Triazine macromolecule containing intumescent flame retardant polyolefin
2009 IEEE 9th International Conference on the Properties and Applications of Dielectric Materials, 2009A new triazine macromolecule was synthesized by using cyanuric chloride, ethnolamine and ethylenediamine. It is used as both a charring agent and a foaming agent in intumensect flame retardant, named as novel charring-foaming agent (CFA). CFA has a good ability of char formation itself.

Intumescent flame retardant systems of modified rheology
Polymer Degradation and Stability, 2002Abstract A model system of intumescent flame retardants, consisting of ammonium polyphosphate and pentaerythritol was prepared and investigated in polypropylene and without the polymer matrix. Thermal scanning oscillation rheometric investigation in the temperature range of 170–500 °C was used to detect the rheological behaviour in the region of ...

Effect of nickel phytate on flame retardancy of intumescent flame retardant polylactic acid
Polymers for Advanced Technologies, 2020Biodegradable polymers with flame retardancy have aroused great interest in the fabrication of biobased flame retardants. In this study, nickel phytate (PA‐Ni) was prepared by reaction of phytic acid from plant seeds with nickel acetate in water and then used as flame retardant added into polylactic acid (PLA) with intumescent flame retardant (IFR ...

Synthesis of a novel intumescent flame retardant and its flame retardancy in polypropylene
Journal of Polymer Research, 2010Microencapsulated 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).

Intumescence‐Based Flame Retardant
2021This chapter reviews the applications of intumescence in the field of fire protection (resistance to fire) and fire retardancy (reaction to fire) of material. It starts describing the basics of intumescence and gives the main intumescent products available on the market associated with their typical application’s fields.

A series of flame-retarded thermoplastic poly(imide–urethane)s (TPIUs) with either ammonium polyphosphate (APP) alone or APP and dipentaerythritol (DPER) have been prepared. The fracture strength and strain of TPIU composites decrease with increasing amount of intumescent flame retardant (IFR), as shown by tensile tests.

Bio‐Based Intumescent Flame‐Retardant Coatings for Enhanced Polypropylene Flame Retardancy
Journal of Applied Polymer ScienceABSTRACTPolypropylene (PP), as a widely used plastic, has its safety limited by its flammability. In response to the demand for sustainable development, this study has developed a bio‐based intumescent flame retardant (IFR) system composed of phytic acid (PA), sodium phytate (PA‐Na), and calcium gluconate (CG), which has been applied to the surface of ...

Synergistic flame‐retardant effect of halloysite nanotubes on intumescent flame retardant in LDPE
Journal of Applied Polymer Science, 2013AbstractSynergistic flame‐retardant effect of halloysite nanotubes (HNTs) on an intumescent flame retardant (IFR) in low‐density polyethylene (LDPE) was investigated by limited oxygen index (LOI), vertical burning test (UL‐94), thermogravimetric analysis (TGA), cone calorimeter (CC) test, and scanning electronic microscopy (SEM). The results of LOI and
