New Hofmann PAM [H 520 B]

Abstract

Mitsui Chemicals has succeeded in the development of novel type of Hofmann PAM 520 B which shows 1) high paper strength, 2) High drainage, 3) High Retention, especially at relatively high pH condition like pH 5.5pH 7.5 by full use of our special polymerization technology.
It was found that “Core-Branch structure” which can be achieved by a special branching polymerization technology gives good performance to this novel Hofmann PAM 520 B. which is afforded using a unique on -line additive system “Hofmanizer System”
By using Mitsui Chemicals' Hofmann PAM 520 B and Hofmanizer System, a customer can
1) get better unit consumption of paper strength reagent.
2) achieve higher machine speed (10%) without drainage aid.
3) use cheaper pulp like OCC more.
4) Save waste water treatment cost.
