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.
What Plasticizers Do & How They Affect Properties | Osborne
Plasticizers are non-volatile chemical solvents used throughout the plastics industry to increase such properties as flexibility, pliability, durability, longevity, biodegradability, and extensibility in polymers.
Plasticizers: Types, Uses, Classification, Selection & Regulation
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. But, selecting the right plasticizer for an application has always been a daunting task.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer.
10. EFFECT OF PLASTICIZERS ON PROPERTIES
Since a low molecular weight plasticizer behaves like a solvent when mixed with a polymer, it leads to decrease of the cohesion between the macromolecular chains, and, consequently, to the...
- 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 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.
- Why are external plasticizers important?
- External plasticizers are significant in commercial uses. They provide more optimal property combinations. Compared to adding plasticizers during polymerization, they give manufacturers more flexibility in formulation. External plasticizers have a low vapor pressure. They interact with the polymer at high temperatures without a chemical reaction.
- 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 do plasticizers change properties?
- 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. The expected property changes in a plasticized plastic or elastomer are as follows:
- What factors affect plasticizer efficiency?
- Internal mobility (flexibility): This parameter plays a crucial role in determining plasticizer efficiency. This is true for various polymers unless polymer crystallinity is involved. The reduction of Tg is proportional to the temperature difference between the Tg of the polymer and plasticizer.
