Inorganic PIN FRs for cable sheathing

Inorganic PIN FRs for cable sheathing

Three different aluminium and magnesium hydroxides were tested in EVA//LLDME/MA polyolefin cable sheath compound at 60% loading. The PIN FRs tested were synthetic (precipitated) aluminium and magnesium hydroxides and a milled mined mineral magnesium hydroxide (ATH,...
Sulphur phosphorus FR for aircraft seats

Sulphur phosphorus FR for aircraft seats

Several sulfone-bridged phosphorus PIN FR showed effective fire safety in back-coating of polyamide aircraft seat textiles. Four different research S-P PIN FR molecules were synthetised and tested. They were compounded into a polyurethane-based binder at 5%P loading...
P- N synergies for wood fire safety

P- N synergies for wood fire safety

Bio-based PIN FRs, APP and melamine derivative improved fire safety of wood. Bio-based PIN FRs (sodium lignosulfonate and chitosan) were used with ammonium polyphosphate (APP) at 1% – 3% in a melamine-modified urea-formaldehyde resin, applied as a 0.3 mm coating...
Reactive P-N PIN FR for polyester

Reactive P-N PIN FR for polyester

A 1-vinylimidazole phosphite salt, reacted into unsaturated polyester resin @ 15% achieved UL 94 V-0 (3.2 mm), and over 60% reductions in peak heat release rate and smoke production. 1-vinylimidazole was reacted with phosphorus acid at a 2:1 ratio in ethanol to...
Optimisation of bio-based PIN intumescent

Optimisation of bio-based PIN intumescent

Heat barrier effect of tannic acid – ammonium polyphosphate (APP) intumescent increases with porosity and char. These PIN FR compounds were tested in DGEBA resin with a polyamine hardner. Heat transfer was tested using heat flow meter tests with the intumescent...
