Effect of Modified Cardanol as Secondary Plasticizer on
This study represents the first attempt to prepare a novel cardanol-based plasticizer. Modified cardanol (MC, i.e., phosphorylated cardanol) containing nitrogen and phosphoric acid groups was synthesized and then incorporated into polyvinyl chloride (PVC) as the secondary plasticizer for partial substitution of dioctyl phthalate (DOP).

Cardanol acetate (CA) can be used as secondary plasticizer, in addition to conventional plasticizers, for the production of soft PVC. Nevertheless, the migration of CA is very high compared to the migration of conventional phthalate plasticizers for PVC [20] , mainly due to the relatively low compatibility between the PVC and the relatively

Cardanol, an inexpensive by-product derived from cashew nut shell liquid, is considered as a promising alternative to design a green and low-cost plasticizer for PVC due to its unique structure and low-cost production.

Results of DMA, TGA and mechanicalanalysis indicated that CA can serve as a secondary plasticizer to improve the related properties of soft PVC formulations. These CD derived plasticizers show promise as an alternative to fully or partially replace petroleum-based plasticizers. Introduction
- Is there a novel cardanol-based plasticizer?
- ABSTRACT: This study represents the first attempt to prepare a novel cardanol-based plasticizer. Modified cardanol (MC, i.e., phosphorylated cardanol) containing nitrogen and phosphoric acid groups was synthesized and then incorporated into polyvinyl chloride (PVC) as the secondary plasticizer for partial substitution of dioctyl phthalate (DOP).
- Is cardanol a good plasticizer for PVC?
- CONCLUSIONS A novel cardanol-based plasticizer was synthesized in this study and then incorporated into PVC to improve the thermal, mechanical, and leaching stabilities. For this purpose, a commercially available plasticizer was partially substituted with MC.
- Does cardanol improve thermal stability of PVC blends?
- A novel cardanol-based plasticizer was synthesized in this study and then incorporated into PVC to improve the thermal, mechanical, and leaching stabilities. For this purpose, a commercially available plasticizer was partially substituted with MC. The thermal stability of PVC blends is increased significantly as the MC content increases.
- Can cardanol acetate be used as a secondary plasticizer?
- Moreover, the studies of migration resistance of new formulations were not conducted. An interesting application of cardanol derivatives as a secondary plasticizer was proposed by Chen et al. , who investigated a synergistic effect of cardanol acetate (CA) and DOTP.
- Can ECEP replace petroleum-based plasticizer in PVC films?
- The mechanical properties before and after aging analysis indicated the incorporation of ECEP could significantly increase the flexibility, toughness and thermal stabilities of the PVC films. Furthermore, ECEP is expected to partially or completely substitute petroleum-based plasticizer in PVC materials manufacturing.
- What is the chemical shift between cardanol and Penta decyl?
- The chemical shift at 1.2, 1.4, and 2.8 ppm is attributed to the methylene groups (label 7, 10, and 12) from the long side chain of the cardanol unit, whereas that at 0.7 ppm is attributed to the terminal methyl groups of dienes, monoene, and penta decyl moieties (label 13).
