Abstract: This paper explores TMP produced from chip blends of wood species, two at a time. Black spruce, jack pine, balsam fir, western hemlock, and lodgepole pine were included in the pilot trials. The pulp properties at a given CSF often followed linear or second-order trends between the pure species. The results are used to illustrate how unusual combinations of properties may appear when variations in energy and pulp properties are caused by varying species composition. This represents a challenge for the pulp quality control system.
