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 | 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...

DTDP plasticizer. Jayflex DTDP plasticizer is the highest-molecular-weight phthalate plasticizer, providing greater performance at high temperatures. It is the preferred plasticizer for automotive cable applications and THHN/NMB electrical wire insulation. Learn more.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Flexible samples with 0.32:1 plasticizer over PVC were selected to ensure a high migration rate of plasticizers. These results indicated that the new DOP-like plasticizer in PVC was...
Velsiflex Plasticizer | Benzoate Based, Non-Phthalate
As a vinyl plasticizer, Velsiflex has the solvating power that affords ample formulating latitude for optimized PVC formulations. Typical plastisol applications include calendering, flooring, or automotive plastisol sealants. Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature.
- 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.
- 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.
- 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].
- 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.
- What are flexible PVC (pPVC) formulations?
- Several flexible PVC (pPVC) formulations were compared in this study, including: pPVC@DEHP, using the monomeric plasticizer di (2-ethylhexyl) phthalate (DEHP); pPVC@PBA, using the polymeric plasticizer poly (butylene adipate) (PBA); and crosslinked pPVC (cPVC@DEHP), where isophorone diamine (IPDA) served as the crosslinker.
- Is PVC a good plasticizer?
- Thermal stability studies showed that PVC blends with HPGs were more stable (exhibiting higher onset temperature values on TGA curves) than samples with DEHP. A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance.
