THE THERMAL ANALYSIS OF POLYSTYRENE FOUNDRY MODEL

Abstract

The article presents the results of thermogravimetric (TG) investigations of a polystyrene foundry model. The study was conducted for three polystyrenes - Owipian (Syntos Oświęcim), copolymer PS and PSX (France). Next, TG analysis was performed for the prepared PS foundry model and the results obtained show that PS fully degrades in the temperature range of 321-395°C. Finally, kinetics of gasification and intensity of gas volatilization were investigated for PS foundry model.
