Unbleached Softwood Pulp And Unbleached Electrical Grade

Our Prince George mill produces two varieties of unbleached pulp:

  • Unbleached Electrical (UBE) pulp which is produced specially for use in electrical applications where extreme levels of purity and low conductivity are required. Our Unbleached electrical grade pulp meets stringent specifications for extracted conductivity, extracted pH and ash content.
  • Unbleached Kraft (UBK) pulp especially designed for use in application requiring high tensile unbleached fibre and fibre cement products. 

The Prince George Mill produces UBE / UBK pulp from a mixture of softwood species (white spruce and lodgepole pine) indigenous to the north central interior of British Columbia. The highly versatile fibre properties supplied by the regional sawmills make these pulps highly suitable for use in the manufacturing of a wide variety of specialty products, especially those requiring the highest tensile strength. The unbleached pulp production line at Prince George is designed to optimize the fiber properties for ultra-clean electrical applications, fibre cement products and specialty paper applications.
