Wood products

Wood products

Materials developed from use of the hard fibrous substance (wood) which makes up the greater part of the trunks and limbs of trees.

Solid wood products include lumber, veneer and plywood, furniture, poles, piling, mine timbers, and posts; and composite wood products such as laminated timbers, insulation board, hard-board, and particle board.

Fiber wood products can be referred to as those which develop initially from the various processes for pulping wood. All are intended to separate the cellulose fibers one from another in relatively pure form to be recombined into layers of pulp, paper sheets, or paperboards. See Paper

Chemical wood products result from the chemical modification or conversion of cellulose, lignin, and extractives. Chief among these products are textile fibers such as rayon, and many cellulose plastics products such as cellophane, nitrocellulose, photographic film, telephone parts, and plastic housewares and toys.
