  • Which plasticizers are used in flexible PVC products?
  • The conventional petroleum-derived plasticizers used in many flexible PVC products are phthalate esters (also known as “phthalates”). The literature reported that phthalates represent more than 85% of world plasticizers production, of which 90% is annually used in PVC manufacturing .
  • How does plasticization affect spectral properties of PVC?
  • Plasticization of PVC results in a weakening of the intensity of both these bands . Moreover, the changes in spectral features of the plasticizer molecule can be followed to evaluate its interactions with PVC.
  • How does an efficient plasticizer interact with PVC?
  • An efficient plasticizer interacts with PVC and breaks the extended network of chain-to-chain dipole-induced dipole forces present originally in a polymer that is observed as an attenuation of a signal coming from the covalent bonds. The stronger the interactions, the more prominent the shift of particular peaks to the lower wavenumber .
  • How will global demand for plasticizers affect the plasticizer market?
  • Continued global demand for flexible PVC will lead to continued growth for plasticizers. Demand for most downstream plasticizer markets is greatly influenced by general economic conditions. As a result, demand for plasticizers largely follows the patterns of the leading world economies.
  • What is the role of plasticizers in PVC processing?
  • Their major function is to impart flexibility and workability of the resin. Plasticizers play an important role in the processing of PVC by: They decrease the processing temperature, the melt viscosity while improving filler and pigment dispersion .
  • Is PVC a good plasticizer?
  • Thermal stability studies showed that PVC blends with HPGs were more stable (exhibiting higher onset temperature values on TGA curves) than samples with DEHP. A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance.
