Aktisil
The Aktisil grades, i.e. activated Sillitins, are produced by modifying the surface of Neuburg Siliceous Earth with chemicals, specifically with selected silanes. Several different grades have been developed in order to always ensure optimum coupling between filler and polymer.
In comparison with untreated Neuburg Siliceous Earth, the Aktisil grades, through improved wetting by the polymer, offer manifold benefits in different fields of application:
- Increased tensile strength
- Tensile strength maximum at higher filler loadings
- Higher tensile moduli
- Lower tension and compression set
- Lower abrasion loss
- Improved fluid resistance
- Consistently high electrical resistivity, also upon water immersion
