Abstract

This paper discusses the results of water absorption, thickness swelling, and internal bond tests of commercial North American wood strand and fiber composites treated using a vapor boron treatment process. For oriented strandboard (OSB), high boron loadings led to lower internal bond strength and lower thickness swelling. Water absorption results were variable but no deleterious effect of treatment was noted. For medium density fiberboard (MDF), the highest loadings led to reduced internal bond strength. Thickness swelling decreased with increasing boron level, but not significantly. As with OSB, water absorption results varied.
