Synergistic Effect of Montmorillonite and Intumescent Flame Retardant on Flame Retardance Enhancement of ABS

Polymer-Plastics Technology and Engineering, 2007
The synergistic effects of organic montmorillonite (OMMT) and intumescent flame retardant (IFR) based on the ammonium polyphosphate (APP) and pentaerythritol (PER) on flame retardant enhancement of acrylonitrile-butadiene-styrene copolymer (ABS) were investigated by using the limiting oxygen index (LOI), the UL-94 (vertical flame) test ...

Effect of Polyborosiloxane on the Flame Retardancy and Thermal Degradation of Intumescent Flame Retardant Polypropylene

Journal of Macromolecular Science - Physics, 2014
A novel synergistic flame retardant agent containing boron and silicon, namely polyborosiloxane (PBSil), was prepared via the condensation reaction of boric acid (BA), tetraethoxysilane (TEOS), and octamethyl cyclotetrasiloxane (OMCTS). The obtained PBSil was then combined with an intumescent flame retardant (IFR) to flame retard polypropylene (PP ...

The flame retardant and thermal performances of polypropylene with a novel intumescent flame retardant

Journal of Applied Polymer Science, 2020
AbstractA novel mono‐component intumescent flame retardant(m‐IFR), called poly‐(spirocyclic pentaerythritol bisphosphonate‐1,3,5‐triazine‐O‐bicyclic pentaerythritol phosphate) (PSTBP) was synthesized and characterized. PSTBP was used in polypropylene (PP) to obtain PP/PSTBP mixture whose flame retardancy, thermostability, and water resistance were ...

Synthesis of a novel intumescent flame retardant and its flame retardancy in polypropylene

Journal of Polymer Research, 2010
Microencapsulated ammonium polyphosphate (GMFAPP) is prepared by in situ polymerization method with a shell of poly(ethylene glycol) modified melamine-formaldehyde resin. Due to the presence of shell, GMFAPP shows less size, higher water resistance and flame retardancy in polypropylene (PP) compared with ammonium polyphosphate (APP).

Flame-Retardant Effect of Sepiolite on an Intumescent Flame-Retardant Polypropylene System

Industrial & Engineering Chemistry Research, 2011
Intumescent flame-retardant polypropylene-containing phosphorus and nitrogen compounds were enhanced significantly by adding a small amount of sepiolite as a synergistic agent. The flame-retardant polypropylene composite was characterized by limiting oxygen index (LOI), UL-94, the cone calorimeter (CCT), and thermogravimetric analysis (TGA) to study ...

Flame retardancy and thermal degradation of intumescent flame retardant polypropylene material

Polymers for Advanced Technologies, 2011
AbstractThe flame retardancy and thermal degradation properties of polypropylene (PP) containing intumescent flame retardant additives, i.e. melamine pyrophosphate (MPyP) and charring‐foaming agent (CFA) were characterized by limiting oxygen index (LOI), UL 94, cone calorimeter, microscale combustion calorimetry, and thermogravimetric analysis (TGA ...

Synthesis of in situ encapsulated intumescent flame retardant and the flame retardancy in polypropylene

Polymer Composites, 2007
AbstractIn this article, a nitrogen–phosphorus composite flame retardant, melamine phosphate (MP), was synthesized in a solution of phosphoric acid/macromolecular charring agent, polyamide 6 (PA6). With the progress of the phosphoric acid–melamine reaction producing MP, the acidity of this system decreased and the originally dissolved PA6 resin ...
