  • How do plasticizers change mechanical properties of a polymer?
  • Plasticizers are able to introduce new mechanical property changes when added into the matrix of the polymer as shown below in figure 1. The mechanism of action is termed plasticization. In addition, the mechanism of how the polymers are plasticized are described by theories which will be discussed in the later of this review.
  • Why are plasticizers marketed in high volumes?
  • 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.
  • Are plasticizers a problem in Germany?
  • We found an increasing number of substitutes in the German part of the three major European rivers Rhine, Danube and Elbe, as well as other waters in Germany. As a result, the total burden of plasticizers in the aquatic environment has hardly changed since 2005.
  • How are plasticizers characterized?
  • The produced plasticizers were characterized by GC, TGA, FTIR, and physicochemical properties. Their plasticizing performance was mainly evaluated by the analysis of physicochemical properties, mechanical properties, and plasticizer migration of the soft PVC samples and was compared with those of the commercial plasticizers DINP and DEHP.
  • 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.
  • Can plasticizers reduce the migration of polymers?
  • Efforts have been made to reduce the reduction of the migration of plasticizers in polymers through using more complex and higher molecular weight plasticizers which entangle in the polymer matrix to prevent migration. However, there is the downside of ineffective plasticization with this method.
