Migration resistant polymeric plasticizer for poly(vinyl chloride
Flexible films of poly (vinyl chloride) (PVC) and linear or branched poly (butylene adipate) (PBA), synthesized from 1,4-butanediol and adipic acid or dimethyl ester of adipic acid, were aged in an aqueous environment for 10 weeks to study how branching, molar mass, and end-group functionality affect the leaching of polyester plasticizer from
Migration resistant polymeric plasticizer for poly(vinyl chloride
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, as well as in the bodies of patients undergoing haemodialysis and transfusion. 38 PDF Miscibility in PVC-polyester blends
Migration resistant polymeric plasticizer for poly(vinyl chloride
The polymeric plasticizers, poly (butylene adipate)s (PBAs), were obtained using different ratios of adipic acid or dimethyl esters of adipic acid and 1,4butanediol. ... Recent Attempts in...
Plasticiser loss from plastic or rubber products through diffusion and
The migration of plasticiser from polymers to a gas phase is a two-step process that includes diffusion from the polymer bulk to the surface followed by evaporation from the surface to the...
- Do Plasticizers improve the migration resistance of plasticized PVC material?
- This indicates that a moderate increase in the relative molecular weight of the plasticizer can effectively improve the migration resistance of the plasticized PVC material, a finding consistent with the results from the resistance tests. There has been no clear evidence observed regarding the plasticization process of plasticizers in PVC.
- Why is migration resistance important for PVC products?
- The migration resistance of plasticizers is a pivotal performance criterion for PVC products in the food packaging industry, as it directly impacts food safety.
- What are the optimal conditions for a monomeric plasticizer?
- Therefore, the optimal conditions for a monomeric plasticizer with superior plasticizing performance and excellent migration resistance include: (i) straight-chain molecular structure, (ii) molecular weight between 400 and 1200, (iii) balanced distribution of polar groups throughout the molecular chain.
- Can bio-based plasticizer improve optical properties of poly(vinyl chloride)?
- Lu M, Jiang P, Zhang P et al (2023) A highly stable bio-based plasticizer constructed from renewable acids for plasticizing and enhancing the optical properties of poly (vinyl chloride). New J Chem 47:1784–1796
- Do cyclic Plasticizers improve volatility resistance of plasticized PVC material?
- When compared to E-EOD-50, E-ECD-50, which features a cyclic structure, exhibited marginally lower weight loss, suggesting that plasticizers with a cyclic structure can modestly enhance the volatility resistance of the plasticized PVC material.
- Do plasticizers' molecular structures influence the performance of PVC?
- Furthermore, the influence of the plasticizers' molecular structures, specifically the cyclic versus straight-chain configurations, as well as their molecular weights, on the performance of PVC was thoroughly assessed.
