This research was to determine the adhesive content effect on the physical and mechanical properties of particleboard from Kapok Husk (Cebiapentandra L.Gaertn) during hotpressing with press temperature (150 °C) at 15 minutes. The size of board was (15.2 x 15.2) cm2 and targeted density 1.0 gcm-3 was prepared by using 10, 15, 20, 25 and 30% ureaformaldehyde (UF) respectively over all based on oven-dry particles. The properties of particleboards were determined by British Standard (BS) and Indian Standard (IS) Methods. From the observation of properties obtained, it should be like that the highest modulus of rupture (MOR), impact strength, the lower water absorption (WA) and swelling thickness (ST) which were 7256 psi (508 kgcm-2), 36.20 kjm-2, 30.32% and 22.22% respectively. The results obtained fulfilled to FAO (2013) standards. The particleboard (PB 5) by using (30%) UF was the best condition for resulting of properties. The control of adhesive concentration is the one of the most important factors for the production of particleboard. Kapok husk particleboard may be a sustainable, cheap and durable building and packing materials and wall partitions.
