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.
Selecting Plasticizers for Adhesives and Sealants
However, plasticizers can also supply additional benefits that are important to both the formulator and end-user. A large number of different resins and plasticizers are used with adhesives and sealants. There are over 38 general chemical families of plasticizers and multiple types within each family. This makes the process of selecting a
Plasticizers in Paint & Coatings: Uses, Types and Selection
Some alternative plasticizers as proposed for coatings are ATBC, SAIB, DOA and EPO. Although main properties of phthalate-based plasticizers can be met, the other alternative products tend to be more sensitive to migration as compared to DOP or DIOP. Acetyl Tri-Butyl Citrate (ATBC)
Plasticisers - Information Center
The most common plasticisers include esters such as adipates, azelates, citrates, benzoates, ortho-phthalates, terephthalates, sebacates, and trimellitates.
- Which materials can be plasticized with citrates?
- Some properties of materials plasticized with citrates can match those plasticized with DOP but the cost of their production is substantially higher. Tri Butyl Citrate is a high boiling substance, is used as a solvent and plasticizer for polymers especially for PVC and its copolymers which are subsequently applied to food wrapping film.
- What is a citrate plasticizer?
- Citrate plasticizers are made of citrates which are esters of citric acid. They can be found in oily liquid form and they are practically colourless and odourless. They are used in paints, coatings and inks but also in food packaging products, cling wrap, toys and medical applications.
- Why are citrate plasticizers not used in film applications?
- However, citrate plasticizers are highly volatile and a significant amount is lost due to this property. Citrates lack permanency. Hence, they are not employed in resilient applications like cables, flooring, or roofing. They induce more fogging in film applications.
- Can citrates replace phthalates?
- Citrates are also used in toys produced by the plastisol process. Citric acid based plasticizers are one of the major contenders to replace phthalates (especially targeted to replace DOP). Some properties of materials plasticized with citrates can match those plasticized with DOP but the cost of their production is substantially higher.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
