  • Is epoxidized soybean oil a plasticizer for PVC?
  • Epoxidized soybean oil is one of the additives in the PVC gasket. It serves as a plasticizer and a scavenger for hydrochloric acid released when the PVC degrades thermally, e.g. when the gasket is applied to the lid and food product undergoes sterilization. ESBO is also used in PVC cling films for wrapping foods and toys.
  • What is ring opening of epoxidized soybean oil?
  • Biopolyol synthesis via ring-opening of epoxidized soybean。It is noteworthy that during the ring-opening process of epoxidized soybean oils (ESO), catalysts play a crucial role in achieving desirable biopolyol products with a high epoxy ring-opening rate and a great hydroxyl number.
  • How is epoxidized soybean oil made?
  • There are two main production methods for epoxidized soybean oil: solvent method and solvent-free method. The specific production methods include peroxyformic acid oxidation method, ion exchange resin catalysis method, aluminum sulfate catalysis method, peroxycarboxylic acid oxidation method and phase transfer catalytic oxidation method.
  • What are bio-based plasticisers for polyvinyl chloride (PVC)?
  • Novel bio-based plasticisers for polyvinyl chloride (PVC) are a significant and growing area of interest. These compounds aim to replace toxic and petro- chemical additives in commonly used plastic products. Plasticisers can com- prise as much as 50% of the total mass of the PVC product.

  • Are bio-based plasticisers suitable for PVC compounding?
  • epoxide groups per molecule). These products were evaluated as potential bio-based plasticisers for PVC compounding, with the aim of matching the performance of the petrochemical plasti- cizer DOP. mPEG-ESBO showed the greatest plasticising behavior as measured by Tg suppression and tensile prop- erties.
  • Is epoxidized soybean oil toxic?
  • Ingestion of sufficient amounts of epoxidized soybean oil may cause gastrointestinal upset and may produce a laxative effect. Severe overexposure may cause coma or respiratory failure. Prolonged skin contact may cause mild irritation or dermatitis.
