About
Silica-based functional filler developed for elastomers. It is suitable for pressure-less cured extruded products, sponge rubber, roller coverings, bright and white rubber compounds. It is used in cable sheaths and cable insulation, pharmaceutical stoppers, molded products and gaskets. It is activated, calcined grade produced by modifying the surface with amino functional silane. Shelf life: 2 years.
Benefits:
- Prevents mold fouling, improves resistance to liquids
- Exhibits improved vulcanization using amine crosslinkers (BIIR) and bisphenolic crosslinkers (FKM)
- Increases tensile strength, abrasion resistance and modulus
- Shows maximum tensile strength at higher filler loading
- Offers low sieve residues, moisture, tension and compression set
- Provides high brightness, color-neutrality, electrical- and chemical resistance
- Delivers dispersion behavior, good aging, extrusion and rheological properties

About hoffmann mineral
Hoffmann Mineral, located in Neuberg, Germany, produces functional filler Neuburg Siliceous Earth, which is a natural combination of corpuscular Neuburg Silica and lamellar kaolinite: a loose mixture impossible to separate by physical methods. As a result of natural aging, the silica portion exhibits a round grain shape and consists of aggregated cryptocristalline primary particles of about 200 nm diameter. Such a unique structure is responsible for a relatively high specific surface area and oil absorption, which result, besides rheological activity, also in a whole range of application properties.
