Thermal and Mechanical Properties of PVC and PVC-HDPE Blends

Abstract

The objective of this study was to improve the physicochemical properties of mixtures of polymers and PVC-PVC * HDPE * by the addition of stabilizers deferential percentages (2%-5% -10% ). According to the study of mechanics and in general it was found that the mixture containing recycled PVC once has mechanical properties - before and after higher than the other blends (HDPE / recycled PVC).the addition of PE in the blend PVC (50% HDPE 50% PVC) makes a big change in the structure of the polymer PVC (fall gradually properties tensile). The thermal stability of the blend HDPE / recycled PVC increases with the growth percentages of stabilizers. In addition in the same mixture this latter decreases with increasing rate of recycled PVC. The stabilizing 81KA Baeropan the stabilizer is the most recommended rate 2% and improved mechanical properties of PVC resin on the other hand Baeropan MC87-03 altered these properties has rate 10 % and 5%.
