  • Does polycarbonate crack when in contact with PVC plasticized?
  • no evidence to stress-cracking when in contact with PVC plasticized by the P S-160,000 polyester. The compound containing PeS-5,000 induces minimal cracking to polycarbonate.The visible signs of stress- ack development in polycarbonate are one way of evaluating performance in a specific environment. Polycarbonate has a high degree of elo
  • Can polymer plasticizer improve thermal stability of PVC materials?
  • Both the high and lower branching of polyester plasticizer can improve thermal stability of PVC materials compared to DEHP. Hyperbranched poly (ε-caprolactone) (PCL) with different lengths of linear segments and different numbers of branches, as the polymer plasticizers, show no migration in volatility, extractability, and exudation tests .
  • Why do flexible PVC products need plasticizers?
  • The properties of flexible PVC products significantly change with addition of plasticizers, such as reduction of the glass transition temperature (Tg) and tensile strength, while elongation will increase, which make PVC change from hard and brittle to flexible, thus greatly expand its application [, , ].
  • Can polymer plasticizer extend the life of PVC-membrane ion-selective electrodes?
  • Polymeric plasticizer, such as poly (butylene sebacate), can extend the life time of PVC-membrane ion-selective electrodes and keep their property long stable [84, 85]. PBA with molecular weights ranging from 2000 to 10000 g/mol and PVC is not completely compatible and forms a semimiscible two-phase system.
  • Which triester is a stress-inducing plasticizer?
  • exyl azelate (DOZ) and diisodecyl glutarate (DIDG) cause severe stress-cracking to polycarbonate. A triester, tri-2-ethylhexyl trimellitate (TOTM), was also evaluated and found to provide slig t improvement over diesters, but still considered to be an aggressive stress-inducing plasticizer.
  • Does polyester plasticizer reduce migration resistance?
  • High degree of branching of polyester plasticizer more effective to reduce migration resistance than low degree of branching of polyester plasticizer. Both the high and lower branching of polyester plasticizer can improve thermal stability of PVC materials compared to DEHP.
