Plasticizers: Types, Uses, Classification, Selection & Regulation
A secondary plasticizer is one that typically cannot be used as the sole plasticizer in a plasticized polymer. Secondary plasticizers may have limited compatibility with the polymer and/or high volatility. They may or may not contain functional groups which allow them to solvate the polymer at processing temperatures.

Triacetin as a Secondary PVC Plasticizer | SpringerLink
In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC. TAG was added to PVC formulations from 10 up to 20 phr. The increase of the plasticizer content had a great influence on the properties of PVC samples.
Classification of plasticizers - Oxoplast
Secondary plasticizers contain groups which are less polar. They demonstrate limited solubility and compatibility with PVC, that is why they are often used in mixtures with primary plasticizers. Such mixtures show a reduced tendency to migration, but increased strength at reduced temperatures and resistance to precipitation.
Plasticizer for poly(vinyl chloride) from cardanol as a
This high purity esterification was obtained using, 7 g of cardanol and 6.57 ml (7.09 mol, 3 equivalents) of acetic anhydride, diluted in 5 ml di pyridine, and held for 2 h at 50 °C. Then, the solution was washed with HCl aqueous solution, dried, and filtered.
- What are secondary plasticizers?
- Secondary plasticizers are additives which, when combined with the primary plasticizers, can improve the properties of the final material . In the present work, a glycerol derivative (triacetin—TAG) was used as PVC secondary plasticizer.
- Is glycerol a secondary plasticizer for PVC?
- In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC. TAG was added to PVC formulations from 10 up to 20 phr. The increase of the plasticizer content had a great influence on the properties of PVC samples.
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
- Is tag a suitable plasticizer for PVC?
- TAG has been used as a secondary plasticizer for PVC as a substitute or complement for traditional secondary plasticizers. The mechanical and thermal properties of the PVC formulations produced using TAG as plasticizer have been evaluated. The results suggested that TAG is a suitable plasticizer for PVC.
- Which substituent has the highest plasticization efficiency?
- The highest plasticization efficiency was observed with substituents consisting of soft segments between the bulky moiety and the cellulose chain compared to soft segments located at the end of the bulky groups directly attached to the cellulose chain. Besides, longer middle segments were more effective in decreasing the Tg.
- 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.
