Rheological, thermal and mechanical characterization of PBAT/PCL/Stearates blends

The slow degradation and the high environmental impact caused by inappropriate disposal of polymer products are main factors prompting scientists to either substitute conventional polymers biodegradable ones or enhance biodegradation short-lived products, particularly those used in packaging. Polymer blends is one alternative solutions found improve mechanical properties accelerate after disposal. This work investigates effect incorporating different metallic stearates (Zn Mg) on rheological, thermal characteristics 75PBAT/25PCL processed an internal laboratory mixer. results torque rheometry suggest during processing potentialized with incorporation, while that DSC indicated crystallinity increased incorporation additives. TG data showed a reduction stability systems containing stearates. Incorporation resulted strongly thermally degraded systems. Adding up 0.25% magnesium stearate blend leads material combines maintenance improvement combined higher decomposition.
