Abstract
The disclosure relates to foamed binders for wood strand products and methods and systems for producing wood strand products using foamed binders. In some embodiments, the disclosure includes a method for producing a wood strand product from cellulosic particles, the method comprising the steps of foaming a phenol formaldehyde binder to produce a foam, tumbling the cellulosic particles in a rotary blender, applying the foam to the cellulosic particles in the rotary blender, blending the cellulosic particles and the foam so that the foam covers the cellulosic particles, and consolidating the cellulosic particles under heat and pressure.
