Plasticizer
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 handling in manufacture.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
Plasticiser loss from plastic or rubber products through
Plasticisers are commonly added to polymers to lower their glass transition temperature and increase their processability, mechanical flexibility, ductility and toughness. 1, 2, 3, 4, 5 They...

Plasticizers In Polymers Definition Plasticizers are low molecular weight organic compounds that are non-volatile in nature. Most of the plasticizers are taken in liquid form. Plasticizers improve the flexibility, processes the ability and utility of the polymers.
Polymer Chemistry: Factors Influencing Tg - Engineering
Plasticizers; Contributors and Attributions; The value of T g depends on the mobility of the polymer chain - the more immobile the chain, the higher the value of T g. In particular, anything that restricts rotational motion within the chain should raise T g. A polymer chain that can move easily will change from a glass to a rubber at a low
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
- Why do polymers need plasticizers?
- The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials. The main problem of these additives is that, over time, they migrate from the polymeric matrix and exude to the surface of polymeric matrix.
- How do you plasticize a polymer?
- A polymer can be internally plasticized by chemically modifying the polymer or monomer. This increases flexibility. It involves copolymerization of the monomers of the desired polymer (having high Tg) and that of the plasticizer (having low Tg) so that the plasticizer is an integral part of the polymer chain.
- Are plasticizers a principal component of a polymeric material?
- Although the principal component of a polymeric material is the polymer, even if plasticizers are used in proportions up to 55 %, they are considered a principal part of a formulation rather than additives. Plasticizers are intermediate chemical products whose properties determine greatly the performance of the products which they are added.
- What is a reactive plasticizer?
- Learn more. This review is about the reactive plasticizer. Plasticizers are small molecules with low molecular weight. These compounds typically have an esteric structure. The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
