ULTRASIL® VN 2 GR as a precipitated silica is used as a reinforcing filler in all kind of rubber applications.
Scope of Application
ULTRASIL® VN 2 GR is a mechanically compacted granulate. On account of the granulation process it leads to less dust development during mixing.
Due to its lower specific surface area, ULTRASIL® VN 2 GR has a slightly lower reinforcing potential compared to ULTRASIL® VN 3. It imparts to rubber compounds high Shore hardness, tensile strength, tear resistance and abrasion resistance and offers advantages concerning compound viscosity and processing. In order to achieve optimum rubber-technical data the addition of activators like glycols, amines or other alkaline accelerators is necessary.
Application fields are: Tires, mechanical rubber goods.
