Unbleached Softwood Pulp
These pulps are only produced at one of our pulp mills:
Interior BC - Prince George mill
Unbleached interior softwood kraft pulps
Canfor produces unbleached pulps at its Prince George
mill only. This mill is registered under the ISO 9001
(quality) and ISO 14001 (environmental) management standards.
The mill produces 2 varieties of unbleached pulp. One
is especially designed for use in application requiring
high tensile unbleached fibre, this is our UBK pulp.
The other grade is our UBE pulp which is produced especially
for use in electrical applications where extreme levels
of purity and low conductivity are required.
Our fibre supply is a blend of white spruce (picea
glauca), lodgepole pine (pinus contorta) and alpine
fir (abies lasiocarpa). The majority of this supply
is the residual material from local sawmills. Due to
the climatic conditions in the region - long cold winters
and relatively short dry summers - these species naturally
develop long, slender and thin-walled fibres. These
fibre properties result in pulp that not only has excellent
tensile strength properties, but also offers superior
wet web reinforcement and sheet dimensional stability.
The mill has highly sophisticated distributed control
systems, a continuous digester, and modern bleaching
and screening systems. The pulp produced is clean, free
of dirt and shives.
