Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. 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.
Plasticizer
It was commonly thought that plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing the "free volume"), [3] [4] or swelling them and thus significantly lowering the glass transition temperature for the plastic and making it softer.
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.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are general colorless liquids which are relatively nonvolatile. Most of the plasticizers used for carpets are esters of phthalic acids (phthalates) with a wide variety of long chain alcohols. Plasticizers are classified according to function or structure. The functional classifications are either primary or secondary.
Superplasticizer
Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete. [1]
- 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 are plasticizers used in film coating?
- 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.
- 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 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.
- 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 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:
