  • Which plasticizers are used in PVC?
  • Over 90% of the plasticizers used in thermoplastic polymers are used in PVC. The plasticized polymer market and the plasticized PVC market are largely one and the same although some plasticizer is also used in acrylic polymers, polyurethanes, polystyrene even polyolefins. Some of the major end uses are discussed below.
  • 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.
  • Can phthalate plasticizers be used in Plasticized PVC?
  • For example, the use of phthalate plasticizers in plasticized PVC is neither prohibited in the US (federal and state legislation) nor the EU in any plasticized PVC product. We have already discussed recent regulatory status w.r.t phthalate plasticizers in child care articles. There are also federal regulations (not laws) for plasticizers.
  • What phosphate plasticizers are used for PVC?
  • Some phosphate plasticizers are also used to improve UV light (outdoor weatherability). They are not typically used as primary plasticizers for PVC. Triaryl and alkyl diaryl phosphates are the most important category of flame-retardant phosphate plasticizers used with PVC.
  • Are plasticizers compatible with polymers?
  • They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear. A secondary plasticizer is one that typically cannot be used as the sole plasticizer in a plasticized polymer.
  • Why are epoxy plasticizers used in PVC?
  • The presence of an epoxy group helps these plasticizers to improve heat stability of the manufactured PVC articles. At higher concentrations epoxy plasticizers sometimes develop incompatibility with PVC. Vegetable oil derivatives are the most widely used natural product type plasticizers.
