Plasticiser loss from plastic or rubber products through
Polymers experience degradation during storage and service. One of the main degradation mechanisms of plasticised-polymer products is the loss of plasticiser, which leads to poorer mechanical
What Plasticizers Do & How They Affect Properties | Osborne
Approximately 90% of all plasticizers are used in polyvinyl chloride, or PVC. By volume, after Polyethylene (PE) and Polypropylene (PP), PVC is the third largest polymer used in products. PVC is one of the most durable materials in the world because of plasticizers added to it, lasting up to 50 years without damage.
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.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt. Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry.

Phthalates are in hundreds of products, such as vinyl flooring, lubricating oils, and personal-care products (soaps, shampoos, hair sprays). Some phthalates are in polyvinyl chloride plastics, which are used to make products such as plastic packaging, garden hoses, and medical tubing. How People Are Exposed to Phthalates
- 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.
- How do plasticizers affect the microstructure of amorphous and semicrystalline polymers?
- Plasticizers affect the microstructure of amorphous and semicrystalline polymers to achieve the desired properties. All polymer materials have amorphous regions that are disorganized and inefficiently packed, allowing some degree of flexibility.
- Why are plasticizers bad for the environment?
- This is often a negative outcome of plasticizers and can contaminate foods and alter nearby materials in undesirable ways which could lead to failure. Leaching is the process by which plasticizers are released by a material into a liquid, typically water, which is the most concerning for both health and environmental reasons.
- Why are plasticizers important?
- Plasticizers are invaluable tools for engineers and scientists to manipulate the properties of polymeric systems for both the desired end products and the ease of processing those goods.
- 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:
- How does plasticizer affect the mobility of a polymer chain?
- The mobility of a polymer chain is more complex in the presence of plasticizer than what the Flory–Fox equation predicts for a simple polymer chain. The molecules of plasticizer take control over mobility of the chain - a polymer chain does not show an increase of the free volume around polymer ends.
