  • How to reduce leaching and migration of plasticizers from polymer surface?
  • Leaching and migration of plasticizers from polymer surface can be reduced by coating the polymer surface with some non-migrating material. But these coatings are usually thick and may often cause a reduction in flexibility of the polymeric materials.
  • How do plasticizers affect a polymer?
  • Plasticizers are expected to reduce the modulus, tensile strength, hardness, density, melt viscosity, glass transition temperature, electrostatic chargeability and volume resistivity of a polymer, while at the same time increasing its flexibility, elongation at break, toughness, dielectric constant and power factor .
  • Are plasticizers compatible with polymers?
  • As has already been discussed, the plasticizing efficiency and thermodynamic compatibility of plasticizers with polymers depend on a number of properties such as chemical structure, MW, functional groups, alkyl chain length and diffusion and solubility parameters of the plasticizers.
  • Can polymeric Plasticizers improve leaching resistance?
  • Reprinted from Ref. , © (2003), with permission from John Wiley and Sons, Inc. While polymeric plasticizers may cause a reduced flexibility in plastic materials, they can also be used in combination with traditional plasticizers to improve leaching resistance of the latter.
  • What are plasticizers used for?
  • This publication is licensed for personal use by The American Chemical Society. Plasticizers are synthetic chemicals that are commonly used in polyvinyl chloride (PVC) based products, food packaging, children’s toys, medical devices, and adhesives. There are about 30 000 chemicals can potentially be utilized as plasticizers.
  • Why are flexible plasticizers limited in their end use?
  • Most flexible plastics are limited in their end use because plasticizers are generally low-to-medium MW chemicals with measurable vapor pressure below their boiling points.
