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.
