Towards Eco-Friendly PVC Thermal Stabilization with a Multi-StabilizingMechanism via Calcium Maleate, Calcium Stearate, and Zinc StearateHybrid

This study proposes a multi-mechanism thermal stabilizer system (zinc stearate, calcium stearate,calcium maleate) to replace lead-based stabilizers in PVC. Adjusting the component ratios,Compound No. ۲ improved thermal stability by ۳۰%, and Compound No. ۳ by ۵۰%, compared topure PVC. Experimental data shows the stabilizer's synergistic interactions effectively inhibit PVCthermal degradation pathways like dehydrochlorination and discoloration. Developing lead-freestabilizers addresses environmental and health concerns. Systematic exploration of synergisticsystems provides insights for advanced PVC compositions with enhanced thermal resistance andsustainability.
