Exploring the Potential of Zinc Maleate/Magnesium Carbonate for ThermalStabilization of Polyvinyl Chloride

This study explores the use of zinc maleate (ZnMa) and magnesium carbonate (MgCO۳) as ecofriendlythermal stabilizers for unplasticized PVC (UPVC). Traditional stabilizers, like lead salts, areeffective but toxic, necessitating safer alternatives. We evaluated the thermal stability of UPVCformulations containing ZnMa, MgCO۳, and their combinations with calcium stearate (CaSt۲) andzinc stearate (ZnSt۲). Discoloration tests revealed that ZnMa and MgCO۳ significantly improveUPVC stability. The ZnMa/CaSt۲ combination outperformed ZnSt۲/CaSt۲, and theZnMa/MgCO۳/CaSt۲ blend showed the highest stability, highlighting their potential as effective, saferstabilizers for PVC.
