- High-consistency bleaching (PHC)
High-consistency bleaching (PHC)
The choice of the most cost-effective OptiBright bleaching system depends on the specific brightness target. The optimal system ensures the lowest possible chemical costs.
If, for example, a TMP with brightness of 60% ISO is to be bleached to less than 72% ISO, the recommendation based on chemical cost would be medium-consistency peroxide system or in some cases a dithionite system.
Above 72% ISO, we recommend high-consistency peroxide bleaching (PHC).
