Research progress of novel bio-based plasticizers and their
Many bio-based PVC plasticizers, such as vegetable oil-based plasticizers, cardanol-based plasticizers, lactic acid-based plasticizers, waste cooking oil-based plasticizers, polyester plasticizers, hyperbranched plasticizers and so on, have been extensively studied.
Nonphthalate Plasticizers in House Dust from Multiple Countries: An
Along with the restrictions of phthalate esters (PAEs), a variety of nonphthalate plasticizers (NPPs) have been increasingly used for industrial needs. Knowledge remains limited on the environmental occurrences, fate, and human exposure risks of many emerging NPPs. In this study, we investigated a suite of 45 NPPs along with the major PAEs in house dust from five regions in the Asia-Pacific
Recent Developments of Biobased Plasticizers and Their Effect on
Phthalates have been the most commonly employed plasticizers for PVC, but some of these plasticizers demonstrate many toxic effects on the environment and human beings, which consequently limits the use of phthalate plasticizers.
SciELO - Brasil - Synthesis and application of natural polymeric
In a glass beaker, 0.4 g of PVC K70 resin (Braskem, Brazil) was mixed with the natural plasticizer (30 wt% in relation to PVC resin) followed by the addition of 9 mL of tetrahydrofuran. The mixture was homogenized using a magnetic stirrer for 10 min at room temperature (25 C) and then the solution was casted in a clean Petri dish (diameter 14 cm).

Remarkably, the plasticizing effect of the curcumin derivatives in the PVC material was found to be similar to that observed in previous PVC-phthalate materials. Finally, studies applying these new materials in the photoinactivation of S. aureus planktonic cultures revealed a strong structure/activity correlation, with the photosensitive materials reaching up to 6 log CFU reduction at low
- Why are phthalate plasticizers becoming bioplasticizers?
- Owing to health concerns, depletion of crude resources and other factors, there is a gradual drift from traditional phthalate plasticizers to bioplasticizers in the plastic industry. Bioplasticizers are derived mainly from biomass sources including agricultural products, it’s by-products and waste.
- Why is Cargill a bio-based plasticizer?
- Today's consumers expect environmental consciousness as well as flexible PVC products that perform. Cargill has created a bio-based plasticizer that meets the rigorous regulations for the PVC industry without sacrificing performance or profitability.
- What are bioplasticizers derived from?
- Bioplasticizers such as epoxidized plant oils, cardanol, citrates and Isorbide esters are derived from further modifications of oils and triglyceride, starch and cellulose, citric acids and glycerol. By biomass sources, oils and triglycerides are obtained from oleaginous plants, starch and cellulose from cereals and citric acids from citrus.
- Where do natural plasticizers come from?
- Several natural plasticizers originate from agricultural products like trees, oleaginous plants, cereals, vegetables, and fruits, as well as their waste . Utilizing bio-based wastes as natural plasticizers, various polymers and materials have been tested.
- Are Cargill plasticizers better than phthalate?
- In lab testing, our chemistry indicated higher efficiency, faster processing, and compatabilty for PVC and other polymer applications when compared with phthalate-based options. Cargill plasticizers are high-performance compounds for the future of the footwear industry.
- Could liquefied wood flour derived plasticizer be a biobased polylactide plasticizer?
- CONCLUSIONS: The results demonstrate that the synthesized liquefied wood flour derived plasticizer could have great potential as a biobased polylactide plasticizer. © 2012 Society of Chemical Industry PDF | Plasticizers are chemical additives added into polymers to influence desirable mechanical properties such as processability and ductility.
