Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
Long- and short-term stability of plasticized poly(lactic acid
In this work, PLA was plasticized with poly (ethylene glycol) (PEG) having different molecular weights such as 400, 8000 and 35,000 g/mol at various concentrations ranging from 5 to 20%. In addition, a new plasticizer, PEG-functionalized polyhedral oligomeric silsesquioxane (PEG-POSS), was used for comparison.
Plasticizers – Benefits, Trends, Health, and Environmental Issues
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.
Selection of Plasticizers for Coating Formulations
Good stability to heat and ultraviolet light Broad range of compatibility, and Excellent resistance to hydrolysis Di-iso-octyl phthalate (DIOP) DIOP is like DOP, an all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane.

and concentrations of plasticizers could improve the poor mechanical properties and brittleness of the composite lm for a longer storage time. However, only PEG 400 at 5% and 10% w/w acted as a good plas-ticizer capable of improving the stability of the composite lm under the longer periods of storage. There-
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
- Do Plasticizers improve the mechanical and thermal properties of PVC?
- To improve the mechanical and thermal properties of PVC, plasticizers are introduced into the polymer (Unar et al., 2010). Furthermore, the plasticizers also provide sufficient elasticity, flexibility, and malleability to the final products.
- Which plasticizer has a strong solvation power?
- The solubility parameter is increased as polarity and/or aromaticity is increased. Examples of plasticizers with strong solvation power are benzoates esters, sulfonates, tricresyl phos-phate (TCP), dihexyl phthalates (DHP), butyl octyl phthalates (BOP), and butyl benzyl phthalates (BBP) (Wikes et al., 2005).
- Are bio based plasticizers safe?
- The petroleum based plasticizers (phthalates) have high leachability properties since they do not strongly bond to the polymer. This has posed high risk on human health and to the environ-ment. For these reasons, bio based plasticizers are introduced due to less leachability, volatility, toxicity, and good compatibility with PVC.
- Are petroleum based plasticizers toxic?
- Petroleum based plasticizers are known to be toxic in nature and can be detrimental to human’s health. For this reason, bioplasticizers have been introduced to the plastic industry due to its low toxicity, leachability, enhanced thermal and mechanical properties and its high compatibility with PVC.
