Epoxidized soybean oil - Epoxidized soybean oil

…Polyvinyl chloride decomposes when exposed to light or heat, generating hydrogen chloride, and epoxy compounds are used as plasticizers that capture this hydrogen chloride. Epoxidized soybean oil is used in particular for food and medical materials. Thus, the performance of a plasticizer requires that it (1) mixes well with the polymer (compatibility), (2) is not toxic to living organisms (safety), (3) does not evaporate (heat resistance), (4) does not lose its properties as a plasticizer even at low temperatures (cold resistance), and (5) does not escape from the polymer (non-migration, non-bleed-out). …
