Thermoplastic Starch (TPS)

Starch is the main component of the biopolymers belonging to the polysaccharide group. Starch is a bio-polymer that is derived from renewal resources such as corn, potato, tuber or other plants. Because the starch the does not melt or flow during processing it cannot be processed like a thermoplastic material. So, a plasticizer (glycerol) is commonly added under high shear mixing which converts the starch to a thermoplastic starch allowing it to be processed like other thermoplastics.
