Braslau's team has been working to develop "nonmigratory" plasticizers that attach to the PVC polymer via a chemical bond and can't leach out of the plastic. She explained that traditionally, phthalates are mixed with
The new chemicals are effective as plasticizers for polyvinyl chloride (PVC) but can't leach out of PVC products because they are chemically bonded to the polymer chain.

While non-toxic plasticizers offer many benefits, challenges remain: Cost: Many non-toxic alternatives are more expensive than traditional phthalates, which can be a barrier to adoption. Performance: Not all non-toxic
An alternative plasticizer that doesn’t leach out of PVC is under development at the University of California Santa Cruz. Phthalates are typically combined with ground PVC and melted and

Polyvinyl chloride (PVC) is polymerized from vinyl chloride monomers and is one of the commonly used thermoplastic. Strength and modulus of PVC are the most excellent
Phthalates are semi-volatile organic compounds used in PVC building products to provide flexibility and other performance characteristics (see The PVC Debate: A Fresh Look).

The Consumer Product Safety Improvement Act of 2008 prohibited certain phthalates from use in child care articles and childrens toys. Thus, manufacturers have
Growing concern over the health effects of phthalates has spurred a search for alternatives that can add flexibility to plastics without leaching out.
- 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.
- Is -caprolactone a nonmigrating plasticizer for phthalates in flexible PVC?
- Toxicological Sciences. 71 (2), 146–153 (2003). Choi, J. & Kwak, S. Y. Hyperbranched poly (ε-caprolactone) as a nonmigrating alternative plasticizer for phthalates in flexible PVC. Environmental science & technology. 41 (10), 3763–3768 (2007).
- How can plasticizer migration be inhibited?
- Therefore, migration of plasticizer can be inhibited by the three following ways: (1) using plasticizers with higher molecular weight and hyperbranched degree, (2) increasing the interaction between plasticizer and PVC matrix, (3) modifying or coating the surface of soft PVC by physical or chemical methods for restricting the plasticizer migration.
- Which plasticizer has a low plasticizing efficiency?
- Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
- Do polymeric plasticizers have a low plasticizing efficiency?
- Unfortunately, they did not try them to PVC. In general, their large molecule size hinders diffusion in PVC to suppress migration. However, the rate of diffusion of the plasticizer is one of the most important factors determining plasticizer efficiency 33, 34. Polymeric plasticizer generally has low plasticizing efficiency.
- Is Plasticized PVC good for long-term use?
- Internally plasticized PVC can maintain its performance over long-term use because there is no plasticizer migration. However, internal plasticization is less efficient and generally has an unsatisfactorily narrow use temperature range.
