Plasticizer
Plasticizer. Stray plasticizers migrating from a soft vinyl eraser have partially dissolved a plastic pen cap over the course of time. A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its
Plasticizers – Chemical Economics Handbook (CEH)
Published May 2021. Flexible polyvinyl chloride (PVC) accounts for 80¨C90% of global plasticizer consumption. Flexible PVC (and thus plasticizers) is found in the following applications: construction (flooring, wall coverings), electrical (wire and cable jacketing), consumer goods (toys, footwear, etc.), packaging, transportation (inside and outside of vehicles), furnishings, and medical uses
Plasticiser loss from plastic or rubber products through diffusion
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…
Natural-based plasticizers and biopolymer films: A review
Plasticizers are, in general, high boiling point liquids with average molecular weights of between 300 and 600, and linear or cyclic carbon chains (14¨C40 carbons) [12], [13]. The low molecular size of a plasticizer allows it to occupy intermolecular spaces between polymer chains, reducing secondary forces among them.

A Strategy for 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

Plasticizers: Types, Uses, Classification, Selection & Regulation
What are plasticizers? Plasticizers are relatively non-volatile organic substances (mainly liquids). When incorporated into a plastic or elastomer, they help improve the polymer’s: Flexibility and makes a product softer Extensibility – They do not break easily at cold temperatures Processability becomes possible and easier
Introduction
1.2.2 Major Functions of Plasticizers. The plasticizer is a type of substance that increases plasticity while not affecting the properties of plastics. Here are the major functions of plasticizers: weakening van der Waals interactions between the polymer chains; increasing the mobility of polymer chains (i.e., plasticity); enhancing the extensibility, flexibility, and flexurity; decreasing the
