Re: TCF Pulp Market & Pulp strength
As per information from UPM-Kymmene's (world's second largest (by volume)
paper company) director of R&D, Dr. Kari Ebeling, UPM-Kymmene has found
that there is a four percent increase in hardwood consumption during
production of bleached hardwood kraft pulp with TCF method in comparison to
the corresponding ECF production. The company also found that the tear
strength of TCF bleached softwood pulp has been about 5 to 10 percent
weaker than that of the ECF bleached softwood pulps. This means that the
mill needs to increase the amount of softwood pulp in order to provide the
same reinforcement capability into the magazine papers than in the case of
the corresponding ECF bleached softwood pulps.
In regards to the comments about a market for TCF pulp, it only has
occupied six percent of the world bleach chemical pulp market for the past
three years. ECF's market continues to grow this year surpassing all other
bleaching processes commanding 50 percent of the world market.
If you have any questions about ECF bleaching processes or market trends,
