Study of the migration of PVC plasticizers - ScienceDirect
Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer thermobalance, by heating the sample from 25 to 600 °C at 10 °C/min under a 20 ml (STP)/min flow of nitrogen. 3. Results and discussion Thermogravimetric study of different polystyrene samples reveals marked differences in the degradation process.
Phthalate Plasticizers Covalently Bound to PVC
The internal plasticization of PVC by displacement of chlorine with phthalate-based thiol additives, that is, the covalent attachment of the plasticizer to the PVC chain, is described for the first time. Using this methodology, a good plasticization efficiency is achieved although flexibility is reduced compared with that of commercial PVCphthalate systems. However, the migration is

Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications.
Migration of plasticizers phthalates, bisphenol A and
Migration of plasticizers phthalates, bisphenol A and alkylphenols from plastic containers and evaluation of risk This study investigates the potential migration of plasticisers, plastic components and additives from several plastic water bottles.
- Do phthalate plasticizers have migration resistance?
- There are a lot of studies describing novel plasticizers that exhibit excellent migration resistance at the expense of the deterioration of mechanical properties. Since phthalate plasticizers have become a subject of legal restrictions in many countries, developing a robust plasticizer emerges as an urgent need.
- How can phthalates be removed from the environment?
- Phthalates can be degraded by microorganisms and in this way can be eliminated from the environment, and the most effective disposal approach is through hydrolytic decomposition to phthalic acid and alcohols . The migration studies of plasticizers are usually divided into four types:
- Do plasticizers migrate from PVC to distilled water?
- Nevertheless, plasticizer migration from PVC blends with only one plasticizer, including extraction in distilled water, exudation and volatility, was investigated, showing the highest volatility of PVC/CA (about three times higher than for PVC/DOTP) and comparable extraction in distilled water.
- Do plasticizers migrate from PVC to DOP?
- As expected, the migration of plasticizers was equal to zero. Mechanical properties of the material with modified PVC were compared to a material plasticized by DOP. The commonly used plasticizer provided significantly lower tensile strength and higher elongation at break than the modified one.
- Which plasticizer has the highest molecular weight?
- Both methods indicated DEHP as the plasticizer with the highest migration, and palm oil-based as the plasticizer with the highest molecular weight as the one with the lowest migration.
- What phthalates are found in plastic water bottles?
- plastic water bottles. Compounds studied were phthalates (dimethyl phthalate, di- n -butyl phthalate, benzylbutyl and (3) standard method UNE-EN 13130-1. In addition, bottled waters contained in different plastic materials were analysed to determine the potential migration of target compounds in real conditions. In all cases, samples mode.
