Research progress of novel bio-based plasticizers and their
Abstract Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing. Owing to the negative impact of petroleum-based plasticizers on human health
Performance assessment of polyvinyl chloride films
Mtt et al. (2007) [24] also studied the surface roughness of PVC films plasticized with different plasticizers (DOP, di-isononyl-cyclohexane-1, 2-dicarboxylate, and diethylene glycol monobenzoate) and observed roughness in the range of 0.03–0.1 μm. On that basis, they considered films have a better morphology with a smooth surface.
Tung oil based plasticizer and auxiliary stabilizer for poly
Tung oil was successfully converted into epoxidized dicarboxylic acid dimethyl ester (epoxidized-C21-DAE). Epoxidized-C21-DAE are introduced as primary plasticizer and auxiliary thermal stabilizer for poly (vinyl chloride) (PVC). The epoxidized-C21-DAE as a primary plasticizer for PVC significantly improved PVC thermal stability and flexibility.
The Epoxidized Vietnam Rubber Seed Oil as a Secondary
The epoxidized rubber seed oil (EeRSO) was a mixture of epoxidized triglyceride, and epoxidized methyl ester of free fatty acids was used as a secondary plasticizer for PVC. An increase in tensile properties was observed by substituting the 10 phr DOP plasticizer with the EeRSO in PVC formulation.

1. General purpose plasticizer [GP] - They provide desired flexibility to PVC, balancing overall quality with low cost. Examples are DIHP, DOP (DEHP), DINP and DIDP. They can be used along with
- Can bio-based plasticizers replace DOP?
- The bio-based plasticizers a and c derived from modified waste cooking oil using aromatic diacid could be used as temperature-resistant main plasticizers for the PVC to completely replace the DOP.
- Does DOP plasticizer percentage affect limiting oxygen index and thermal stability?
- The effect of DOP plasticizer percentage on limiting oxygen index and thermal stability of plasticised PVC was investigated in this paper. DOP was added PVC with various quantities (20, 30, and 50) pphr. LOI and thermal stability instruments used for estimating LOI and thermal stability of plasticised PVC as a function to DOP percentage.
- Does DOP increase the thermal stability of plasticised PVC?
- The results showed that the thermal stability of plasticised PVC was improved by increasing DOP percentage, but in the same time has a reverse behavior where the LOI decreases as the DOP percentage increases. Thermal stability test at temperature 190°C and 200°C respectful. Specifications of PVC S-5070 (Ongrovil ® ) .
- What are the mechanical properties of Bio-Base plasticizers?
- The structures of bio-base plasticizers (a, b and c) were confirmed by Fourier transform infrared spectroscopy (FT-IR), 1 H NMR and 13 C NMR. The mechanical properties of a/PVC were as good as those of PVC films with the dioctyl phthalate (DOP) plasticizer. Meanwhile, the elongation at break of c/PVC reached 422%.
- Is acetylated castor oil a bio-based plasticizer?
- Although acetylated castor oil has excellent performance as the bio-based plasticizer and has realized industrialized production, the price of it is three to four times more expensive than phthalates, which limited its utilization (Bocque et al., 2016).
- Which Bio-Base plasticizer has a better plasticizing effect at low temperature?
- The FT-IR of PVC films showed that the downfield shifts of the —CH—Cl groups of the PVC plasticized with a and c were greater than that of b/PVC. The bio-base plasticizers b had a better plasticizing effect at low temperature. 1. Introduction
