Methyl Acetyl Ricinoleate as Polyvinyl Chloride Plasticizer
modified castor oil has been tested as PVC flame-retardant plasticizer and it was reported that incorporation of these novel plasticizers had improved the flame retardant prop-erties of PVC blends, as well as improved its migration stability [24–28]. In this work, MAR was used as a PVC plasticizer in sub-stitution of the traditional plasticizers.
Synthesis and Application of Phosphorus-containing Flame
A novel phosphorus-containing flame retardant plasticizer (PFRP) derived from castor oil acid methyl ester (COME) was synthesized to substitute dioctyl phthalate (DOP) for plasticizing polyvinyl chloride (PVC) products. The chemical structures of PFRP were confirmed by fourier transform infrared spectroscopy (FTIR) and 1H nuclear magnetic resonance (1H NMR). Meanwhile, the plasticizing effect
An Overview of the Flame Retardants for Poly(vinyl chloride
Over the last decade, multifarious flame retardants and smoke suppressants were developed for PVC materials. In this review, combined literature with the results based on the research from our group, recent emerged flame retardants and smoke suppressants for PVC are introduced.
Fire and flame retardants for PVC - William Coaker - 2003
In the case of flexible PVC, the plasticizers that contribute flexibility in most instances detract from its resistance to fire. To meet specifications such as oxygen index, heat release, smoke evolution, or extent of burning in cable tests, flame-retardant (FR) and smoke-suppressant (SS) additives are often incorporated.

FLAME SPREAD . The tendency of a material to spread a flame away from the fire source is critical to understand the potential fire hazard. Flame spread tests are used with the materials themselves or with the products in diverse applications (such as textiles or electrical insulation), preferably with all components of an assembly.

- What are eco-friendly PVC flame-retardant plasticizers derived from renewable sources?
- Eco-friendly PVC flame-retardant plasticizers derived from renewable sources have received affection. A series of biobased flame-retardant plasticizes has been prepared from castor oil with phosphaphenanthrene (DOPO) and diethyl phosphate , , , , , .
- Are STPD plasticized PVCs a flame retardant plasticizer?
- Weight loss of plasticized PVCs samples (A) under atmosphere at 180 °C for 2 h, and (B) in n-hexane at 50 °C for 2 h (STP 3 D, STP 3 and SP 3 D were used as the representatives, WRpl/PVC = 0.4). 3.3. Flame retardancy of STPD plasticized PVCs The potential of STPDs as flame retardancy plasticizers of PVC was further studied.
- Are flexible poly (vinyl chloride) plasticizers flammable?
- Nevertheless, the combustibility of flexible poly (vinyl chloride) (PVC) products containing high content plasticizers is frequently disregarded. The development of PVC functional plasticizers requires careful consideration of a good balance between flame retardancy, migration resistance and plasticity through molecular structure design.
- Does cardanol phenylphosphonate impart flame retardant and plasticizing effect in PVC?
- However, only a few reports are available on cardanol-based additives that impart flame retardancy and plasticizing effect into PVCs. Herein, we described a bio-based flame-retardant plasticizer, bis (cardanyl) phenylphosphonate (CP), which simultaneously acts as a flame retardant and plasticizer for PVC.
- Which PVC plasticizer is best?
- The plasticizer with good plasticity, flame retardancy and migration resistance. VA8-P plasticized PVC exhibits good plasticity at low temperature. VA8-P plasticized PVC obtains the UL-94 VTM-0 grade, superior to DOP. VA8-P plasticized PVC migrates very little in organic solvents.
- Are stpds eco-friendly and flame-retardant plasticizers for flexible PVC applications?
- The underlying flame-retardant mechanism, attributed to the synergistic effect of isocyanurate, DOPO, and PCL, was thoroughly elucidated. This work demonstrates that STPDs represent a promising class of eco-friendly, high-performance flame-retardant plasticizers for flexible PVC applications. 1. Introduction
