  • 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).
  • Does polyester plasticizer reduce migration resistance?
  • High degree of branching of polyester plasticizer more effective to reduce migration resistance than low degree of branching of polyester plasticizer. Both the high and lower branching of polyester plasticizer can improve thermal stability of PVC materials compared to DEHP.
  • 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 .
  • Which plasticizer reduces Young's modulus of PVC?
  • The E ( x) of all plasticized systems converged as the temperature reached 500 K. DBS was the only plasticizer that consistently decreased the Young’s modulus of PVC as well as or better than DEHP ( Figure 4 ). Figure 4. Predicted Young’s modulus for systems of PVC plasticized with DEHP, DBS, DHS, DEA, and 1,4-BDB at temperatures from 150 to 500 K.
  • Which PVC composites are resistant to migration stability?
  • PVC composites modified with SiO 2 @poly (acrylic acid) (PAA) microsphere also shows excellent resistance to migration stability . Fig. 18. SEM micrographs of (a) pure PVC and composites filled with (b) ZnO, (c) TiO2, (d, e) organoclay, and (f) carbon nanotubes. Reproduced from , with permission from Wiley & Sons.
  • Why do flexible PVC products need plasticizers?
  • The properties of flexible PVC products significantly change with addition of plasticizers, such as reduction of the glass transition temperature (Tg) and tensile strength, while elongation will increase, which make PVC change from hard and brittle to flexible, thus greatly expand its application [, , ].
