There are two main groups of plasticizers: primary—the main plasticizer in a PVC blend, added in large quantities and highly compatible with PVC; and secondary—having limited compatibility with PVC, easily migrating, especially
Plasticizers can also be classified as primary or secondary [105]. A primary plasticizer is required when more than one plasticizer is used (and it can also be used as a

Primary plasticizers: Primary plasticizers have the potential to improve polymer versatility effectively. The only plasticizer used is a main plasticizer, which is miscible with the
So, they are called true plasticizers or primary plasticizers. If only amorphous areas are penetrated, the compound acts as a nonsolvent plasticizer. Also called a secondary

A primary plasticizer, when added to a polymer, causes elon-gation and softness to be increased. These changes are brought about by mech-anisms described in the following section. A
Phthalates and other plasticizers—small molecules added to PVC to impart flexibility—have raised numerous health concerns due to their tendency to migrate out of PVC,

Their labels indicated “refined,” yet they had high plasticizer concentrations: 2,900 ng/g ortho-phthalate and 12,000 ng/g other plasticizers in one; 3,000 ng/g ortho-phthalate and
Virgin biopolymers are often brittle and therefore need the addition of plasticizers to obtain the required mechanical properties for practical applications, for example, in bags and
- Why is plasticizer important?
- Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC. Therefore, plasticizers are the most important commercial application of PVC. However, plasticizers can leach out of flexible PVC, changing the performance of PVC with age and contaminating the environment.
- What makes a polymer a good plasticizer?
- It is nowadays established that good plasticization implies secondary bonds, also known as intermolecular forces, with the polymer. The attraction between plasticizer molecules and the polymer must be as strong as the interactions between molecules in the single components to generate an efficient polymer-plasticizer interaction.
- How does a plasticizer interact with a polymer?
- In CA, plasticizer-polymer interactions begin with the mixing step: the plasticizer first wets the polymer particles and then diffuses and solvates the amorphous domains of the polymer thanks to externally added heat (e.g., heating jacket on the mixer) or heat generated internally by the friction between macromolecules.
- Do polymeric plasticizers have a low plasticizing efficiency?
- Unfortunately, they did not try them to PVC. In general, their large molecule size hinders diffusion in PVC to suppress migration. However, the rate of diffusion of the plasticizer is one of the most important factors determining plasticizer efficiency 33, 34. Polymeric plasticizer generally has low plasticizing efficiency.
- Why are plasticizers added to ca?
- Plasticizers are added to CA to increase workability, prevent degradation under processing conditions and ensure thermo-mechanical properties suitable for the intended final application. Moreover, inexpensive and non-toxic solvents enable its processing into fibers, films, and solid blocks.
- What are the different types of plasticizers?
- These include brominated phthalate plasticizers, triaryl, and alkyl aryl phosphates. These products are blended with other plasticizers to strike a balance between flame resistance, physical properties, and cost. Chlorinated paraffins, acting as secondary plasticizers reduce flammability and smoke.
