Plasticizer
For example, plasticizers are commonly added to polyvinyl chloride (PVC), which otherwise is hard and brittle, to make it soft and pliable; which makes it suitable for products such as shower curtains, vinyl flooring, clothing, bags, flexible plastic tubing, and electric wire insulation/coating.
Plasticizer Definition & Meaning - Merriam-Webster

Natural-based plasticizers and biopolymer films: A review
The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
What are the purpose and usage of Plasticizers?
Plasticizers are the admixtures used to mix in cement to improve their qualities and make them suitable for construction. It’s effects on concrete: 1)Reduce the water/cement ratio without any effect on workability. 2)It increase setting time. It allows transit mixers to transport concrete too long distances.
Plasticizer - an overview | ScienceDirect Topics
Plasticisers are low-molecular-weight polymers that increase the spacing between chains of crystalline polymer to make them more flexible and, thereby, tougher.

- 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:
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- Why is plasticization important?
- Plasticization is the process of making the final plastic product more flexible. By incorporating the right type and amount of plasticizer you can tweak your formulation. Hence, selecting the right plasticizer for a specific application is very critical to make the product softer. Plasticization can occur both internally and externally.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
