  • What is epoxidised soybean oil (ESBO)?
  • Epoxidised soybean oil (ESBO) is a commercially available bio-based plasticizer that is typically used at lower levels than traditional phthalates in PVC compounds because it does not show equivalent performance to existing phthalate plasticisers. Four derivatives of ESBO have been synthesized through reaction at the epoxide rings.
  • Does dibenzoylmethane stabilize epoxidized soybean oil (ESBO) Plasticized PVC?
  • The present work focuses on the development of different epoxidized soybean oil (ESBO) plasticized PVC formulations in the presence of calcium/zinc stearates and beta-diketone stabilizer such as dibenzoylmethane (DBM). The DBM which has dual property of a UV stabilizer and heat stabilizer was varied from 0 to 10 phr.
  • Is dibenzoylmethane a UV stabilizer & heat stabilizer for epoxidized soybean oil?
  • Hence, the present work focused on development of different epoxidized soybean oil (ESBO) plasticized PVC formulations in the presence of zinc and calcium stearates and beta-diketone stabilizer such as dibenzoylmethane (DBM) which has dual property of a UV stabilizer and heat stabilizer.
  • Can soybean oil be used as a co-stabilizer for PVC?
  • Epoxidized soybean oil indicated the excellent properties as a co-stabilizer for PVC when used in combination with the Ca/Zn stearates. The ternary system helped to improve plasticization effect and thermal stability of PVC compositions. Fly ash filled PVC system showed better thermal stabilization effect.
  • How does Esbo affect PVC decomposition?
  • The effect of ESBO on PVC decomposition is observ- able in the Step 1 mass loss. PVC-DOP and PVC-DOTP lose 73.9 and 73.7% of the total sample mass in this step, while PVC-ESBO loses only 54.1%. This is likely to be a combination of the reduction in dehydrochlorination as described, as well as the lower volatility of ESBO.
  • How does Esbo decompose benzene?
  • gated polyenes and hydrochloric acid, followed by cycli- sation to form benzene and other aromatic compounds.32 The epoxide rings in ESBO react with chloride ions that are released during PVC decomposition.33 This slows the degradation as the hydrochloric acid produced by the PVC decomposition acts as a catalyst for this decom- position.
