AKTISIL PF 216
Provided by Hoffmann Mineral
About
Silica-based filler developed for elastomers. It is suitable for pressure-less cured extruded products, sponge rubber, cable sheaths, cable insulation, molded products and seals. It is also used in tire components, solid rubber tires, roller coverings, conveyor belts and vibration dampers. It is activated grade produced by modifying the surface with tetrasulfane. Shelf life: 2 years.
Benefits:
- Water-repellent filler, less heat build-up, higher rebound resilience (in SBR)
- Electric insulation resistance remains high and constant after storage in water
- Increases tensile strength, modulus, dynamic load capacity, resistance to liquids
- Offers high chemical resistance, low abrasion loss, tensile and compression set
- Shows maximum tensile strength combined with a higher level of filling
- Exhibits good dispersion, extrusion, rheology, heat conductivity and aging 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.
