    From an industrial point of view, the use of new nontoxic and biodegradable plasticizers coming from natural resources is an interesting alternative to traditional plasticizers based on phthalates. In this study, two types of epoxidized fatty acids esters (EFAE) with different molecular weights have been used in order to produce flexible PVC with low toxicity. Different amounts of EFAE 201 and 401 have been considered in this study. Mechanical and thermal properties have been determined and morphology of fracture surface has been studied by scanning electron microscopy.This work was supported by the "Ministerio de Ciencia e Innovacion" [Grant number IPT-310000-2010-37] and the "Universitat Politecnica de Valencia" [Grant number PAID 06-10 Ref: 003-300].Fenollar Gimeno, OÁ.; García Sanoguera, D.; Sánchez Nacher, L.; Boronat Vitoria, T.; López Martínez, J.; Balart Gimeno, RA.
