  • What are alternative plasticizers for polyvinyl chloride (PVC)?
  • Environmental and toxicity concerns dictate replacement of di (2-ethylhexyl) phthalate (DEHP) plasticizer used to impart flexibility and thermal stability to polyvinyl chloride (PVC). Potential alternatives to DEHP in PVC include diheptyl succinate (DHS), diethyl adipate (DEA), 1,4-butanediol dibenzoate (1,4-BDB), and dibutyl sebacate (DBS).
  • Can polymer plasticizer improve thermal stability of PVC materials?
  • Both the high and lower branching of polyester plasticizer can improve thermal stability of PVC materials compared to DEHP. Hyperbranched poly (ε-caprolactone) (PCL) with different lengths of linear segments and different numbers of branches, as the polymer plasticizers, show no migration in volatility, extractability, and exudation tests .
  • Why are plasticizers important?
  • Well-chosen plasticizers can also improve resistance to UV exposure and chemical attack. This contributes to the long-term stability of the polymer. In specific applications, plasticizers can influence the dielectric properties of polymers. This makes them suitable for use in electrical insulating materials.
  • Which plasticizer has the best plasticizing efficiency?
  • It's worth noting that PSCH has the best plasticizing efficiency attributed to the C–Cl bond on the side. According to the similar compatibility principle, except for hydrogen bonding, the existence of C–Cl bond in PSCH increases the compatibility of plasticizer and PVC.
  • Are organic heat stabilizers suitable for PVC?
  • In recent years, environmentally friendly organic heat stabilizers have been prepared and developed for the heat stability of PVC. Wang et al. [ 8] studied tung-oil-derived imide epoxidized esters as a PVC heat stabilizer.
  • What makes a polymer a good plasticizer?
  • It is nowadays established that good plasticization implies secondary bonds, also known as intermolecular forces, with the polymer. The attraction between plasticizer molecules and the polymer must be as strong as the interactions between molecules in the single components to generate an efficient polymer-plasticizer interaction.
