New Vinyl Epoxy Plasticizers | C&EN Global Enterprise
The compounds, for which peracetic acid is the epoxidizing agent, may answer the crying need for a greater variety of epoxy plasticizers and stabilizers. To date only two epoxy classes have commercial status: epoxy fatty acid esters and the glycidyl ethers. FMC's Frank P. Greenspan estimated to the Division of Paint, Plastics, and Printing Ink
Synthesis and application of a novel environmental C26
Most of the major commercial plasticizers are esters, which allow specific polymer interactions (electrostatic, hydrogen bonds, or van der Waals) [1, 15]. The epoxy groups of the epoxidized plant oil-based plasticizers mentioned above can act as HCl scavengers and co-stabilizers to bring thermal stability to PVC . The present work, therefore
A sustainable poly (vinyl chloride) plasticizer derivated
Compounds derived from vegetable oil have been widely used as a plasticizer or secondary thermal stabilizer for PVC. For example, the effect of epoxidized soybean oil (ESO) as a plasticizer on the mechanical and thermal properties of PVC has been studied [Bouchareb and Benaniba, 2008].
Synthesis and Properties of a Novel Environmental Epoxidized
The functional epoxy groups in glycidyl esters are able to act as HCl scavengers and co-stabilizers, which can bring thermal stability to PVC [1]. The ester group in glycidyl ester allows specific
The Chemicals in Vinyl Flooring and Their Purposes | Brenntag
Vinyl stabilizers are typically metal compounds and may consist of a variety of substances derived from heavy metals. The primary heat stabilizers in a vinyl product may also be combined with other stabilizers made of organic materials such as epoxidized esters and polyols. Different stabilizer mixtures provide different qualities.
- Are epoxidized cardanol ester stabilizers suitable for PVC films?
- In this work, two different epoxidized cardanol ester stabilizers were synthesized, and their structures were characterized. Moreover, their synergistic plasticizing and thermal stabilization effects on PVC were studied, and PVC films with excellent mechanical and thermal stability were prepared.
- Does epoxidized cardanol glycidyl ether improve thermal stability of PVC?
- They found that compared with PVC plasticized by DOTP and DINP, PVC plasticized by CGE showed better thermal stability. Then, they continued to study the effect of epoxidized cardanol glycidyl ether (ECGE) on the plasticization and thermal stability of PVC [ 17 ].
- Does cardanol glycidyl ether plasticize PVC?
- Chen et al. [ 16] studied the plasticizing and thermal stability effect of cardanol glycidyl ether (CGE) on PVC. They found that compared with PVC plasticized by DOTP and DINP, PVC plasticized by CGE showed better thermal stability.
- Are organic heat stabilizers suitable for PVC?
- In recent years, environmentally friendly organic heat stabilizers have been prepared and developed for the heat stability of PVC. Wang et al. [ 8] studied tung-oil-derived imide epoxidized esters as a PVC heat stabilizer.
- Does polyvinyl chloride (PVC) need a heat stabilizer?
- The development of a heat stabilizer with good thermal stability, plasticizing performance, and migration resistance for polyvinyl chloride (PVC) is still a notable challenge.
- Do we need a stabilizer when processing PVC films?
- The results also illustrated the necessity of adding stabilizer when processing the PVC film. In the wavelength range of 200–400 nm, the PVC films stabilized by CaSt 2 /ZnSt 2 showed a superior ultraviolet ray blocking performance due to physical shielding of this stabilizer [ 35 ].
