PIN FRs showed effective in particle board

An ATH – APP based PIN FR system reduced heat loss and smoke emission from wood – polyester particleboard. The particleboard was produced by compression molding of sawdust with polyester resin, after treating the sawdust with sodium hydroxide to improve compatibility. A PIN FR system consisting of ATH (aluminium trihydroxide), APP (ammonium polyphosphate), gum Arabic powder and carbon black (1:1.5:3:3) was tested at 0 – 18% loading in horizontal burn tests of 100 x 000 x 10 mm samples. At 18% loading the PIN FR reduced heat release (FIGRA) from 388 to 37 kW/s (no FR), and smoke release from 39 to 3 m2/s2. The Construction Products Regulation classification was thus improved from D-S2 to B-S1. The authors conclude that PIN FR treated particleboard contributes very little to fire.
