ULTRASIL® 7000 GR  德固赛7000GR白炭黑

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.

Safety & Handling

Information concerning the safety of this product is listed in the corresponding Safety Data Sheet, which will be sent with the first delivery or upon updating. Such information is also ***ailable from Evonik Industries AG, Product Safety Department, E-MAIL: sds-im@. We recommend to read carefully the safety data sheet prior to the use of our product.

Packaging and Storage

For details regarding our packaging opti*** 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 conditi***, 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 manufacture. Product more than 24 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
