Abstract: By replacing the 10 php (parts per hundred polyvinylchloride) DOP plasticizer with the epoxidized linseed oil (ELO) in polyvinylchloride (PVC) Processing, a slight increase in tensile properties was observed. The water, 30 wt.% acetic acid, 10 wt.% KOH solution, sunflower oil and rt-hexane were used as media to evaluate the leaching characteristic. The sample weight increased slightly after soaking in water, 30 wt.% acetic solution and decreased slightly in 10 wt.% KOH solution, reduced sharply and strongly in sunflower oil and /i-hexane. The presence of ELO has shown an improvement in migration, vocalization characteristics and thermal property of PVC. The positive effect of ELO as a secondary plasticizer was most evident after 72 hours of soaking in H-hexane because the shore A hardness of ELO plasticized PVC sample increased by 12 % while PVC sample without ELO was blistered and its shore A hardness could not be measured. The scanning electron microscopy was used to study the morphology of fractured surface the samples after immersing in /;-hexane.
