What Plasticizers Do & How They Affect Properties | Osborne
Because plasticizers can make the material stronger than before, PVC is largely used in the construction, automotive and wire and cable sectors. Familiar applications for PVC are pipes, sidings, window profiles, and medical devices.
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. One of the main benefits of plasticizers is the durability they confer onto
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.
Plasticizer - an overview | ScienceDirect Topics
Plasticizer selection involves trying to meet a combination of end-use performance requirements, processing needs, cost, and in some cases, specific regulatory requirements. Products produced from flexible PVC are used in a wide range of applications and industry market segments.
Selecting Plasticizers for Adhesives and Sealants
How do Plasticizers Work? Plasticizers are organic liquids or solids that are incorporated by melt processing or diffusion into a compatible polymer to reduce interaction between molecules and improve molecular mobility.
- 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 do plasticizers reduce TG?
- The reduction of Tg is proportional to the temperature difference between the Tg of the polymer and plasticizer. Plasticization improves the flexibility and processability of polymers. Certain factors can counteract or restrict this enhancement. Certain polymers may have limited compatibility with specific plasticizers, hindering their integration.
- 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.
- What is plasticization in chemistry?
- The term plasticization refers to the softening and increase in flexibility of a polymer. This change is due to the addition of specific additives, especially plasticizers. A plasticizer is a non-volatile substance incorporated in a plastic or elastomer. It changes the thermal and mechanical properties of the material.
- How to make a plastic product more flexible by adding plasticizers?
- The process of making the final plastic product more flexible by adding plasticizers is called plasticization. By adding the right type and amount of plasticizer, you can tweak the polymer properties to get exactly what you need.
- How do plasticizers affect a polymer?
- Well-chosen plasticizers can also improve resistance to UV exposure and chemical attack. This contributes to the long-term stability of the polymer. In specific applications, plasticizers can influence the dielectric properties of polymers.
