  • 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.
  • 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.
  • Which plasticizers are the most important commercially?
  • This is why external plasticizers are the most important commercially. External plasticizers can be monomeric or polymeric. Examples for polymeric plasticizers are EVA, CPE, NBR and terpolymers or polyesters mainly based on adipic acid, diols and mono alcohols.
  • 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.
  • 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 is a primary plasticizer?
  • A primary plasticizer enhances elongation, softness and flexibility of polymer. 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.
