Peracetic Acid

Our distilled peracetic acid (dPAA) is used as a delignifying and brightening agent in the production of environmentally friendly TCF and ECF pulps. dPAA is an excellent product for post-bleaching of pulps.

High and even pulp brightness of the pulp, with good stability, can be achieved in post-bleaching using dPAA in storage towers of bleached pulp. Post-bleaching is an outstanding tool for producing a fiber quality that meets downstream needs. Mills having problems with brightness variation, reaching brightness target, post-bleach yellowing, and cleanliness of pulp or paper have successfully applied it. Additionally, a reduction in consumption of optical brighteners and biocides can be obtained with improved retention of wet end chemicals. The overall costs in the pulp and papermaking process will be reduced with the help of dPAA post-bleaching.

Kemira is the biggest producer of distilled peracetic acid in the world.
