Methods for determination of plasticizer migration
Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather. In this context, the establishment of standard assays that measure the migration rate of plasticizers under varying scenarios plays a pivotal role in comparing durability of those

Plasticizer - an overview | ScienceDirect Topics
Plasticizer. 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 glass lenses, drinking bottles, food

- How do plasticizers affect a polymer?
- For example, commonly they are integrated polymer chains, plasticizers reduce intermolecular forces, thereby increasing the material’s plasticity and decreasing its viscosity. This modification transforms rigid and brittle polymers into more pliable forms, broadening their application spectrum.
- Why do Plasticizers make polymers soft and pliable at lower temperatures?
- By lowering Tg, plasticizers make polymers soft and pliable at lower temperatures. Decreasing Crystallinity: Some polymers, like PVC, have regions of crystallinity that make them naturally rigid. Plasticizers reduce crystallinity, further enhancing flexibility and elasticity.
- What is a citrate plasticizer?
- Citrates (TOC, ATBC, and ATOC, etc): Derived from citric acid, citrate plasticizers are often used in applications requiring non-toxic and biodegradable additives, such as in food packaging and medical products.
- Why are plasticizers important?
- For electrical applications, they provide flexibility and durability in cable insulation, ensuring safety and performance. In healthcare, plasticizers are vital for flexible medical devices like IV bags, blood bags, and catheters, ensuring functionality and patient comfort.
- What are the different types of plasticizers?
- The primary types include: Phthalates: These are the most commonly used plasticizers, primarily employed to impart flexibility to polyvinyl chloride (PVC) products. Phthalates are esters of phthalic acid and are divided into high and low molecular weight categories.
- How do plasticizers work?
- Maintaining Long-Term Performance: Plasticizers ensure that the polymer remains flexible throughout its lifespan. In short, plasticizers work by embedding themselves between polymer chains, reducing intermolecular forces, lowering the glass transition temperature, and decreasing crystallinity.
