ATH from secondary materials

ATH from secondary materials

Aluminium trihydroxide was produced from anodisation residues and demonstrated as a PIN flame retardant in polyethylene. Anodisation of aluminium items uses an acid bath to generate a corrosion resistant surface. Waste from a Brazil aluminium plant was a humid solid....
Bismuth – phosphorus nitrogen PIN synergy

Bismuth – phosphorus nitrogen PIN synergy

A molecule combining bismuth with melamine phosphate shows synergistic fire and smoke reduction in epoxy. Phosphoric acid was reacted with pentaerythritol, then with melamine, then with bismuth oxide (Bi2O3, 10% w/w) and additional melamine. The resulting PPMS-Bi [1],...
Research into reactive PIN FRs

Research into reactive PIN FRs

Looking for solvent-free, low toxicity, reactive phosphorus PIN flame retardancy for polyamide (PA6). A reaction-extrusion process was tested to generate phosphorus-containing modified polyamide, containing also phosphorus oligomers. This was then melt-spun to textile...
Nickel ammonia phosphate

Nickel ammonia phosphate

Research shows that the PIN chemical NiNH4PO4.H2O can reduce flammability and smoke emission from epoxy resin. Three different nano-morphologies of nickel ammonia phosphate (NiAP) were synthesised in a one-step precipitation reaction, then tested in 0 – 7 % loading in...
