Industrial Grade Polymaleic Acid is an effective dispersant and scale inhibitor in cooling water treatment, boiler water treatment, reverse osmosis systems and many other scale control applications such as in textile dyeing, water injection systems in oil fields and sugar mill evaporators. The Acid has low polydispersity and low residual monomer content. The Acid is thermally stable, stable to chlorine and oxidizing biocides at normal use levels. The Industrial Grade Polymaleic Acid ensures scale inhibition of polymeric silica.
