Effect of Sunflower Oil on the Mechanical Permanence and the Thermal Properties of Poly (Vinyl Chloride)

Hexyl phthalate Di-(-2-ethyl) (DEHP) is a conventional plasticizing for polyvinyl chloride (PVC) was partially replaced by organic plasticizer. Epoxidised sunflower oil (ESO) was epoxeded and characterized. The partial replacement of DEHP with epoxidized sunflower oil (ESO) and its mixtures have been analyzed, Testing of the hot air aging and mechanical testing of the dynamic stability of the color indicated ESO may be used as a secondary plasticizer, less volatile for PVC compared with the study of phthalate of Di (2-ethylhexyl) (DEHP) shows that the migration of DEHP may be substantially reduced without affecting the useful mechanical properties. An increase in the content of ESO has increased mechanical properties, while the composition with the oxirane oxygen hight ESO showed the best permanence propreties.
