Plasticizer
Plasticizers are also often added to concrete formulations to make them more workable and fluid for pouring, thus allowing the water contents to be reduced. Similarly, they are often added to clays, stucco, solid rocket fuel, and other pastes prior to molding and forming. For these applications, plasticizers largely overlap with dispersants .
Plasticizers – Benefits, Trends, Health, and Environmental
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.
Plasticizer - an overview | ScienceDirect Topics
Plasticisers are compounds which increase the plasticity of a material and are often involved in the production of plastic products/packaging, epoxy resins (coating cans for food and beverage), water pipe lining, thermal printing paper, implanted medical devices and in the production of CDs and DVDs, mobile phones, plastic food containers, eye
What Plasticizers Do & How They Affect Properties | Osborne
Plasticizers act like a lubricant among polymer chains to reduce rigidity. Without them, synthetic polymer materials would be too brittle and rigid for any practical purpose. For example, plasticizers give rubber its extensibility. Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC.

What is the function of plasticizers? increase flexibility, workability, and distensibility of plastic Addition of plastic causes REDUCTION of cohesive intermolecular forces 80% of consumption of plasticizers is DEHP, DINP, DIDP What is the chemical structure of phthalates? 1,2-benzene-dicarboxylic acid
- 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.
- 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 is primary plasticizer?
- If the plasticizer induces softness and elongation when added to the polymer, it is called primary plasticizer.
- What are the benefits of plasticizers?
- One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years. Without plasticizers, PVC can only be rigid, such as the PVC used in wastewater pipes.
- 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.
- 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.
