Pulp & Paper

Evonik is a leading supplier of persulfates as repulping aid for paper products containing wet strength resin. Historically, sodium hypochlorite was used to break down wet strength paper products; producing free chlorine which could result in corrosion and organic halide by-products.

Persulfate salts are environmentally friendly, non-halogenated compounds which can be used to oxidize the wet strength resin for reprocessing of broke, or off-spec paper to be recycled.
