  • 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 is the solvating strength of plasticizer?
  • The solvating strength of plasticizer depends on its chemical structure as it relates to its physical properties. Application of Hansen solubility parameters (δd = dispersion interactive forces, δ p = dipole interactive forces, and δ h = hydrogen bonding forces) is the most successful method of predicting interaction between plasticizers and PVC.
  • 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.
  • How are plasticizers classified?
  • Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
  • Which plasticizer has the lowest volatility?
  • The Red Curve Shows Volatility, the Blue Curve Compatibility, and the Green Curve Shows the Solubility Temperature. Plasticizers like DINP and DIDP would typically offer the lowest volatility among the general-purpose plasticizers and good retained mechanical properties after aging.
  • What are the requirements for plasticizers?
  • Plasticizers have to meet several requirements mentioned below. First and most important, they need to be compatible and permanent to stay durably in the final article. Plasticizers also need to withstand heat and shear during processing and sustain severe aging conditions.
