  • Are plasticizers considered softeners?
  • Plasticizers are often referred to as softeners. In the 1920’s, researchers discovered that many esters of the polycarboxylic acid group, such as phthalic acid and phosphoric acid, were able to react with high polymers to form a homogeneous physical compound.
  • 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 used for?
  • Plasticizers are primarily used in the production of flexible PVC, accounting for around 90% of their applications. They have minor uses in rubber, adhesives, sealants, paints, lacquers, and lubricants. To obtain soft PVC, plasticizers must have the following essential performance properties: Plasticizers are used to make PVC more flexible.
  • How do plasticizers affect tensile strength?
  • Plasticizers increase flexibility by lowering the glass transition temperature of polymers, decrease tensile strength but increase elongation and change the thermal properties so that the polymer is more easily worked by heat and perform better at low temperatures . What are the Different Types of Plasticizers?
  • What is plasticization in chemistry?
  • The term plasticization refers to the softening and increase in flexibility of a polymer. This change is due to the addition of specific additives, especially plasticizers. A plasticizer is a non-volatile substance incorporated in a plastic or elastomer. It changes the thermal and mechanical properties of the material.
  • How does a plasticizer interact with a polymer?
  • External plasticizers have a low vapor pressure. They interact with the polymer at high temperatures without a chemical reaction. The interaction happens through their solvent or swelling ability. It's essential to differentiate between solvent plasticizers and nonsolvent plasticizers.
