  • Which plasticizers are used in the production of flexible PVC materials?
  • However, with a glass transition temperature (T g) of about 90 °C [ 4 ], the production of flexible PVC materials requires the use of external plasticizers (e.g, phthalates, citrates, and others) [ 3, 5 ].
  • How to choose a general-purpose plasticizer for PVC?
  • While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
  • 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 .
  • What are the different types of plasticizers?
  • There are two main groups of plasticizers: Internal plasticizers are part of the PVC molecule (where a second monomer is copolymerized into the polymer structure). Internal plasticizers have generally too narrow of a temperature processing range to be useful. This is why external plasticizers are the most important commercially.
  • What are natural product type plasticizers?
  • Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
  • What are the different types of plasticizers used for polymer modification?
  • Several chemical families of plasticizers are used for polymer modification. Among them, the most common are: Phthalate Esters – Produced by esterification of phthalic anhydride or phthalic acid. Obtained by the oxidation of orthoxylene or naphthalene. Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate.
