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.
Effectiveness of triacetin and triethyl citrate as
It was found that, at a fixed amount of plasticizer (10%), TRI caused reduction of glass transition temperature (Tg) and melt temperature (Tm) in both PVA with the largest reduction in 88% hydrolysed PVA while TEC showed insignificant changes of Tg and slight reduction of Tm suggesting higher effectiveness of plasticization in 88% hydrolysed PVA

Triacetin has traditionally been used as a plasticizer in many applications. In polyvinyl acetate (PVAc) systems, triacetin is very effective in T g reduction and facilitates desired viscosity increase in the final emulsion (see chart below). Triacetin is very similar in performance to other common plasticizers, but

- Is tri a good plasticizer?
- A few researchers incorporated TRI or TEC as plasticizer in polymers such as PLA [7, 8] and PVC with reported reduction of glass transition temperature and melting temperature suggesting improvement in flexibility and processibility.
- Is glycerol a secondary plasticizer?
- In the present work, a glycerol derivative (triacetin—TAG) was used as PVC secondary plasticizer. The PVC formulations were characterized by tensile strength, shore A hardness, density, MFI, DMA and TGA to evaluate the effect of this environmentally friendly plasticizer on the performance of the PVC formulations.
- How is triacetin produced?
- Triacetin (TAG) can be obtained by acetylation of biodiesel glycerol (see Scheme 1) using acetic acid or anhydride acetic. The efficient and selective acetylation of glycerol can be achieved in the presence of magnetic solid acids as catalysts . Moreover, it can be produced from the glycerol derived from the biodiesel production.
- Can glycerin acetate be used to plasticize PVC?
- The use of glycerol derived plasticizers has been reported to provide PVC with excellent mechanical properties . Mixtures of glycerin acetates have been reported to afford the same plasticization efficiency as di (2-ethylhexyl) adipate) (DEHA) .
- 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 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.
