ULTRASIL® 7000 GR

ULTRASIL® 7000 GR is a precipitated silica for use as a reinforcement filler in the rubber industry.

ULTRASIL® 7000 GR is a mechanically compacted granulate. On account of the granulation process it leads to less dust development during mixing.

ULTRASIL® 7000 GR is an easily dispersible and highly reinforcing silica which was 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®, Si 266® or VP Si 363. Additionally, the use of diethylene glycol, triethanolamine or other alkaline accelerators might be necessary in order to achieve optimum rubber-technical data.

Application fields are: Tires, mechanical rubber goods.

Packaging and Storage

For details regarding our packaging options for this product, please contact us.

Our silica products are inert and extremely stable chemically. However, due to their high specific surface area, they can absorb moisture and volatile organic compounds from the surrounding atmosphere. Therefore, we recommend storing the products in sealed containers in a dry, cool place, and removed from volatile organic substances. Even if a product is stored under these conditions, after a longer period it can still pick up ambient moisture over time, which could lead to its exceeding the specified moisture content. For this reason, our recommended use-by date is 24 months after date of m
