Applications & Uses

Applications

• HTV- and LSR (Liquid Silicone Rubber)
• Cable compounds and unsaturated polyester resins
• Adhesives and sealants

Cable Gel Applications

Use of MultiTech MultiFunctional J 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. MultiTech MultiFunctional J 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 MultiTech MultiFunctional J fumed silica is recommended for lubricating greases used in industrial applications, automotive, electrical as well as food grade.

Electrical

• High thixotropic effect
• High temperature stability
• Dielectric properties

Industrial

• High thixotropic eff ect
• High temperature stability
• Wear resistance
• Extreme pressure resistance

Automotive

• High thixotropic eff ect
• High temperature stability
• Wear resistance
• Reduced friction

Food - Hydrophilic MultiTech MultiFunctional J are generally recognized as safe (GRAS; direct food contact)

• High thixotropic effect
• High temperature stability
• Wear resistance

MultiTech MultiFunctional J Fumed Silica in Lubricating Greases

MultiTech MultiFunctional J 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 230° C as well as for extreme-pressure and multipurpose greases.
• In soap greases, thickened by fatty acid soaps of lithium, calcium, sodium or aluminum, MultiTech MultiFunctional J fumed silica can be used to further improve the performance of the lubricating grease.
• Hydrophilic fumed silica provides optimized thickening eff ects 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.

Technical Details & Test Data

AEROSIL® Fumed Silica

• AEROSIL® fumed silica is a highly dispersed, amorphous, very pure silica manufactured by high-temperature hydrolysis of silicon tetrachloride in an oxyhydrogen gas flame. The primary particles formed in the AEROSIL® process are virtually spherical and free of pores.
• During the formation of the primary particles, aggregates are formed which further accumu- late into agglomerates. Under shear, these agglomerates can be returned back into smaller aggregates.
• Siloxane and silanol groups are found on the surface of the AEROSIL® particles. This latter type of functional group in particular is responsible for the hydrophilic behavior of untreated AEROSIL®. Figure shows the surface groups of hydrophilic AEROSIL® grades.

Surface groups of hydrophilic AEROSIL® grades.

The hydrophobic nature of after treated AEROSIL® grades compared with AEROSIL® 300 can be illustrated by means of moisture adsorption in increasingly humid conditions. Figure below shows the corresponding isotherms.
