                                Silicon Dioxide

                                (anticaking agent)

                                1.Chemical Name: Silicon Dioxide

                                2.Formula: SiO2

                                3.CAS: 7631-86-9

                                4.Molecular weight:60.08

                                5.Properties:

                                It is a silica with a high absorption capacity and used as a flow and anticaking agent in many applications as well as a special-purpose ingredient for mechanical graphics papers. In plant protection, this product is recommended as a carrier in solid formulations such as wettable powders (WP) and water-dispersible granules (WG) if grinding is to be avoided.
