Synthesis and Properties of Isosorbide-Based Eco-friendly
Solubility parameters (δ) of the plasticizers were calculated according to Small’s cohesive energies [ 35 ], and epoxy values of the synthesized plasticizers were calculated according to ASTM D1652-04. The PVC specimens were prepared as type IV dumbbell-type, according to ASTM D638.
Natural-based plasticizers and biopolymer films: A review
Other important factor is solvation, as plasticizers with solubility parameters close to those of the polymer require less energy to fuse or solvate the polymer. The temperature of fusion or gelation is related to the solvation strength of the plasticizer and to the size of its molecule [4].
Interfacial effects of plasticizers on the properties
Glycerin (GL), diacetin (DA), triacetin (TA) and polyethylene glycol (PEG) were chosen as the green candidate plasticizers for CDA, because they are environmentally sustainable (“eco-friendly”) plasticizers with low toxicity (Lee et al. 2006a, b; Rao and Diwan 1997 ).
Title: A Review on Plasticizers and Eco-Friendly
Various efforts for producing more eco-friendly plasticizers have been carried out by using biobased sources such as diester succinates, which display better biodegradation behavior and...
Plasticizer for poly(vinyl chloride) from cardanol as a
The Hansen solubility parameter of PVC and plasticizer can be obtained as the sum of three contributions: (4) δ = ( δ d 2 + δ p 2 + δ h 2) 0.5 Where δ d is the contribution of dispersion forces, δ p is the contribution of permanent dipoles, and δ h is the contribution of hydrogen bonding.
- Are isosorbide-based plasticizers eco-friendly and effective?
- In this study, isosorbide-based eco-friendly and effective plasticizers were synthesized and characterized. Isosorbide esterification was conducted using f
- Are plasticizers environmentally friendly?
- Four environmentally friendly plasticizer samples were obtained; their chemical structures and compositions were confirmed by gas chromatography (GC) and infrared spectroscopy (FT–IR) analyses, and their physicochemical properties and thermal stability (TGA analysis) were investigated.
- Is isosorbide di epoxidized oleate a green plasticizer for PVC processing?
- To the best of our knowledge, this is the first study to introduce isosorbide di epoxidized oleate as a green plasticizer for PVC processing. Here, isosorbide was esterified with a series of fatty acids, and the isosorbide diester plasticizer with short alkyl chain length showed high compatibility with PVC.
- How does a plasticizer improve the processability of a polymer?
- A plasticizer improves the processability of a polymer, without distorting its basic structure and physical properties. The plasticizer penetrates the polymer chains, weakens the interchain attraction, and increases the free volume, facilitating chain movement.
- Can plasticizers replace petroleum-based plasticizer in PVC applications?
- Compared to DINP and DEHP, the migration was as much as 70% lower for each plasticizer concentration. Thus, due to their good compatibility, efficiency and thermal properties, the plasticizers synthesized in this research have the potential to replace petroleum-based plasticizers in PVC applications.
- Can bio-based plasticizers be synthesized by modifying fatty acids?
- In this study, bio-based plasticizers were synthesized by modifying fatty acids with very user-friendly approaches. Esterification and epoxidation were used to synthesize bio-based plasticizers in two steps. The synthesized plasticizer is blended with PVC in various amounts and compared to dioctyl phthalate (DOP).
