Moisture or contaminants, such as dust and dirt, negatively impact the sensitive fibers in these cables. Cable gels or oil-based fillers are therefore all the more important. They protect the quality and durability of fiber-optic cables. Products with a correspondingly permanent effect are therefore required. Both hydrophilic and hydrophobic silica can help here: When used as thickeners, they can control the viscosity and optimize oil separation.
In addition, our AEROSIL® fumed silica products improve various parameters, such as mechanical stability and heat resistance. In short: Enhance the quality of your cable gels with Evonik’s diverse range of products and receive products with the best possible material composition. This also applies in particular for submarine cables, overland cables or cables with high material strength. Our highly experienced specialists with many years of experience will support you in all aspects.
Advantages of the silica for cable gels
- Optimum rheology control: Set the viscosity of your cable gels and oil-based fillers
- Flow limit and thixotropic effects can be achieved optimized in the best possible way
- They also increase mechanical stability
- They optimize oil separation in cable gels and oil-based fillers
