“…For the PA6/Exolit formulation, T max1 observed at 424˝C may be attributed to the destabilization of polymer chains caused by the decomposition or volatilization of the additive, while T max2 may be due to the degradation of the system. Such a phenomenon is common for gas-phase active FR for PA6 due to the fire inhibition mechanism of the additives, being attributed by other authors to the formation of volatile diethyl phosphinic acid following the decomposition of its aluminium salt [40,42]. Both PA6 formulations promoted char formation at 700˝C while the absence of the residue in the case of neat PA6 polymer indicated the total decomposition of polymer into gaseous products.…”

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

“…Recently announced mixtures of phosphinates and other phosphorus compounds [10][11][12][13][14] have enabled Devan to develop for PP a novel flame retardant masterbatch. The aim of this article is to present the main results obtained by using this new mixture of phosphinates (MPh), in combination with classical nitrogen synergist agent, melamine cyanurate (MC), in different polypropylene textile structures.…”

Abstract:The efficiency of new phosphinates, in combination with melamine cyanurate, was studied using different polypropylene textile structures. The influence of different ratios up to a total amount of 6 wt% in the polypropylene fiber was investigated using the limiting oxygen index (LOI) and cone calorimeter method for research purposes, while the performances were correlated to the standards FMVSS 302 (Federal Motor Vehicle Safety Standards) and DIN 4102-l (Deutsches Institut für Normung) used more specifically for automotive and building sector.
