Corn Starch Industrial Grade
Original price was: $ 1.67.$ 1.55Current price is: $ 1.55.
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.
Corn Starch Industrial Grade

Calcium Carbonate Uncoated
Calcium Carbonate Uncoated is a naturally occurring mineral compound composed primarily of calcium, carbon, and oxygen with the chemical formula CaCO₃. It appears as a fine white powder or granules, widely used as a filler, pigment, and functional additive across various industries. The uncoated form means the calcium carbonate particles are not surface-treated, retaining their natural properties. It is valued for its high brightness, whiteness, and excellent compressibility. Uncoated calcium carbonate is used to enhance opacity, improve processing, and reduce costs in plastics, paints, coatings, adhesives, rubber, paper, and construction materials.
Coated Calcium Carbonate
Coated Calcium Carbonate is a fine, white, odorless powder consisting of naturally occurring ground calcium carbonate (CaCO₃) treated with a surface coating—typically stearic acid or other fatty acids—to enhance compatibility with non-polar matrices. This coating improves dispersion in plastic and rubber formulations, reduces moisture pickup, and enhances the physical properties of the final product. Compared to uncoated grades, coated calcium carbonate offers better hydrophobicity, improved flow properties, and stronger interfacial bonding in polymeric systems. It is widely used in plastics, rubber, paints, sealants, adhesives, paper, and more.
Corn Starch Food Grade
Corn Starch Food Grade is a fine, white, powdery carbohydrate extracted from the endosperm of corn kernels (Zea mays). It is a natural, tasteless, and odorless polysaccharide composed primarily of amylose and amylopectin. Corn starch is widely used as a thickening, stabilizing, and binding agent in food products due to its excellent gelatinization properties. It serves as a gluten-free alternative to wheat flour in many culinary and industrial applications. Corn starch is valued for its versatility, digestibility, and neutral flavor profile, making it a staple ingredient in both home cooking and commercial food production.
Kaolin
Kaolin is a naturally occurring, fine white clay mineral primarily composed of kaolinite. It features a soft, powdery texture and excellent absorbency.
