Effects of the resin content and particle size on the properties of particleboard made of Neolamarckia and Leucaena particles

Abstract

A shortage in the rubberwood supply is becoming a reality in Malaysia. To find alternative raw materials for Malaysian wood-based industries, fast-growing species have been identified and need to be analyzed in particleboard manufacturing. This study evaluated the properties of particleboard made with a 50:50 ratio of Neolamarckia cadamba and Leucaena leucocephala with melamine urea formaldehyde as the resin at different contents (10%, 12%, and 14%) and particle sizes (1.0 mm, 2.0 mm, and unscreened particles). The particleboards were tested according to EN 312 (2003). The results showed that the particleboard mechanical properties were significantly improved with increase of the resin content and particle size. The thickness swelling value dropped as resin content was increased, showing better stability of the board.
