Up-dated Config file. Wood pulp is a dry fibrous material prepared by chemically or mechanically separating the fibers which make up wood. This is the fluffy type of pulp, shipped in covered hoppers.
This is the raw material that is used to make paper, paperboard, and cellulose products such as insulation. It's a fibrous material made of trees that has been mechanically ground or chemically processed to separate the wood fibers and give them an even consistency; it is then bleached (sometimes) before it is shaped into the desired product and dried. The source of wood pulp is either virgin wood (softwood trees are most often used for paper) or recycled paper and paperboard.
