In this study, the recycling of poly(butylene adipate-co-terephthalate)(PBAT) was simulated through repeated processing by injection molding. Twelve consecutive recycling steps were carried out by repeated grinding and reprocessing of the PBAT. The effect of recycling was evaluated by tensile testing and hardness measurements. The results indicate that the yield strength, tensile modulus, and hardness remained unchanged, while the elongation at break exhibited a slight increase.
Kivonat
A kutatás keretében fröccsöntéssel történő többszöri feldolgozás útján szimuláltuk a poli(butilén-adipát-ko-tereftalát) (PBAT) újrahasznosítását. A PBAT-on tizenkét egymást követő újrahasznosítási ciklust hajtottunk végre az alapanyag ismételt ledarálása és újrafeldolgozása révén, majd szakítóvizsgálattal és keménységméréssel vizsgáltuk az újrahasznosítás hatását. Az eredmények alapján a folyási feszültség, a húzó rugalmassági modulus és keménység nem változott, míg a nyúlás kismértékben megnőtt.
