Ionic liquids as PIN FRs for a range of polymers, offering fire resistance and low impact on performance and processing. The ionic liquids, based on salts in which one ion has delocalised charge and one component is organic and biodegradable, contain phosphorus,...
A biopolymer extracted from seaweed wins University of Waterloo, Canada, place in James Dyson student Awards. The AlgoBio AlgoGel product consists of the natural biopolymer loaded with nanoparticles (not specified), producing a “non-toxic” liquid PIN FR for...
A reactive phosphorus – nitrogen PIN FR improved both fire performance and mechanical properties in flexible PUR foam. A complex dihydroxy P – N molecule 2- (( bis (2-hydroxyethyl) amino) methyl) -5,5-dimethyl -1,3,2-dioxaphosphinane 2-oxide (HAMPP) was synthetised in...
A polymeric phosphorus – nitrogen PIN FR was synthesised without using solvent achieving UL 94 V-0 in PLA at 2% loading. The polyphosphoramide DM-H was synthesised in a two-step, one-pot controlled condensation reaction, without solvents or catalysts, using HAD...
A novel PIN FR achieved fire and mechanical performance comparable to a brominated/antimony FR package. In polypropylene, a novel mono-constituent, intumescent PIN FR (PNP1D, combining phosphate ester, polyhydroxyl and melamine) was compared to DecaBDE or DecaBDE+HBCD...
