Long- and short-term stability of plasticized poly(lactic
The incorporation of plasticizers to the PLA not only improves its ductility but also enhances its processability. On the other hand, they result in lowering of the modulus and yield strength of PLA. Besides, one of the most important drawbacks of the plasticization is the migration of the low molecular weight plasticizer to the surface of the
Eastman Product List for General Purpose Plasticizers
Eastman plasticizers have served as highly effective non-phthalate replacements for other general-purpose plasticizers, such as DOP/DEHP and DINP. Our solutions add value to formulations by adding excellent viscosity stability, low-temperature resistance, and nonmigratory properties.
Perspectives on alternatives to phthalate plasticized poly
The most widely used PVC plasticizers are phthalate esters, particularly di-(2-ethylhexyl) phthalate (DEHP), which usually represent up to 40–50% of the weight of the plastic items. Phthalates account for 80% of all plasticizer production [6] while DEHP is responsible for over 50% of worldwide phthalate production [7].
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto
- What is re-placement of Di(2-ethylhexyl) phthalate (DEHP) plasticizer?
- ABSTRACT: Environmental and toxicity concerns dictate re-placement of di(2-ethylhexyl) phthalate (DEHP) plasticizer used to impart flexibility and thermal stability to polyvinyl chloride (PVC).
- Are phthalate esters a good plasticizer?
- Phthalate esters are still the most powerful plasticizers and dominate the plasticizer market due to their great plasticizing effect and low-cost, although phthalate plasticizers can migrate to the surface, leading to material performance degradation and a negative influence on human health 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16.
- Are phthalate-free plasticizers safe?
- In response to consumer and regulatory pressures, developing nonmigrating or phthalate-free PVC is very active in past few years. Recently, some other plasticizers instead of phthalate plasticizers, such as biocompatible material and oligomer 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, have been reported without toxicity.
- Are phthalate plasticizers covalently bound to PVC?
- Pharmaceutical Research. 18 (12), 1760–1766 (2001). Navarro, R., Pérez, P. M., Gómez Tardajos, M. & Reineckeet, H. Phthalate plasticizers covalently bound to PVC: plasticization with suppressed migration. Macromolecules. 43 (5), 2377–2381 (2010).
- Are phthalate plasticizers toxic?
- Recently, some other plasticizers instead of phthalate plasticizers, such as biocompatible material and oligomer 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, have been reported without toxicity. However, compared to phthalate plasticizers, majority of them have a poor plasticizing effect and the plasticizer migration still cannot be avoided.
