Abstract
Waferboards were made from 5 and 9 year old hybrid poplars, using laboratory prepared wafers. The binder was a powder consisting of a mixture of phenol-formaldehyde (PF) resin and comminuted hybrid poplar bark in equal weights. Only 1.25% PF resin was used based on weight of dry wood. These boards had bending strength and internal bond strength much in excess of the minimum required by Canadian Standards. Another binder was used composed of white spruce tannin, hybrid poplar bark and PF. This amount of PF based on dry wood was 0.5%. this mixture also gave strong boards, both dry and wet, at densities of 42 pounds per cubic foot.
