  • Do plasticizers deteriorate the thermal stability of plasticized PVC?
  • When plasticized samples were subjected to the same temperature ramp, dramatic differences were observed compared to the above results for the plasticizers alone. Unplasticized PVC was stable up to 212 °C, whereas the addition of plasticizers deteriorated its thermal stability to some extent for every plasticizer studied.
  • Which plasticizer withstands leaching?
  • From leaching point of view, the best plasticizers are those that do not leave the polymer. Thus, plasticizers at the left end, e.g., Citroflex A6 and Citroflex B6 are good plasticizers, and so is [thtdPh + ] [Tf 2 N − ]. A second consideration for good plasticization that withstands leaching is whether the modulus changes much after the leaching.
  • How stable is a plasticizer at 200 °C?
  • From this test, it is possible to appreciate that the plasticizer is stable up to 200 °C without any appreciable signal due to evaporation transition, in accordance with the low volatility described previously. Interestingly, we have noticed that the plasticizer presents its own Tg of approx. −49 °C evaluated with a scanning rate of 20 °C·min –1.
  • Are DL isoborneol esters a good plasticizer for polyvinyl chloride?
  • Hong‐ying Chu, Chuan Gao, Shuai Huang, Xin‐Ding Yao. DL ‐Isoborneol esters as nontoxic main plasticizers for polyvinyl chloride with improved processability, thermal stability, and mechanical performance.
  • What are biodegradable plasticizers?
  • Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
  • What is the most common plasticizer in the world?
  • (8) Despite growing awareness of the harm that phthalates present, DEHP continues to be the most frequently used plasticizer in the world and can be found in commercial PVC in concentrations up to 30–40 wt %.
