ABSTRACTRigid polyurethane foam (RPUF) composites with triphenyl phosphate (TPhP), aluminum trihydrate (ATH), and zinc borate (ZnB) alone, as well as their binary blends, were prepared via a one‐shot process. The amount of flame retardant (FR) or FR blend was varied from 10 to 50% by polyol weight percentage, and the weight fraction of the blends was ...

ABSTRACTA novel flame‐retardant composite was prepared by introducing a phosphorus‐nitrogen flame retardant and DOPO‐SiO2 into PA6. DOPO‐SiO2 was synthesized successfully in a one‐step process. PA6/OP1314/DOPO‐SiO2 achieved a UL 94 V‐0 rating with an LOI value of 31%.

Benzoxazine monomers of traditional bisphenol‐A benzoxazine (BA‐a) and bisphenol‐A benzoxazine containing trialkoxysilane (BA‐a‐Si) were synthesized and incorporated into polyoxymethylene/ammonium polyphosphate/melamine (POM/APP/ME) to improve the fire retardancy of POM.

Polypropylene (PP) is one of the five kinds of universal polymers that have greatly improved our life qualities. While a pestilent limitation of PP is its flammability. Usually, halogen-containing flame retardants (FRs) are used to improve its flame retard ability.

Polymer Degradation and Stability, 2002
Abstract A hyperbranched polyurethane acrylate containing phosphorus was found to display flame retardance with a limiting oxygen index of 27.0 after being UV cured. The retardant mechanism was investigated by observing the site where retardance take places and the synergistic effect of phosphorus and nitrogen.

The epoxy asphalt (EA) binder has been widely used for the pavement on the steel plate deck and in tunnels. In this study, horizontal burning and limiting oxygen index (LOI) were conducted to evaluate the effects of mixed decabrombromodiphenyl ethane (DBDPE) and antimony trioxide (Sb2O3) on flame retardancy for epoxy asphalt binder.

Proceedings of the International Conference on Fire Safety Engineering Research and Practice
Flame-retardant (FR) chemistry of epoxy resins (EP) is microscopic and sophisticated, where retardant additives are engineered at the local polymer chains to facilitate carbonisation and radical exchanges during pyrolysis. Although analyrical experiments have been extensively performed to elucidate the thermal degradation characteristics of FR ...

A phosphorus‑nitrogen synergistic flame retardant (named POI) was obtained by the chemical reaction between phenylphosphonic acid (PPOA) and polyethyleneimine (PEI), and used to give the flame retardancy of PTCO. The effects of PPOA and POI on various properties of PTCO were investigated. PPOA obviously improved the flame retardancy of PTCO/PPOA, while
