Analysis and toxicity testing of combustion gases 2. Characterisation of combustion products from halogen-free flame-retardant duroplastic polymers for electronics

Fire Retarded Insulating Sheets from Recycled Materials

“…[11] The flammability of urethane foams was proposed to be decreased recently by increasing the proportion of isocyanurate in the composition. [12][13][14][15] Hauk et al [16] proposed a possible reactions mechanism for the combustion process of a poly(aminoarylisocyanurate) containing thermoset resin. In contrast to its good flame-retardancy CYA has quite poor mechanical properties because of its heterogeneous structure, shown in Fig.…”

Cure behavior and thermal degradation mechanisms of epoxy and epoxy-cyanate resins

“…Thus, aniline, diethyl aniline and, diisopropyl aniline have been identified. These molecules probably stemn from nonreacted , secondary CHÐOH or tertiary CÐOHÐ alcohol have been observed [14,15]. The overlapping of the 1000±1750 cm…”

Thermal degradation of cellulose acetate in presence of bis-phosphoramidates

“…10). In comparison the EC 50 value of phenol, considered as a substance of intermediate toxicity [28] is about 100 times lower. The two tested bis-phosphoramidate s were also significantly less toxic than N-hydroxymethyl-3-dimethylphosphonopropionamide (HDPP) which is a widely used commercial flame retardant for application on cellulose based fibers [29].…”

“…The two tested bis-phosphoramidate s were also significantly less toxic than N-hydroxymethyl-3-dimethylphosphonopropionamide (HDPP) which is a widely used commercial flame retardant for application on cellulose based fibers [29]. The synthesized phosphoramidates are also 100 times less toxic than the combustion gases from halogen-free flameretardant based on oxazolidinone and isocyanurate structures as well as phosphonate elements [28]. Microtox tests have also been previously carried out on organophosphorus compounds, such as phorate and terbufos which are often used as pesticides.…”
