Dry process fiberboard

Description

A process for forming hardboards that was developed in the early 1950s. In the dry process, the fibers were broken apart with steam and water baths. However, once, the fibers are separated they are dried first, then pressed into a rigid board using extremely high pressures. This technique produces a board that is smooth on both sides and reduces waste liquors significantly. However, the dry fibers lack natural cohesion, so synthetic adhesives are added to improve strength. Dry process fiberboard is often made from recycled paper with adhesives, ink and other residues from the original products (Hatchfield 2002).
