AKTISIL PF 216

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 waterIncreases tensile strength, modulus, dynamic load capacity, resistance to liquidsOffers high chemical resistance, low abrasion loss, tensile and compression setShows maximum tensile strength combined with a higher level of fillingExhibits good dispersion, extrusion, rheology, heat conductivity and aging properties
