Abstract: PVC is generally degraded during processing, producing several undesirable effects. In this work, mixtures of calcium and/or zinc stearates and epoxidized soybean oil are used as stabilizers. In addition, to improve overall stability, D-sorbitol or triphenyl phosphite were added as costabilizers. The formulation composition was systematically varied considering the following parameters: a) presence of epoxidized soybean oil, b) CaSt2/ZnSt2 ratio and, c) presence and type of costabilizer. Thermal stability was followed during isothermal heating by determining: a) the accumulation rate of some conjugated polyenes and, b) the changes in the tensile properties.
