Orisil fumed silica is packaged in paper multi-ply valve bags, which ensure reliable storage of the product during the warranty period. The bag is labelled with the grade, batch number, date of manufacture and net weight. The weight of the bag with undensed fumed silica is 10 kg and with densed silica is 20 kg. Material is shipped on wooden pallets or in bulk. Pallet size is 114x114cm. Our pallets comply with international standards ISPM-15 and CP-3. Palletized bags are secured with polypropylene tape and covered with stretch wrap. It is possible to pack the product in special polypropylene Big-Bags with a net weight of 150-200 kg for undensed material. The size of the Big-Bag is 110x110x200 cm.
About the product
Today Orisil company is the leading producer of pyrogenic silica in Eastern Europe. Orisil fumed silica is a highly dispersed amorphous silicon dioxide (SiO2) produced by flame hydrolysis of silicon tetrachloride (SiCl4) or other chlorosilanes. The production is a complex continuous high technology process. The process of flame hydrolysis is carried out in a gas phase of air-hydrogen flame at a temperature of 1100-1400 ° C: The chemical reaction is accompanied by release of significant amount of heat, which is recovered and utilized. Hydrogen chloride (HCl) is the only by-product in this process. Changes in concentration of reactants, flame temperature and reaction rate cause significant alteration in size and structure of the primary particles. The size of the primary particles determines the specific surface area of Orisil fumed silica dictating the grade of the final product.
