New water soluble phosphazene for textiles

New water soluble phosphazene for textiles

Poly- and cyclo- phosphazenes are recognised effective PIN flame retardants, but to date are not available as water soluble and permanent systems for textiles. Here a new cyclophosphazene was synthesised in a one-step process: hexa (allylamine) cyclotriphosphazene...

Systemic analysis of P-N flame retardant design

Four comparable phosphorus-containing compounds were synthesised, each with one central P atom and three hexenyl groups: an amide (P bonded to 3xN), a diamidate (P bonded to 2xN, 1xO), an amidate (P bonded to 1xN, 2xO) and a phosphate (P bonded to 3xO). These were...

Fire safety for polyurethanes

Rolf Albach, Covestro Covestro sees fire safety as an increasing challenge in all applications of plastic foams, in particular in buildings, where such foams offer the best insulation performance, cost effectiveness and adaptability of materials available. At this...
Innovative FRs for textiles and fibre-compounds

Innovative FRs for textiles and fibre-compounds

Jelena Vasiljević, University of Ljubljana, presented tests of three DOPO derivatives as additive PIN FRs in polyamide 6 fibres. The FRs were added in the caprolactam melt before polyamide polymerisation. Only PHED proved compatible with the melt extrusion process...
