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 ...

Flame retardants: intumescent systems
1998Intumescent fire retardant additives undergo a thermal degradation process on heating, which produces a thermally stable, foamed, multicellular residue called ‘intumescent char’. When these substances are added to a polymeric material which is later involved in a fire, they produce an intumescent char which accumulates on the surface, while the polymer

A novel intumescent flame‐retardant system for flame‐retarded LLDPE/EVA composites
Journal of Applied Polymer Science, 2009AbstractA new intumescent flame retardant (IFR) system consisting of ammonium polyphosphate (APP) and charing‐foaming agent (CFA) and a little organic montmorillonite (OMMT) was used in low‐density polyethylene (LLDPE)/ethylene‐vinyl acetate (EVA) composite.

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

A novel macromolecular intumescent flame retardant (MIFR) was synthesized. Unsaturated polyester (UP) filled with MIFR as flame‐retardant additive was prepared. The effects of MIFR on properties such as tensile strength, impact strength, flame‐retardant behavior, thermal stability, and morphology of char were studied.

A novel intumescent flame retardant imparts high flame retardancy to epoxy resin
Polymers for Advanced Technologies, 2019Intumescent flame retardant (IFR) has received the considerable attention ascribed to the inherent advantages including non‐halogen, low toxicity, low smoke release and environmentally friendly. In this work, a novel charring agent poly (piperazine phenylaminophosphamide) named as PPTA was successfully synthesized and characterized by Fourier transform
