Abstract
ECO-FRIENDLY FOAMING PROCESS OF POLYBUTYLENE ADIPATE TEREPHTALATE(PBAT), POLYBUTYLENE SUCCINATE TEREPHTALATE (PBST) AND THEIR BLENDS WITH THERMOPLASTIC STARCH (TPS) - CUP Master: F53C24000940006
Polybutylene adipate-co-terephthalate (PBAT) and polybutylene succinate-co-terephthalate (PBST) are biodegradable polyesters, obtainable with raw material from renewable sources. They can be used in the production of foams for the manufacture of trays for the food packaging industry. PBAT and PBST also have a rheology that is not functional to the foaming process. As polyesters, they have many features in common with PET that make managing the foaming process very complex. Therefore, the research project aims to demonstrate the manufacturing process of foams in PBAT, PBST and their blends with TPS by acting on the design of materials, on the modification of the rheology of resins by reactive extrusion, on the prototyping of foamed items on a laboratory scale, on the validation of the functional properties of such items. A comparative study of the life cycle of the foams obtained will also be developed.
