Natural Gypsum: Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common. We are enlisted amongst the topmost INatural Gypsum Importers and Exporters from India. Applications: Gypsum has many industrial applications in its raw or Calcined forms, especially in the building and construction industries. Uses of Raw Gypsum are principally as: - a retarder for Portland cement - a fertilizer or soil conditioner - mineral filler - oxidizing agent in glass manufacture or other industrial applications. Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement. Imported Gypsum from Iran: Natural Gypsum is one of the most superior qualities and consistent material available for Import and Export. Natural Gypsum has adequate whiteness, high purity as well as it is low in cost which makes it absolutely feasible for white cements as well as Plaster Of Paris manufacturing and for the Cement Industry all together. One more important quality that distinguishes Natural Gypsum from others is its hardness which is less as compared to other sources and allows different industries to easily grind the same for processing into final product which in turn results in to reduced power consumption for manufacturing industries.

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.

Kaolin: Kaolin uses are multiple and diverse. Kaolin are used as functional filler, extender, ceramic raw material and pigment because of its whiteness and fine particle size. Kaolin also hold importance as raw material in refractory applications, concrete, rubber and fiber glass manufacturing. We, as a Kaolin Exporter welcome any size of international orders from Middle East and other countries. Applications: Paper: Kaolin used as a coating pigment and as a filler to replace fiber. It possesses desirable optical properties. Concrete: Kaolin helps to improve strength and durability of concrete. When added to concrete mix, reacts with free lime released during cement hydration to produce additional cementitious material, resulting in an improved high performance concrete. Plastics : Kaolin is widely used as filler in the plastics industry because of its inert chemical nature and its unique size, shape and structure. Agriculture : It is used as a carrier and diluent in fertilizers, pesticides and related products. It is suitable as carrier because it aides the retention of the formulations on the plant. Rubber : It is commonly used as functional filler in rubber applications. While Kaolin improves overall performance for Rubber in general, different types of white pigment play specific roles in rubber application. Paint : Kaolin used as an extender in paints. It reduces the amount of expensive pigment such as Titanium Dioxide. It assists with desirable rheological properties that help maintain proper dispersion and provide bulk to the product. Ceramic : Kaolin improves whiteness and brightness of ceramic body. Good plasticity, good shrinkage, low water absorption and casting rate are also very important properties of kaolin.
