Urea and formamide as a mixed plasticizer for thermoplastic

Abstract. Urea and formamide were used as a mixed plasticizer for preparing the thermoplastic wheat Flour (TPF) by a single screw extruder. Wheat flour granules were proved to transfer to a continuous phase by Scanning Electron Microscope (SEM). Rheology analysis illustrated that during the thermoplastic processing both the extruder screw speed

During the thermoplastic process, water contained in starch and added plasticizers play an indispensable role ( Hulleman, Janssen, & Feil, 1998; Wang, Shogren, & Carriere, 2000 ), because the plasticizers can form the hydrogen bonds with starch, take the place of the strong action between hydroxyl groups of starch molecules, and make starch
