Potassium Monopersulfate Compound for Paper Repulping

Potassium Monopersulfate Compound for Paper Repulping

Short Description:

Potassium monopersulfate compound is a powerful repulping aid, helping to increase paper-plant efficiency and protecting paper plant workers with an environmental-friendly technology.

In order to efficiently disperse these pulp fibers during repulping it is necessary to remove the water-resistant WSR from the paper product. This can be notoriously difficult. PMPS repulping aid can help.

Potassium monopersulfate compound has been used in pulp and paper mills as a WSR repulping aid for over 30 years. It provides a combination of efficient repulping performance and chlorine-free processing in one product, oxidizing PAE without damaging pulp fibers.
The favorable environmental and safety profiles make PMPS a sustainable and effective choice for repulping wet strength paper grades. In fact,PMPS is the first raw material verified by Green Seal for removal of WSRs in paper repulping.

Related purposes

Currently, potassium monopersulfate compound is usually used in paper repulping, the products includes tissue, towel, napkin, coffee filter, wet strength carrier board,  secondary fiber treatment.
Due to the versatile nature of PMPS chemistry, it is possible to optimize repulping conditions for more challenging products. For example, liquid container boards, carrier boards, milk cartons, labels, corrugated liner board, unbleached paper or high PAE-content products.


1) It can effectively solve the problems of paper damage and waste paper reuse of wet strength paper using PAE.
2) It can effectively reduce beating time and save energy.
3) After use, it can be directly used in papermaking without washing, and does not affect the effect of paper sizing or other additives.
