Citroflex Plasticizers for Flexible PVC - ChemPoint
Phthalate plasticizers, including DEHP, have been the primary plasticizers used in polyvinyl chloride (PVC) based products for many years. Citroflex citric acid esters are excellent alternatives to phthalate-based plasticizers as they provide a better balance of physical properties and low volatility when used in PVC systems.

Typical low temperature plasticizers include Adimoll adipates, Uniplex sebacates and Disflamoll TOF. Compatibility. Compatibility of a plasticizer can be determined fairly quickly and simply by way of the dissolution temperature. A PVC / plasticizer suspension (1:19) is heated.
Plasticizers for PVC | POLYNT
About Plasticizers for PVC. The plasticizers are organic substances with various characteristics, whose main function is to intercalate the rigid polymer structures of material such as PVC for an easy movement and flexibility, making them more precisely "plastics." The presence of plasticizers in the PVC structure will influence different
New Pevalen Pro plasticizer gives flexible PVC an
Perstorp is launching a new renewable polyol ester (non-phthalate) plasticizer Pevalen Pro. It will make flexible PVC an even more attractive choice of plastic, based on a significantly lower carbon footprint versus competing materials and technologies. Pevalen Pro not only gives PVC an environmental boost as a renewable true non-phthalate plasticizer but also provides superior performance
- Where can plasticizers be used?
- The plasticizer can migrate from PVC-based devices and storage bags into physiological fluids, however, and has been detected in storage media such as blood, plasma, serum, drug solutions and fatty foods 2, 3, 4, as well as in the bodies of patients undergoing haemodialysis and transfusion 5.
- Which plasticizers are used in flexible PVC?
- In flexible PVC formulations, esters derived from phthalic acid are the most common monomeric plasticizers, although other compounds based on various organic acids (phosphates, trimellitates, citrates, sebacates, and adipates) can also be used [6, 7].
- Does flexible PVC reduce plasticizer leaching?
- In this study, the plasticizer migration from flexible PVC in contact with rigid PVC sheets was investigated. Various formulations of flexible PVC were compared, highlighting reduced plasticizer leaching when pPVC was chemically crosslinked or when the monomeric plasticizer, DEHP, was replaced with the polymeric plasticizer, PBA.
- Are flexidone plastisols more efficient than standard plasticizers?
- Gelling curves of PVC plastisols (50 phr plasticizer) with various mixtures of Vestinol 9 and Flexidone100, 300, DBP and BBP. 5. Conclusion It could be shown, that Flexidone’s are very efficient PVC plasticizers. They are up to 50% more efficient than standard plasticizer.
- Do flexible PVC films migrate to RPVC films?
- As described in the experimental section, migration tests were conducted following the UNI EN ISO 177 standard. Flexible PVC formulations were kept in contact with rPVC films, and the plasticizer migration was evaluated by monitoring the weight increase of the rPVC sheet over time.
- 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.
