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
Immobile plasticizer in flexible PVC | Nature
Plasticized poly (vinyl chloride) (PVC) is one of the most widely used polymeric materials in medical and related applications, and usually contains up to 40 per cent di- (2-ethylhexyl)phthalate...
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
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.
New phthalate-free plasticizer gives flexible PVC an
Plasticizers make up a significant part of PVC (up to 40% in some applications), so the availability of Pevalen Pro can help producers to lower their carbon footprint. Using the new Pevalen Pro will increase that pro-environmental advantage, and will be initially available with up to 40% renewable content, with the long-term potential of
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- 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 plasticizer nature influence the uptake kinetics in coextruded PVC pipes?
- The uptake kinetics is strongly influenced by plasticizer nature and PVC state. Technologically relevant for plasticizer migration studies in coextruded PVC pipes. This study introduces and validates an effective approach for monitoring the plasticizer amount and its concentration profile in polyvinyl chloride (PVC) formulations.
- 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.
- Why is plasticizer important?
- Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC. Therefore, plasticizers are the most important commercial application of PVC. However, plasticizers can leach out of flexible PVC, changing the performance of PVC with age and contaminating the environment.
- 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.
