Plasticizer - an overview | ScienceDirect Topics
To make PVC flexible at least 15 phr plasticizer is required. Less than this amount induces antiplasticization, and actually increases stiffness. Plasticizers can be used alone or in combination to get the desired properties such as tensile and tear strength or low temperature flexibility.
Immobile plasticizer in flexible PVC | Nature
When the surfaces of flexible PVC sheets were similarly modified, we found that plasticizer migration could be prevented completely, as it was in PVC tubes. How-ever, modification led to a...
Eastman Plasticizers for PVC
Benzoflex - 181 Plasticizer Benzoflex181 is a water white alkyl benzoate ester with low odor, low viscosity and excellent compatibility with PVC. Benzoflex181’s principal use is as a low viscosity plasticizer for plastisol applications. Benzoflex 181 may also be used in other applications requiring a low viscosity, high solvating plasticizer.
Immobile plasticizer in flexible PVC - ResearchGate
Poly (vinyl chloride)(PVC), as the second general plastic just following the product of polyethylene (PE), has been widely applied in building, electrical parts, automobile, package and other

VESTINOL 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window. ELATUR DPT (DiPentylTerephthalate) plasticizer has very low Volatile Organic Compound (VOC) residue build-up, has a low viscosity, and is fast fusing upon gelation.
- How stable is unplasticized PVC?
- Unplasticized PVC was stable up to 212 °C, whereas the addition of plasticizers deteriorated its thermal stability to some extent for every plasticizer studied. Table 3 offers a comparison of the PVC samples where the temperatures at which samples lost 10% of their initial weights have been reported.
- Are plasticizers able to produce Flexible PVC?
- All the ILs tested were able to produce flexible PVC. Upon 20 wt% plasticization, some of the ILs lowered the glass transition temperature ( Tg) of PVC more than that done by several traditional plasticizers. They showed good thermodynamic compatibility as well.
- Are room temperature ionic liquids a plasticizer for poly (vinyl chloride)?
- Room temperature ionic liquids (ILs), based on ammonium, imidazolium and phosphonium cations, were studied as novel plasticizers for poly (vinyl chloride), PVC. All the ILs tested were able to produce flexible PVC.
- 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.
- Does BZ- -Cd inhibit plasticizer migration in flexible PVC?
- The presence of Bz- β -CD in the PVC matrix played a key role in inhibiting plasticizer migration which may explain the improved stability of the flexible PVC. This research was supported by the Eco-Innovation Project through the Korea Ministry of Environment. Supplementary data 1.
- Can plasticizer migration be prevented?
- When the surfaces of flexible PVC sheets were similarly modified, we found that plasticizer migration could be prevented completely, as it was in PVC tubes. How-ever, modification led to a decrease in the stress (about 8 per cent) and strain (about 28 per cent) at the breaking point for PVC sheets.
