Triazines are environment-friendly nitrogen-based PIN flame retardants, generating char, inhibiting fire and reducing smoke. This paper presents different routes for synthesis of triazines, via the chlorinated agent CYC (cyanuric chloride) or from melamine, generating...
Reaction of P-esters into epoxy generates a thermally recyclable polymer with fire performance and low smoke. The phosphorus ester TDPSD* was synthesised from diphenylphosphite, then reacted with epoxy DGEBA in a one-pot, two-step process without using solvents. This...
Expandable graphite (EG) enhanced fire performance and reduced smoke with magnesium hydroxide in polypropylene. Polypropylene was tested with 0 – 63% magnesium hydroxide (MH), 9 – 30% EG and a combination of 4 – 17% EG with MH to a total of 57% PIN FR. Replacing c....
Despite extensive studies available, further data is needed on breakdown products of novel brominated and organo-P FRs in fauna. This review of 150 publications concludes that metabolism pathways of organo-phosphorus flame retardants are similar in different animals...
Some 18 000 cows died and a worker was seriously injured in a fire on a Texas dairy farm, 10th April 2023. The fire may have started in a slurry pumping machine, possibly leading to an explosion of methane gas released from manure. This is the deadliest “barn fire”...
