Borax Decahydrate
Borax Decahydrate, also known as sodium tetraborate decahydrate, is a naturally occurring mineral and an important inorganic compound. It appears as colorless or white crystalline granules or powder with a salty, alkaline taste. This compound is widely used in detergents, cosmetics, glass manufacturing, agriculture, and various industrial applications due to its excellent buffering, emulsifying, and antiseptic properties. The “decahydrate” indicates that each molecule of borax contains ten water molecules bound in its crystal structure, contributing to its crystalline appearance and physical properties.
Borax Pentahydrate
Borax Pentahydrate (sodium tetraborate pentahydrate) is an inorganic compound and a hydrated form of borax. It typically appears as colorless to white crystalline granules or powder. This compound contains five molecules of water of crystallization per formula unit, distinguishing it from other borax hydrates such as the decahydrate form. Borax Pentahydrate is widely used across industries including detergents, glass production, agriculture, and cosmetics, valued for its buffering capacity, emulsification, and antiseptic properties. It is soluble in water and exhibits alkaline properties in aqueous solution.

Known for its higher bulk density compared to regular grades, this filler is widely used in applications requiring enhanced weight, opacity, and strength. It is commonly employed as a functional filler and extender in industries such as plastics, paints, coatings, adhesives, rubber, paper, and construction materials. Its inert nature, whiteness, and particle size distribution make it suitable for improving mechanical properties and surface finish, while also offering cost efficiency by replacing more expensive raw materials.
CMC Sodium (Carboxymethyl Cellulose Sodium)
CMC Sodium, or Carboxymethyl Cellulose Sodium, is a water-soluble anionic cellulose ether derived from natural cellulose. It appears as a white to off-white, odorless, tasteless powder or granule. Known for its excellent thickening, stabilizing, emulsifying, and water-retention properties, CMC is widely used in food, pharmaceutical, personal care, industrial, and detergent applications. It functions by modifying the rheological properties of solutions and suspensions, offering control over viscosity and flow. Its biocompatibility, non-toxicity, and biodegradability make it suitable for both human use and environmentally friendly formulations.
Corn Starch Industrial Grade
Corn Starch Industrial Grade is a finely milled, white powder derived from the endosperm of maize (Zea mays). Unlike food-grade starch, industrial grade is tailored for non-food applications where its thickening, adhesive, and film-forming properties are exploited. It consists primarily of amylose and amylopectin polysaccharides and is valued for its biodegradability, renewability, and cost-effectiveness. Industrial corn starch is used extensively as a raw material or functional additive across a wide variety of manufacturing processes, including paper, textiles, adhesives, and packaging industries.
Master Air
Master Air is a high-performance air release agent used primarily in concrete and construction applications. It facilitates the release of entrapped air bubbles from fresh concrete mixtures, improving workability, surface finish, and durability. This additive enhances the homogeneity of concrete by reducing air voids that can weaken the structure. Master Air is suitable for use in ready-mix concrete, precast elements, and other cementitious materials, contributing to improved mechanical properties and longevity of the final product.
Medium Binder
Medium Binder is a versatile adhesive and binding agent formulated to enhance cohesion, strength, and durability in various industrial and construction applications.
