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.
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.
Plasticizers Prices: Latest Price, Pricing, News, Market Analysis
North America. Plasticizers prices rose sharply in Q1 2025 as a result of the sharp rise in crude oil prices and improved downstream demand. The price of dioctyl phthalate averaged 1875 USD/MT towards the end of first sector. The increase in upstream value prices and the strengthening domestic market demand were the main factors influencing
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 the features of a plasticizer?
- Perfect for a variety of flexible and semi-rigid applications, features of plasticizers include: Excellent low temperature and food contact properties General use in the vinyl industry with maximum residual alcohol of 350 ppm Ask about our DOTP plasticizer grades manufactured with recycled PET bottles
- How does a plasticizer interact with a polymer?
- External plasticizers have a low vapor pressure. They interact with the polymer at high temperatures without a chemical reaction. The interaction happens through their solvent or swelling ability. It's essential to differentiate between solvent plasticizers and nonsolvent plasticizers.
- Why are external plasticizers used in polymerization?
- 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. The interaction happens through their solvent or swelling ability.
- What is the Ultimate Guide to plasticizers in 2024?
- Welcome to the Ultimate Guide to Plasticizers in 2024. This comprehensive resource provides an in-depth exploration of plasticizers, crucial additives that enhance the flexibility and processability of polymers. The guide will outline their classifications, delve into their applications, and compare different types.
- Why do Plasticized PVC products lose plasticizer?
- Over time, plasticized PVC products may experience loss of plasticizer due to migration or volatilization, which can affect their durability and performance. Factors such as the type of plasticizer, its compatibility with PVC, and the environmental conditions can influence the rate of this loss.
- How does a low polarity plasticizer work?
- The improved low-temperature flexibility depresses the glass transition temperature (Tg) of the polymer. Low-polarity plasticizers without aromatic moieties provide more rotational freedom vs. their higher-polarity counterparts of similar molecular weights. Aliphatic diesters of adipic, azelaic, and sebacic acids prove highly effective.
