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.
Corn Starch Industrial Grade Uses
Primary UsesÂ
Paper Industry
- Acts as a surface sizing agent to improve paper strength, gloss, and printability.
- Used in coating formulations to enhance smoothness and reduce porosity.
- Serves as a binding agent in recycled paper production to improve fiber bonding.
Adhesives & Binders
- Used in manufacturing starch-based adhesives for corrugated cardboard, paper bags, and labels.
- Serves as a binder in particleboard, fiberboard, and plywood production.
Textile Industry
- Employed as a sizing agent to strengthen yarns during weaving, improving fabric quality and reducing breakage.
- Used in finishing processes for fabric stiffening and texture enhancement.
Bioplastics & Packaging
- Used as a biodegradable polymer base for producing eco-friendly packaging materials and films.
- Serves as a filler and functional additive in bioplastic blends to improve mechanical properties.
Secondary UsesÂ
Pharmaceuticals
- Acts as an excipient in tablet formulation, primarily as a disintegrant and binder (non-food grade applications).
Construction
- Used as a dust control agent in construction sites and as a binder in gypsum and cement formulations.
Cosmetics & Personal Care
- Utilized as a thickener and absorbent in powders and creams (industrial formulations).
Agriculture
Used as a carrier for pesticides and fertilizers in controlled release formulations.
