Understanding properties of commercial OSB products

Abstract

Oriented strandboard (OSB) has gained increased market acceptance as a construction material in almost all geographical areas of Canada and United States. With its growing market, more and more research has been focused on the product’s manufacturing and performance. Commercial OSB products in U.S. and Canada are produced from different manufacturers with different process techniques, which result in different physical properties. The common physical and mechanical properties of OSB include MOR/MOE, Internal Bond (IB), Density and Thickness Swell (TS). A comparative study was conducted to investigate mechanical and physical properties among OSB manufacturers. Commercial oriented strandboards from 14 mills were procured either directly from the mill or from the local market (Table 1). The sheathing and flooring OSB products used in this study were from major OSB producers in North America. Species included aspen, pine and other hardwood. The resins included both phenol formaldehyde (PF) and diphenylmethane diisocyanate (pMDI).
