  • What are plasticizer characteristics?
  • Plasticizer characteristics determine not only the compatibility but also the amount which can be added to the polymer while ensuring the thermodynamic stability of the mixture. Thermodynamic stability means the absence of plasticizer exudation at temperature changes, mechanical stresses, and pressure.
  • Which plasticizer has the best plasticizing efficiency?
  • It's worth noting that PSCH has the best plasticizing efficiency attributed to the C–Cl bond on the side. According to the similar compatibility principle, except for hydrogen bonding, the existence of C–Cl bond in PSCH increases the compatibility of plasticizer and PVC.
  • Can plasticizers reduce material degradation over time?
  • The design of new plasticizers compatible with the polymer at high concentrations, tailored to be effective in lowering the glass transition temperature, and with a low tendency to migration could considerably reduce material degradation over time.
  • How do Plasticizers improve plasticity?
  • The molecules of plasticizers can insert themselves between polymer chains, increasing the distance between the chains and weakening intermolecular forces. This makes the polymer more flexible and easily bendable. It enhances the plasticity of plastics, making them easier to bend and deform.
  • What is a plasticizer used for?
  • More often plasticizers are used with other polymer systems for processing improvements rather than for producing flexible products. Plasticizers can be used with acrylic polymers to produce flexible coatings, caulks, and sealants, sometimes serving a role as a coalescing agent instead of a plasticizer.
  • Do plasticizers increase polymers' flexibility at room temperature?
  • Disentanglement of CA chains is favored at higher plasticizer content under extensional flow, yielding lower melt strength and higher melt extensibility . These observations confirm that plasticizers increase polymers' flexibility at room temperature and can be used as processing aids.
