Abstract


The objectives of this study were to investigate efficacy of a phosphorous-based fire retardant, AG® PI on the fire performance as well as physical and mechanical properties of medium density fibreboard made from rubberwood fibres. The rubberwood fibres were first treated with AG® PI at four different concentrations (10%, 15%, 20% and 25%). (w/v) using hot and cold bath processes. The physical and mechanical properties were investigated using JIS A5906 1983 standard whereas the fire performance was investigated by an in-house method known as reaction to fire test. There was significant interaction (p<0.05) between different of AG® PI concentrations. Generally, fibreboards treated and manufactured with higher concentrations of AG® PI had superior fire performance. The weight loss and burnt area of the fibreboards were found reduced with the increase of AG® PI concentration. The mechanical properties in terms of modulus of rupture (MOR), modulus of elasticity (MOE) were not significantly affected by the AG® PI concentration even though, the values increased with the increase of AG® PI concentration up to 20%. However thickness swelling (TS) and internal bond (IB) properties were minimally affected by the increase of AG® PI concentration. The values of the two parameters were found decrease when the fire retardant concentration increased.
