Researchers tested a sulphur polyphosphonate PIN flame retardant in PET achieving UL 94 V-0 (3.2 mm) at 8% loading but with dripping. The polysulfonyldiphenylene phenylphosphonate (PSPPP, a polyphosphonate) was synthesised by reacting phenylphosphonic dichloride with...
Magnesium hydroxide (MDH) treated with polydopamine and metal ions showed improved fire performance effect in epoxy. Polydopamine, a bio-inspired polymeric coating material, was polymerised in the presence of the well-recognised mineral PIN flame retardant MDH and of...
Biobased PIN flame retardant reduces heat and smoke release from epoxy by over one third. Waste peanut shells were pyrolysed at 700°C, to produce biochar, which was then combined with phytic acid (a natural phosphorus rich molecule widely present in plant seeds) and...
Mineral nitrogen FR flame retardants in wood function as indoor air purifier, removing oxygen ions. The natural mineral tourmaline (an acyclic silicate containing metals such as Na, Ca, K, Mg, Fe, Al, Li) and KH550 (a silane: 3-aminopropyl-triethoxysilane) were vacuum...
Lab tests of six aryl phosphate FRs in PC/ABS show reduced fire hazard but increased smoke emission and fire gas toxicity. Six different aryl phosphate PIN FRs (TPP, CDP, RDP, BTPP, BDP and Sol-DP) were tested at 10% w/w loading in 8:1 PC/ABS, with also PTFE anti-drip...
