ULTRASIL® VN 3 GR as a precipitated silica is used as a reinforcing filler in all kind of rubber applications.
Scope of Application
ULTRASIL® VN 3 GR is a mechanically compacted granulate. On account of the granulation process it leads to less dust development during mixing.
ULTRASIL® VN 3 GR has a high reinforcing potential and imparts to rubber compounds high Shore hardness, tensile strength, tear resistance and abrasion resistance. In order to achieve optimum rubber-technical data the addition of activators like glycols, amines or other alkaline accelerators is necessary. On account of the higher surface area ULTRASIL® VN 3 GR can provide vulcanizates of excellent transparency.
Application fields are: Tires, mechanical rubber goods, cables and shoe soles of all kinds.
