Applications & Uses

Applications

• Silicone rubber
• Sealants
• Thermoplastics

Cable Gel Applications

Use of MultiTech Rheology Modifier A 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 Rheology Modifier A 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 Rheology Modifier A 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 MultiTech Rheology Modifier A are generally recognized as safe (GRAS; direct food contact). Offers rheology control as well as water resistance

MultiTech Rheology Modifier A Fumed Silica in Lubricating Greases

MultiTech Rheology Modifier A 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 Rheology Modifier A 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.
