Definition:  Pulp made by the thermomechanical process, in which the wood chips are pretreated with a chemical, usually sodium sulfite, either prior to or during presteaming, as an aid to subsequent mechanical processing in refiners.

Context:  Softwood chemithermomechanical pulp (CTMP) is useful in products that can benefit from decreased density. One of the key considerations in the use of softwood pulps is how to achieve a satisfactory formation uniformity. The ratio of length to width (aspect ratio) of softwood fibers is often as high as 100. That means that the fibers have a strong tendency to clump together when suspended in water. In theory one would have to reduce the solids level to less than about 0.01% to give every fiber room to rotate without colliding into an adjacent fiber.
