This product is wetted with water, can be dispersed in water, is a white, odorless, amorphous inorganic chemical products.Fumed silica, molecular formula: SiO2 white fluffy powder, porous, non-toxic tasteless non-polluting, high temperature. At the same time it has a chemically inert and special thixotropic properties can significantly improve the tensile strength of rubber, tear resistance and abrasion resistance, improved rubber strength is increased several times. Liquid systems, adhesives, polymers, rheology and thixotropy control, used as anti-settling, thickening, anti-sagging reinforcing additives, HCR and RTV-2K silicone rubber, can be used to regulate the free flow and as an anti-caking agent to improve powder properties, and so on. Fumed silica will send in handy in many printing inks, such as letterpress printing, gravure printing. It controls the flow to avoid gelling rate as to bring smeared, and thus bring perfect clarity.

Natural Silica (chemical name for the mineral quartz and a synonym for silicon dioxide) Silica is a compound of the elements silicon and oxygen. It is not chemically combined with other elements. When the basic structure of the molecule is a pattern that is repeated and symmetrical, the silica is considered to be "crystalline." Silica is considered to be amorphous if the molecule lacks crystalline structure. In this brochure, the term silica is used to mean crystalline silica (or crystalline silica's most common form, quartz). Used in manufacture of special steels and cast iron, aluminum alloys, glass and refractory materials, ceramics, abrasives, water filtration, component of hydraulic cements, filler in cosmetics, pharmaceuticals, paper, insecticides, rubber reinforcing agent - especially for high adhesion to textiles, anti-caking agent in foods, flatting agent in paints, thermal insulator. Fused silica is used as an ablative material in rocket engines, spacecraft, silica fibers used in reinforced plastics. Available in Micro silica, Fused Silica, Amorphous Silica, Precipitated silica, Quartz powder different mesh sizes and fine powder as per requirement. Packing: Standard 25kg.

Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.
