Plasticizer - an overview | ScienceDirect Topics
Plasticizers lead to some environmental risks because of their eventual toxicity and the propensity to migrate toward other neighboring materials that could induce discoloration, stress cracking, and fogging. In addition, one must be vigilant for regulations concerning contact with food and medical articles.
Synthesis and Properties of a Novel Environmental Epoxidized
The degradation mechanism and possible interaction between EGERAE and PVC molecules in the plasticized system were also investigated. A novel renewable plasticizer based on castor oil, epoxidized glycidyl ester of ricinoleic acetic ester (EGERAE), was synthesized and applied into Poly(vinyl chloride) (PVC) for the first time.
Plasticizer - an overview | ScienceDirect Topics
Plasticizer loss causes plasticized PVC to shrink and become stiff. This can occur quickly at room temperature with low-molecular-weight plasticizers. As the molecular weight of plasticizer is increased, permanence at room or elevated temperature improves.
Plasticizer
The effect of plasticizers on elastic modulus is dependent on both temperature and plasticizer concentration. Below a certain concentration, referred to as the crossover concentration, a plasticizer can increase the modulus of a material. The material's glass transition temperature will decrease, however, at all concentrations.
Thermal degradation and plasticizing mechanism of poly(vinyl
The effect of CGE on thermal degradation of PVC films and its plasticizing mechanism were firstly reported. The molecular structure of CGE was characterized with Fourier transform infrared
- Are emerging plasticizers a regrettable substitution?
- This review compiles available data on toxicity, exposure, environmental effects, and safe production of emerging plasticizers. It identifies gaps in scientific research and provides evidence that emerging plasticizers are potential cases of regrettable substitution.
- Are emerging/alternative plasticizers harmful?
- Various emerging/alternative plasticizers entered the market following the ban on several phthalate plasticizers because of their harmful effects. However, there are limited data (especially peer-reviewed) on emerging plasticizers’ toxicity and environmental impact.
- Are plasticisers escaping into the environment?
- There have been no recorded cases of plasticisers escaping into the environment from these kinds of plastic.
- What are plasticizers & how do they work?
- 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.
- Why are plasticizers marketed in high volumes?
- Epub 2020 Feb 20. Plasticizers are marketed in high volumes and Di (2-ethylhexyl) phthalate (DEHP) is frequently detected in the environment and human populations. Industry had largely relied on DEHP until regulation started to restrict its marketing in 1999 due to environmental and human health concerns.
- Do phthalates and plasticizers exist in German rivers?
- The aim of this study was to obtain spatial-temporal trends for DEHP and its substitutes in German rivers. We have investigated suspended particulate matter (SPM) samples from the German Environmental Specimen Bank (ESB) for the presence of 23 plasticizers, i.e. 17 phthalates and 6 non-phthalates.
