ULTRASIL® VN 3 as a precipitated silica is used as a reinforcing filler in all kind of rubber applications. Properties and applications: With its high reinforcing potential ULTRASIL® VN 3 imparts to rubber compounds particularly 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 can provide vulcanizates of excellent transparency. CAS No: 112926-00-8 and 7631-86-9 Information provided by Evonik |
