1. Introduction Poly(vinyl chloride) (PVC) is the second widely-used polymer globally, and plays a significant role in the global plastic market owing to its low cost. 1 Pure PVC has two disadvantages: easy brittle fracture and poor thermal stability. 2,3 In terms of mechanical properties, PVC is prone to brittle fracture, so it needs to be mixed with a large amount of plasticizers to improve
Recent Attempts in the Design of Efficient PVC Plasticizers with
Plasticised PVC grades are used for the production of hoses and cable insulation, liners, and all kinds of films, e.g., for packaging and blood bags. ... Modification of Poly (vinyl chloride)...
Triacetin as a Secondary PVC Plasticizer | SpringerLink
The use of biobased plasticizers with low toxicity and good compatibility with polyvinyl chloride (PVC) has become more attractive in the recent years in contrast with phthalate derivatives. 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

plasticizer selection. For most flexible applications, in-service plasticizer evaporation is the essential parameter that drives finished product durability. Jayflex DINP and DIDP plasticizers exhibit the lowest level of volatile losses and therefore the highest level of permanency. Maximum weight loss or change of mechanical
- Does plasticizer improve the thermal stability of PVC?
- It is obvious that the addition of plasticizer significantly improves the thermal stability of PVC, which should be attributed to the good thermal stability of the ester group. PEE has a macromolecular structure, and the strong intermolecular interaction further improves its thermal stability, resulting in a better improvement effect than DOP.
- Is PVC a good plasticizer?
- Thermal stability studies showed that PVC blends with HPGs were more stable (exhibiting higher onset temperature values on TGA curves) than samples with DEHP. A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance.
- Is macromolecular PVC plasticizer better than DOP?
- The macromolecular PVC plasticizer showed good plasticization effect. Although its plasticization efficiency was lower than DOP, the macromolecular plasticizer endowed PVC good thermal stability, high migration resistance.
- Does a mixture of Plasticizers improve the mechanical properties of PVC?
- Moreover, the mechanical properties were improved when a mixture of plasticizers was applied in PVC blends, whereas a blend with pure SOHE showed worse mechanical properties (lower elongation at break and higher tensile strength) than DOP.
- Do plasticizers migrate from PVC to DOP?
- As expected, the migration of plasticizers was equal to zero. Mechanical properties of the material with modified PVC were compared to a material plasticized by DOP. The commonly used plasticizer provided significantly lower tensile strength and higher elongation at break than the modified one.
- 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.
