  • What are secondary plasticizers?
  • Secondary plasticizers contain groups which are less polar. They demonstrate limited solubility and compatibility with PVC, that is why they are often used in mixtures with primary plasticizers. Such mixtures show a reduced tendency to migration, but increased strength at reduced temperatures and resistance to precipitation.
  • What is primary plasticizer?
  • If the plasticizer induces softness and elongation when added to the polymer, it is called primary plasticizer.
  • What are plasticizers?
  • Plasticizers are intermediate chemical products whose properties determine greatly the performance of the products which they are added. It is estimated that in the search for plasticizers to modify rigid polymers, more than 30,000 substances have been tested.
  • Which plasticizers are compatible with PVC?
  • One of the most common divisions is made on the basis of their solvation properties and their compatibility with PVC, where they are further divided into primary and secondary plasticizers. Primary plasticizers are compatible with PVC and those containing polar groups are characterized by high solvation capabilities.
  • 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.
  • What percentage of plasticizers are used other than PVC?
  • Polymers other than PVC account for less than 10% of the current worldwide plasticizer usage. While the combination of PVC polymer, plasticizers, and other additives can yield an extensive range of flexible products with varying performance characteristics, plasticizer usage with other polymers does not produce the same level of versatility.
