ULTRASIL® VN 2
- Chemical Name
- Silica gel pptd. cryst.-free
- Chemical Family
- Silica
ULTRASIL® VN 2 is primarily used at high filler loadings in PCT (passenger car tire) tread compounds without any loss in processing behavior. This silica is particularly well-suited for use in combination with bifunctional organosilanes, which help to optimize wet and winter properties. Additionally, high static moduli are observed with and without additional organosilanes. This is why ULTRASIL® VN 2 is also widely used in other mechanical rubber goods. It is available in both powder and granulated silica forms.
