“…The loss modulus (G") reflects the viscous behavior (liquid-like properties) of the polymer and represents the ability of a material to dissipate energy, while the storage modulus (G') is a measure for its elasticity (solid-like properties) showing the ability of the polymer to store energy [36].…”

Through a straightforward approach, a new meltable, halogen-free, nitrogen-phosphorus-based flame retardant (FR), 6-(2-(4,6-diamino-1,3,5-triazin-2-yl)ethyl) dibenzo [c,e][1,2]oxaphosphinine 6-oxide (DTE-DOPO) was synthesized and incorporated in polyamide 6 (PA6).It was proved that a very low phosphorus content of 1.46 wt % for DTE-DOPO additive improved the flame retardancy of PA6, leading to a non-flammable material. The performance of the new additive was compared to that of the commercially-available Exolit OP 1230. The PA6 formulations were evaluated by measuring the rheological, mechanical, and flammability behavior. Using compounding by melt extrusion, 17 wt % additives was introduced into PA6 matrix and the corresponding formulations were characterized. The results evidenced a higher homogeneity of DTE-DOPO with PA6, a high thermal stability with a catalyzing decomposition effect on PA6 caused by the presence of the new developed FR, enhanced elasticity for the PA6/DTE-DOPO formulation and a V0 rating for both formulations. Thermal and fire analysis indicated a primary gas-phase activity, combined with a complete suppression of the self-sustained burning for the PA6/DTE-DOPO formulation.Polymers 2015, 7 1542

“…27,65 The flame-retardant characteristics analysis can be done using the Limiting Oxygen Index (LOI), horizontal flame spreading test (flammability), energy dispersive spectrum and optical smoke density chamber (visible smoking, ignition and charring) and especially by Cone-calorimeter. 64,66 Chigwada Grace (2003) 52 showed that smoke-generating properties can be determined using the National Bureau of Standards (NBS) smoke burner chamber, and using tests performed in accordance with ASTM Test Method E662-09. Heat release rate tests are conducted using the Ohio State University test chamber and are carried out in accordance with ASTM Test Method E906-2010.…”

“…An LOI of greater than 26 is the required standard mark for establishing a self-extinguishing nature. 66 Some other fire retardant tests can also be adopted, e.g. UL94 (Underwriters Laboratories), vertical and horizontal flame retardancy 64 – 66,68.…”

Despite significant progress having been made in the study of flame retardancy of cellulosic building materials, the quest to find the ideal flame retardant material still continues. This review paper explores various options to substitute halogenated flame retardants by halogen-free alternatives in green building materials. Conventional flame retardants do not chemically react with cellulosic building materials such as bamboo. Owing to this, they remain an extraneous part of the substrate and could easily leach out due to various factors leading to low efficiency of the flame-retardant action. Durability of flame retardancy can be ensured by applying an additive that would chemically react with at least one of the ingredients of the green building material so that the flame retardant would remain an inherent part of the substrate. This paper also describes the reaction mechanisms of various treatment methodologies for ensuring the efficacious actions of non-halogenated flame retardants in green building materials such as wood and bamboo.
