摘要：
In this work, we have evaluated the curing process of a natural-based plasticizer, epoxidized linseed oil, as a possible alternative to phthalate substitution for polyvinyl chloride. Several curing times ranging from 6 to 14 min at different isothermal curing temperatures in the 140-220 degrees C range have been selected. The effects of the curing process (in terms of time and temperature) have been determined by mechanical tests, color measurements, and microstructure characterization. The obtained results show that optimum overall properties are obtained for curing times of 1012 min at 200 degrees C or 8 min at 220 degrees C, which are typical values of industrial processing of vinyl plastisols.
