ULTRASIL® 360
- Chemical Name
- Silica gel pptd. cryst.-free
- Chemical Family
- Silica
ULTRASIL® 360 is a semi-active precipitated silica with a very low N2 surface area of approximately 55m²/g. It is particularly well-suited for use in extrusion, injection molding, calendaring mixtures, and soft roll processes. This product is easy to process, even at high filler loadings. When used in vulcanized rubber goods, ULTRASIL® 360 leads to lower residual deformation and excellent dynamic characteristics.

- Packaging Information
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 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.
