Modified starch is a functional industrial additive made from natural starch through physical, chemical, or biological modification processes. It effectively solves the shortcomings of native starch, such as easy aging, unstable viscosity, poor temperature resistance, insensitivity to acids and alkalis, and weak shear resistance, possessing stronger binding, film-forming, thickening, suspension stabilization, water retention, and rheology regulation capabilities. With its stable performance, high cost-effectiveness, environmental friendliness, and customizability, Nourisi modified starch has been widely used in various industrial fields and is an indispensable basic raw material in modern industrial production.
In the papermaking industry, modified starch is one of the core additives. Oxidized starch, cationic starch, and esterified starch are mainly used for surface sizing, internal sizing, and wet-end retention and filtration aids in papermaking. They can significantly improve paper smoothness, surface strength, burst strength, and water resistance, reduce dusting and linting, while increasing the retention rate of fine fibers and fillers, effectively reducing papermaking production costs and improving the overall quality of paper products.
In the textile industry, modified starch is mainly used as a sizing agent. Compared to native starch, it has more stable viscosity, better penetration, more flexible film formation, and is easier to desizing. During high-speed weaving, it can effectively wrap and protect yarns, reduce breakage and pilling, and improve fabric smoothness and weaving efficiency. It is the most economical, mature, and green sizing agent product for textile sizing.
In the building materials and coatings industry, pregelatinized starch and cross-linked starch are widely used in water-based coatings, putty powders, dry mortars, construction adhesives, and other products. They possess excellent thickening, water-retention, anti-sagging, and lubricating properties, improving application flowability, enhancing coating uniformity, and simultaneously strengthening the bonding strength, adhesion, and durability of building materials.
In addition, modified starch is widely used in environmental water treatment, biodegradable packaging, adhesives, daily chemicals, and the rubber and plastics industries. It can be used as a flocculant, filler stabilizer, rheology modifier, and bio-based raw material, aligning with the industrial development trend of low carbon, environmental protection, and biodegradability.
Nourisi modified starch boasts adjustable properties, wide applicability, controllable costs, and is safe and environmentally friendly. It can meet complex industrial conditions such as high temperature, high speed, acid and alkali, and high shear, making it an important functional raw material for improving quality, reducing costs, and increasing efficiency across various industries.
