized as safe (GRAS; direct food contact). Offers rheology control as well as water resistance
AEROSILĀ® Fumed Silica in Lubricating Greases

AEROSILĀ® fumed silica helps to build a stable matrix to increase viscosity and suppress oil separation in lubricating greases. It can be used in the following systems:

  • In non-soap greases, used in high-temperature applications up to 230Ā° C as well as for extreme-pressure and multipurpose greases.
  • In soap greases, thickened by fatty acid soaps of lithium, calcium, sodium or aluminum, AEROSILĀ® fumed silica can be used to further improve the performance of the lubricating grease.
  • Hydrophilic fumed silica provides optimized thickening effects in non-polar oils.
  • Hydrophobic fumed silica provides viscosity control and increased water repellency in semi-polar to polar oils.
  • The surface area of the silica and the volume fraction of the silica in the fi nal mass play a role in the long term storage and heat stability.
