Clarifying the nomenclature of Elvaloy-based geomembranes
DuPont developed KEE to provide a solid plasticizer or polymer to replace liquid plasticizers that would make PVC and other polymers flexible without concerns of plasticizer migration and loss. Plasticizer migration and loss usually results in the material becoming stronger but more brittle and susceptible to cracking.
POE Alloys Replace Liquid Plasticizers In High-Performance
Flexible PVC formulated with the new PVC/POE alloy, with or without liquid plasticizer, is expected to be only 10% to 15% more expensive than conventional PVC, says Teknor's Morin. However, all the POE/PVC alloys have lower specific gravity than conventional PVC, which improves their economics.

The strategies to prevent plasticizer migration from PVC products mainly include internal plasticized method such as covalently attaching plasticizer onto the PVC matrix ; making surface modifications such as gamma irradiation, ultraviolet irradiation and plasma treatment ; and adding nanoparticles or ionic liquid [9,10].
Eastman Plasticizers for PVC
Benzoflex 354 is compatible with a wide range of synthetic resinous materials and imparts a softening and flexibilizing effect to these resins. It is suggested for use as a resin plasticizer/modifier in the formulation of specialty coatings and adhesives and polyvinyl chloride plastisols.

Hercoflex 707 is recommended for flexible vinyl applications requiring high-temperature performance and good processability. Hercoflex 600 is a pale, high-boiling liquid with extremely low volatility and reportedly excellent resistance to heat, light, and moisture.
- Is lactic acid based plasticizer suitable for PVC and PLA?
- In this paper, a lactic acid based plasticizer suitable for PVC and PLA was synthesized by a two-step esterification reaction with lactic acid as the main raw material, and compared with commercial plasticizers dioctyl terephthalate (DOTP), diisononyl cyclohexane dicarboxylate (DINCH) and diethylene benzoate (DEDB).
- How to evaluate the plasticizer effect of PVC & PLA blends?
- Its structure was characterized by 1 H NMR, FT-IR and TOF-MS. Thermogravimetric analysis (TGA), tensile test and leaching test were used to evaluate the plasticizer effect of PVC or PLA blends. Compared with commercial plasticizers, CTLE showed more outstanding thermal stability, flexibility and migration stability.
- 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.
- Which plasticizer can reduce TG of pure PVC?
- Secondly, the Tg of pure PVC is about 84.4 °C , so it is obvious that the four plasticizers could effectively reduce Tg respectively. Among them, CTLE had the most obvious effect of reducing Tg, which could reduce the Tg of PVC to 24.6 °C. The following are DEDB, DOTP and DINCH. It shows that CTLE is a potential new plasticizer.
- What are the different types of plasticizers?
- 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 when used in excess and usually added to the blend to improve its properties or to reduce its costs . Figure 1.
- Can plasticizers be replaced by new compounds?
- This paper reviews the current trends in replacing commonly used plasticizers in poly (vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in mechanical properties and better plasticizing efficiency. ...
