The organophosphorus PIN FR DOPO-diamine was reacted into PLA and polyurethane, achieving UL94-V0 @ 0.8 mm. Tests covered simple addition of DOPO diamine (DOPOd) to PLA (poly lactic acid), DOPOd reacted into PLA at c. 2:5 ratio and a PLA-PU (polyurethane) polymer...
A PIN FR made wholly from plant-origin materials, in water reaction, was successfully tested in the biodegradable, bio-based polymer PBS. Phytic acid, plants’ natural phosphorus storage molecule, was reacted in aqueous solution with guanosine, a purine nucleoside...
Inclusion of aluminium oxide in polyester with PIN FR ammonium polyphosphate (APP) improved fire performance and mechanical properties. Three different metal oxides (Al2O3, Fe2O3 and Sb2O3) were tested as synergists at 0.5 to 5% in PIN flame retarded unsaturated...
The mineral synergist, zirconium nitride, reduced smoke production by 40% and improved performance of a PIN APP-melamine epoxy intumescent fire coating for steel. The intumescent coating, typical of PIN formulations used to protect steel and other materials in fire,...
Maryland State, USA, has enacted Bill SB0447 banning the sale of mattresses, upholstered furniture or children’s products containing > 0.1% by mass “flame-retardant chemicals”, defined as intended to resist or inhibit fire and containing halogens, carbon plus...
