the effects of fire retardants on the properties of particle boards made from cottonseed hulls were studied. the boards were treated with (1) 70 borax $plus$ 30 boric acid (fr(1)); (2) 60 borax $plus$ 25 boric acid $plus$ 15 ammonium dihydrogen orthophosphate (fr(2)) and were evaluated for duration of flaming, after-glow, charred area, charred length and per cent loss in weight, along with physico-mechanical properties. fire retardant properties, water resistance and per cent thickness swelling improved, and bending strength decreased, with increase in concentration of fire retardants. treatment (2) was found to be the better fire retardant since it served the dual purposes of flame and glow retardation (author abstract) 8 refs
