Starch Modification / Molecular Properties

Starch derivatives for adhesives and binders

Native starches already have adhesive properties above their swelling and gelatinization temperatures. But because of their instable viscosity they are only suitable as an adhesive if storage stability isn’t required. Process reliability, plant productivity and product quality can be influenced through chemical derivatization with low degrees of substitution. One focus of our work is to optimize starch adhesives in the manufacturing of corrugated cardboard so that traditional stein hall adhesives can be replaced by dispersion adhesives.
