  • 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.
  • 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 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.
  • 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.
  • Is polyvinyl chloride a base plasticizer?
  • If the polymer is soluble in the plasticizer, it is called a base plasticizer. Polyvinyl chloride (PVC) is the second pure polymer after polyethylene in the European market. Although polymer as a pure resin has poor applications and requires the use of additives to produce products of acceptable quality.
  • How do you plasticize a polymer?
  • A polymer can be internally plasticized by chemically modifying the polymer or monomer. This increases flexibility. It involves copolymerization of the monomers of the desired polymer (having high Tg) and that of the plasticizer (having low Tg) so that the plasticizer is an integral part of the polymer chain.
