Bentonite Powder
Bentonite powder is a naturally occurring absorbent clay primarily composed of montmorillonite, a type of smectite clay mineral. It exhibits excellent swelling and water absorption properties, making it highly versatile in industrial and commercial applications. Bentonite forms a gel-like substance when mixed with water, which imparts viscosity and plasticity. It is used extensively for its binding, sealing, and adsorptive characteristics. Its fine powder form allows for easy incorporation in various processes including drilling, foundry, cosmetics, pharmaceuticals, and agriculture.
Binder
A binder is a broad category of substances—organic or inorganic—used to hold different materials together in a cohesive mass. Common binders include natural polymers (starch, cellulose derivatives, proteins), synthetic resins (PVA, acrylics, phenolics), and inorganic binders (clays, cement, lime). They are essential in industries such as pharmaceuticals, construction, coatings, ceramics, adhesives, and printing, where they provide structural integrity, adhesion, and controlled release properties.
Hycryl
Hycryl is a specialized acrylic copolymer resin designed primarily for industrial and cosmetic applications. It appears as a white to off-white powder or granules with excellent film-forming, adhesive, and thickening properties. Known for its compatibility with a wide range of solvents and plasticizers, Hycryl 77 provides excellent clarity, flexibility, and durability in coatings, adhesives, and personal care formulations.

Hydrocarbon Resins
Hydrocarbon Resins C5 And C9 Petroleum Resins are synthetic petroleum-derived resins produced through the polymerization of C5 (pentene) and C9 (nonene) fraction monomers. These resins appear as pale yellow to amber solid materials, usually in pellet or flake form, characterized by tackifying and adhesive properties. C5 resins are derived from aliphatic hydrocarbons, while C9 resins originate from aromatic hydrocarbons. Often blended, these resins provide a balance of hardness, tackiness, and compatibility with various polymers. Widely used as tackifiers, binders, and modifiers, C5 & C9 hydrocarbon resins enhance performance in adhesives, coatings, rubber compounding, and more.
