Boric Acid
Boric Acid, chemically known as hydrogen borate or boracic acid, is a weak, monobasic Lewis acid of boron. It appears as a white, crystalline powder or granules that are odorless and slightly soluble in water. Boric Acid is commonly used in antiseptics, insecticides, flame retardants, and as a buffering agent in various industrial and pharmaceutical applications. Due to its mild antiseptic and antifungal properties, it is often used in ophthalmic, dermatologic, and other personal care formulations. It also plays a key role in glass and ceramics manufacturing as well as in agriculture.
Calcium Carbonate Light
Calcium Carbonate Light is a finely ground, low bulk density natural mineral composed primarily of calcium carbonate (CaCO₃). Compared to standard grades, it has a lower density and larger particle size distribution, making it suitable for applications where light weight and high brightness are important. This form is extensively used as a filler and extender in industries such as plastics, paints, rubber, paper, adhesives, and construction materials to improve opacity, brightness, and texture, while maintaining low weight and cost efficiency. Its chemical inertness and whiteness provide functional and aesthetic advantages across formulations.
Calcium Chloride Dihydrate
Calcium Chloride Dihydrate (CaCl₂·2H₂O) is a hydrated form of calcium chloride, appearing as white crystalline granules or flakes containing two molecules of water of crystallization. It is highly soluble in water and exhibits strong hygroscopic and deliquescent properties. This compound is widely used in industrial, pharmaceutical, food, and agricultural sectors due to its moisture absorption, de-icing, dust control, and calcium supplementation capabilities. Compared to anhydrous calcium chloride, the dihydrate form has lower hygroscopicity but is easier to handle and store.
Calcium Nitrite
Calcium Nitrite is an inorganic compound commonly supplied as a white crystalline powder or granules. It serves primarily as a corrosion inhibitor in reinforced concrete structures, protecting steel reinforcement from rust and prolonging structural lifespan. Calcium nitrite is also used in various industrial processes as an oxidizing agent and preservative. Due to its high solubility in water and strong oxidizing properties, it effectively prevents chloride-induced corrosion and improves concrete durability.
Caustic Soda Flakes
Caustic Soda Flakes, also known as Sodium Hydroxide Flakes (NaOH), are a highly alkaline, white, solid substance that is crystalline and flaky in form. Produced by evaporating aqueous sodium hydroxide solutions, these flakes are highly soluble in water and exhibit strong corrosive properties. Caustic Soda Flakes are widely used in a variety of industrial, chemical, and manufacturing processes due to their strong alkalinity, ability to saponify fats, and effectiveness in pH adjustment. Their high purity and ease of handling in flake form make them suitable for use in chemical synthesis, pulp and paper production, water treatment, and detergent manufacturing.
Caustic Soda Micropearls
Caustic Soda Micropearls are small, spherical, solid particles of sodium hydroxide (NaOH) produced through specialized prilling or pelletizing techniques. They offer excellent flowability, high purity, and uniform size distribution, making them ideal for precise dosing and handling in industrial and chemical processes. The micropearls form is preferred in applications where dust control, ease of transport, and controlled dissolution rates are critical. Caustic Soda Micropearls exhibit strong alkalinity, are highly soluble in water with an exothermic reaction, and are widely used across many sectors including chemical manufacturing, water treatment, pulp and paper processing, and detergent production.
Cellulose Ether
Cellulose ether refers to a group of chemically modified cellulose derivatives where hydroxyl groups on the cellulose backbone are substituted with ether groups such as methyl, hydroxyethyl, or carboxymethyl groups. These modifications improve solubility, viscosity, and film-forming properties while maintaining biodegradability and non-toxicity. Cellulose ethers are white to off-white powders or granules that dissolve in water to form viscous, stable solutions. They are widely used as thickeners, binders, stabilizers, and film formers in industries such as construction, pharmaceuticals, cosmetics, food, and paper.
Master Cast
Master Cast is a high-quality gypsum-based casting material designed for producing precise and durable molds, prototypes, and decorative castings. It offers excellent flowability, rapid setting time, and high strength after curing. Master Cast is widely used in ceramics, sculpture, dentistry, and industrial mold-making applications where fine detail reproduction and surface smoothness are critical.
