Polystrol PS-372
Molecular-type co-polymer paper strength enhancer suitable for paperboard production in acidic to weakly acidic environments.
Polystron PS-372 has been improved from conventional paper strength enhancers to exhibit high water filtration, high aggregation, and high yield effects. Depending on the paper-making system, it can be used alone or as a later-stage formulation of a two-component paper strength enhancer (to improve water filtration and operability).
