  • What are plasticizers used for?
  • Introduction Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
  • What are low molecular weight plasticizers?
  • Low molecular weight plasticizers are added before or during the processing to reduce the melt processing temperature. However, these low molecular weight plasticizers may have some drawbacks, such as volatility, high water solubility, and insufficient compatibility with CA.
  • What is the best plasticizer?
  • The best migration test result obtained was 70% lower than that for DEHP or DINP. The ester mixture that was found to be the most favorable plasticizer was characterized by good thermal and thermo-oxidative stability (5% weight loss temperature: 227.8 °C in air and 261.1 °C in nitrogen).
  • Which plasticizer is most stable after 10 d?
  • After 10 d, the migration trend of all samples had been stabled, it showed that the traditional plasticizer like DOP, DOTP and DOA had basically move out from the PVC matrix in non-polar environment due to their own single structure, while the PVC plasticized with A-ODL showed the best stability in all the environment.
  • How effective is a plasticizer?
  • The effectiveness of a plasticizer depends on the molecular weight of a plasticizer and the ratio of individual components in a molecule, i.e., polar groups, non-polar polarizable groups, and non-polar non-polarizable groups [ 68 ].
  • 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.
