    A GUIDE TO UNDERSTANDING AND MIXING THICKENERS

    Thickeners come from both natural and synthetic sources. Naturally occurring polymers comprised of polysaccharide or amino acid building blocks and are generally watersoluble. Common examples are starch cellulose alginate egg yolk agar arrowroot carageenan collagen gelatin guar gum pectin and xanthan gum.

  • Preparation of Associative Polyurethane Thickener and Its

    The CMC of nonionic associative polyurethane thickeners is very low through the measurement of three different ABA blocktype associative PU thickeners (Table 2) and the formation of the micelles is the main reason of thickening viscosity increase and changes in the rheological properties when the shear stress is low. So the thickening effect is apparent when the concentration is controlled in a

    Polyurethane thickeners show a very good resistance to hydrolysis. In acid emulsions it may be necessary to dilute the thickener before addition (i.e. 10% solution) to prevent coagulation of the emulsion. 5.6 Influence of solvents The properties of polyurethane thickeners can be influenced by solvents depending on type and quantity.
