ULTRASIL® 7000 GR
Product Information
ULTRASIL® 7000 GR is a mechanically compacted granulate which is an easily dispersible and highly reinforcing silica. On account of the granulation process it leads to less dust development during mixing.

Scope of application:
It is especially developed for application in low rolling resistant passenger car tire tread compounds. It imparts to tread compounds high abrasion resistance combined with excellent rolling resistance and wet traction. To achieve these properties it is necessary to use ULTRASIL® 7000 GR and a bifunctional organosilane, such as Si 69®, Si 75® or Si 266®. Additionally the use of diethylene glycol, triethanolamine or other alkaline accelerators might be necessary in order to achieve optimum rubber-technical data.
