Abstract
Particleboards (PBs) were made from Pinus densiflora thinning particle with urea-formaldehyde (UF) resin added casein and soybean as extender. The performance test results of the PB made showed that Pinus densiflora thinning log was suitable raw material for PB. As the extender addition in the UF resin was increased, the mechanical performance of the PB, bonded with the extended UF resin, were significantly decreased. However, casein and soybean can be used up to 15% and 20% of the UF resin solids respectively.
