We are in the process of producing fiberboards from various types of acetylated lignocellulosic fibers. Most of our research has been on pine or aspen particleboards or flakeboards, so the data presented here on dimensional stability and biological resistance come mainly from these types of boards. 

Specifications, Standards, Quality Control, and Health and Safety Factors. Formerly, there was an Insulation Board Institute representing the insulation board industry, but the decline in the market and number of producers has led to its demise. Currendy (ca 1997), the industry is represented by the American Hardboard Association (AHA). Specifications and standards are found in American National Standards Institute (ANSI) standard for CellulosicFiberboard (7). The standard includes descriptions of the various types and classes of fiberboard, as well as requirements for physical and dimensional stability properties. Quality control tests are limited to a few basic strength and stability tests, including bending strength, bond strength, and moisture resistance. 

The book opens with a paper on the structure and composition of wood to define the material under discussion and then considers molds, permeability, wood preservation, thermal deterioration and fire retard-ance, dimensional stability, adhesion, reconstituted wood boards such as fiberboard and particleboard, plywood, laminated beams, wood finishes, wood-polymer composites, and wood softening and forming. A final paper treats the common theme of wastewater management. Only one of the papers presented at the meeting is not included in this volume, and its subject of conventional wood preservation methods is adequately treated in detail elsewhere (e.g., Nicholas, D. D., Ed Wood Deterioration and Its Prevention by Preservative Treatments, 2 vols., Syracuse University Press, 1973). 

More recently, vaporous FA treatment has been applied to the improvement of dimensional stability of medium-density fiberboard (MDF) (36). Among... 

Since the bonding strength of benzylated wood surfaces was similar to that achieved using commercial hot-melt adhesives, the development of self-bonded wood materials using surface benzylated particles was possible [32]. Suzuki and Iwakiri [33] reported that self-bonded fiberboard produced from benzylated asplund-processed fibers had high thermoplasticity, dimensional stability, and water resistance. Morita and Sakata also produced hot-melt cyanoethylated fiberboards, but they showed poor water resistance [34]. Both benzylated and cyanoethylated fiberboards lacked many of the inherent good properties of solid wood because they did not retain the cellular construction of wood.
