CellGuard ® 
      for Pulp Bleaching


CellGuard® OP

Concentrated, stabilized reactive magnesium hydroxide aqueous suspension with excellent flow and storage properties. CellGuard OP is a synthetic chemical produced from enriched magnesium brines and dolomitic lime.  It contains lower levels of transition metals as compared to naturally occurring minerals.

CellGuard OP can be used as a cellulose protector in oxygen bleaching systems and as an alkali source in TMP peroxide bleaching and as a partial replacement for caustic soda in EOP bleaching.

CellGuard® 35

CellGuard 35 is a high purity, technical grade of magnesium oxide processed from magnesium-rich brine. This fine white powder has a high reactivity index and a low bulk density. It contains lower levels of transition metals as compared to naturally occurring minerals.

CellGuard can be used as a cellulose protector in oxygen bleaching systems, as an alkali source in mechanical pulp peroxide bleaching and as a partial substitute for caustic soda in EOP and EP bleaching.

CellGuard® MH

CellGuard MH is a fine, white high purity magnesium hydroxide powder produced from magnesium-rich brine. It contains lower levels of transition metals as compared to naturally occurring minerals.

CellGuard can be used as a cellulose protector in oxygen bleaching systems, as an alkali source in mechanical pulp peroxide bleaching and as a partial substitute for caustic soda in EOP and EP bleaching.

CellGuard® NRT

Concentrated, stabilized reactive magnesium hydroxide aqueous suspension with excellent flow and storage properties. CellGuard NRT is a synthetic chemical produced from enriched magnesium brines and dolomitic lime. It contains lower levels of transition metals as compared to naturally occurring minerals.

CellGuard NRT is specifically used for NORPAC’s patented Refiner Bleaching Technology as a replacement for caustic soda and sodium silicate in peroxide bleaching of mechanical pulp. This patented technology provides significant cost savings and benefits over conventional mechanical pulp bleaching processes.

CellGuard®  MH-NRT

CellGuard MH-NRT is a fine, white high purity magnesium hydroxide powder
produced from magnesium-rich brine. It contains lower levels of transition metals as compared to naturally occurring minerals.

CellGuard MH-NRT is specifically used for NORPAC’s patented Refiner Bleaching Technology as a replacement for caustic soda and sodium silicate in peroxide bleaching of mechanical pulp. This patented technology provides significant cost savings and benefits over conventional mechanical pulp bleaching processes.
