  • What makes a polymeric plasticizer a more migration-resistant plasticizer?
  • A more migration-resistant polymeric plasticizer that also better preserved its material properties during aging was obtained by combining a low degree of branching, hydrolysis-protecting end-groups, and higher molecular weight.

  • Why do plasticizers migrate?
  • The primary purpose of a plasticizer is to enhance a product's flexibility. When plasticizers migrate out of the product, flexibility is compromised, leading to embrittlement. Plasticizer migration can trigger the migration of other additives (e.g., UV stabilizers, antioxidants, etc.). This results in the deterioration of the overall performance.
  • Are plasticizers colorless?
  • Plasticized plastics maintain their color, as most commercial-grade plasticizers are colorless ("water white"). Avoid using colored plasticizers to prevent undesirable coloration in flexible PVC compositions. Select 30+ plasticizers offering color stability in our database. Plasticizers prevent the development of microcracks in the polymer matrix.
  • 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.
  • What happens if you move plasticizers?
  • Fogging: Outgassing of plasticizers in automotive dashboards causes surrounding glass to fog up. Paint issues: Migrating plasticizers can harm the finish and create problems during repainting. Leaching: Pigment is carried away with migrating plasticizers. This causes it to 'leach' down the substrate.
  • Can macromolecular engineering improve the migration resistance of polymeric plasticizers?
  • This paper summarizes current literature on the migration of monomeric and polymeric PVC plasticizers from medical materials, food packaging, and toys. Especially highlighted is macromolecular engineering as a tool to increase the plasticizing efficiency and migration resistance for polymeric plasticizers.
