AA/HPA Copolymer
Acrylic Acid-2-Hydroxypropyl Acylate Copolymer
CAS No.: 55719-33-0
Properties:
T-225 is copolymer of polyacrylic acid and hydroxypropyl acrylate, it has good scale inhibition and dispersion properties to calcium phosphate and calcium carbonate, it has good dispersion properties to ferric oxide sludge, sludge and grease. T-225 can be used at high pH value and has good compatibility with other organophosphines and BTA, T-225 can effectively withhold sediments of zinc salt and calcium phosphate, it has good scale inhibition and dispersion properties under high temperature and alkaline situations.
