Preparation and Performance of Bio-Based Polyol Ester
In this study, castor oil based polyol ester (CPE) was synthesized via a simple and efficient way and used as a sustainable plasticizer in poly (vinyl chloride) (PVC) films to replace toxic DEHP. The chemical structure of the obtained bio-based plasticizer was characterized.
A potentially general approach to aliphatic ester-derived PVC
The safety of flexible polyvinyl chloride (PVC) materials is now being questioned, partially due to allegations that di-(2-ethylhexyl) phthalate (DEHP), the dominant PVC plasticizer, is an endocrine disruptor and a probable carcinogen. As sustainable alternatives, aliphatic ester-derived plasticizers feature
Synthesis of Biomass Based Plasticizer from Linoleic Acid and
In this paper, we synthesized a kind of bio-based plasticizer epoxidized linoleic acid cardanol ester (ELCE) from cardanol and linoleic acid. Its chemical structure was characterized with FT-IR and 1 H NMR. Polyvinyl chloride (PVC) blends plasticized with ELCE were prepared via thermoplastic blending with torque rheometer.
Plasticizers Derived from Biomass Resources: A Short Review.
These bio-based plasticizers mainly include epoxidized plasticizer, polyester plasticizer, macromolecular plasticizer, flame retardant plasticizer, citric acid ester plasticizer, glyceryl ester plasticizer and internal plasticizer.
TGA curves of the PVC films with different plasticizers
A castor oil-based diglycidyl ester plasticizer (C26-DGE) was prepared by Chen et al. 17 with ricinoleic acid as raw material and results showed that the plasticizer endowed the PVC matrix with
- What is a safe plasticizer substitute for phthalate esters in PVC?
- Of all these options, vegetable oils (refined or used) and their derivatives, like fatty acid alkyl esters (biodiesel) and free fatty acids, are some of the most promising raw materials for producing safe plasticizer substitutes for toxic phthalate esters in PVC and other polymers [7, , , , ].
- Do epoxidized benzyl esters provide flexible PVC films?
- Epoxidized benzyl esters provided flexible PVC films with favorable properties. The objective of this study was to produce new and renewable bio-based plasticizers from used soybean cooking oil (USCO). First, USCO was completely converted into free fatty acids (FFAs) using lipase from Candida rugosa.
- Is 2-5-furandicarboxylic acid a biobased plasticizer for poly lactic acid (PLA)?
- This study addresses the synthesis of three esters from 2,5-furandicarboxylic acid with different alcohols to a one-pot reaction through acid catalysis to evaluate them as biobased plasticizers for poly (lactic acid) (PLA).
- What are natural based plasticizers?
- Nowadays, there is increasing interest in the use of natural-based plasticizers that are characterized by low toxicity and low migration. This group includes epoxidized triglyceride vegetable oils from soybean oil, linseed oil, castor-oil, sunflower oil, and fatty acid esters (FAEs) .
- Can eleostearic acid eugenol ester be used to plasticize PVC films?
- In this study, two kinds of sustainable plasticizers (eleostearic acid eugenol ester (EAEE) and epoxidized EAEE) were synthesized to plasticize PVC films using eleostearic acid and eugenol. Compared to EAEE, PVC plasticized with epoxidized EAEE showed more flexible and thermal stability.
- What is a nonmigrating plasticizer?
- Most prominently, hyperbranched oligomeric esters derived from the readily available, renewable, nontoxic biomonomers, glycerol and adipic acid, are excellent nonmigrating plasticizers. These materials may be produced in a simple process.
