Abstract
Acacia mangium is the major species planted under the Compensatory Forest Plantation Project. In the Forest Research Institute Malaysia (FRIM), A. mangium has been used, with promising results, for the following panel products, namely particleboard, medium density fibreboard (MDF), cement bonded particleboard (CBP), plywood and decorative panel. Thinnings of 2 to 5-y-old A. mangium can be used for particleboard, MDF and CBP manufacture. Urea particleboard of 2-y-old thinnings satisfies the requirements of Standard Board, as stipulated in the British Standard. MDF from A. mangium, produced with urea or isocyanate resin shows good strength and dimen¬sional properties. CBP produced at a wood-cement ratio of 1 :2.5 with 2 % aluminium sulphate or magnesium chloride passes the Malaysian standard for CBP. The barks of A. mangium have also been used for the extraction of tannin as an adhesive in plywood manufacture. Tannin extract of barks of 4-y-old A. mangium trees shows high reactivity towards formaldehyde, which means that it has good adhesive properties. Plywood manufactured using the bark extracts shows excellent bonding properties with failing loads more than twice the minimum failing load for Boiling Resistant type of adhesive, stipulated in the British Standard.
