White Dextrine (CAS 9004-53-9) is a modified starch, a starch-derived polymer obtained through partial hydrolysis under acidic conditions, supplied as a white powder in Technical Grade and Food Grade and used mainly as a binder for paper, cardboard, textile sizing and construction materials. It is characterized by its white color and excellent binding properties.
The product offers a high Purity Level and consistent viscosity, making it a primary adhesive for paper and cardboard industries. Its Film-Forming Ability ensures smooth application in textile sizing and specialized coating formulations.
In the construction sector, it acts as a stabilizer and water-retention agent in gypsum and mortar mixes. It is a vital Specialty Chemical for the production of abrasive wheels and as a binder in the foundry industry.
