A targeted review of bio-derived plasticizers with flame
The plasticizer used in this work is dioctyl phthalate, and flammability of the PVC samples is studied with LOI, UL-94 V testing (testing at 1.0 mm sample thickness), and cone calorimeter, using a heat flux of 50 kW/m 2 with 3 mm thick cone calorimeter specimens.

Firstly, PVC and additives (see Table 1) were premixed at 100°C in a mixing device at a mixing speed of 2400 rpm for 10 min then cool quickly to 50°C and continue to mix for 5 min and then incubate at room temperature in 24 hours. Secondly, the Haake PoLylab System Rheomix was used to mix.

The plasticizing effect of PHS was studied and compared with the traditional dioctyl phthalate (DOP) plasticizer. The results show that the PVC plasticized by PHS had the lowest tensile...
Soil burial degradation of new bio-based additive plasticized
Two plasticizers were used: dioctyl phthalate (DOP) and diisononyl adipate (DINA). A natural aging test on site in a garden soil (Tizi Ouzou, Algeria) of the PVC samples was investigated for 6 months.
Dioctyl Phthalate (DOP) Plasticizer - Fengbai Group
Dioctyl phthalate DOP, an organic ester compound, is one of the most commonly used plasticizers. DOP plasticizer is a transparent oily liquid with no visible impurities in appearance, which is insoluble in water, soluble in most organic solvents such as ethanol, ether, mineral oil, etc. As the most widely used plasticizer in industry, DOP as
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- Does phthalate enlarge the molecular weight of PVC?
- Unlike other reported methods, this approach increases the interaction between phthalate and PVC to suppress its migration, not simply to enlarge its molecular size (or molecular weight). This methodology is highly versatile for producing the desired non-leaching PVC with a permanent plasticizer effect.
- 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).
- How does cp52 affect plasticization efficiency?
- With higher DOP-O-CP52 levels in PVC, CP52 in DOP-O-CP52 will form microclusters owing to their lower compatibility with PVC, to retard the movement of DOP-O-CP52 in PVC, resulting in a decline in plasticizing efficiency. Figure 6 shown the extraction of plasticized PVCs.
- 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 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.
