Description

B27N covers the manufacture of wood-based composite materials and products through dry processing methods, including particleboards, fiberboards, and similar engineered wood products made from wood particles, fibers, or lignocellulosic materials, with or without added organic binders. The processes encompassed include particle or fiber preparation, blending with adhesives, mat formation, pressing, and finishing of these dry-processed composites. This classification excludes wet or semi-wet processes (covered under B27M) and focuses specifically on industrial-scale production of sheet materials and related articles used in furniture, construction, and packaging applications.
