Briteframe PESA is a phosphor-free, nitrogen-free, biodegradable multivariate polymer; a scale and corrosion inhibitor and dispersant comparable to conventional polyacrylates and in function comparable to phosphonates. It disperses calcium carbonate, calcium sulphate, calcium fluioride and silica scale with effects better than that of ordinary organophosphines.
Briteframe PESA can be used in high alkaline, high water hardness, chlorine, chlorite and other water treatment agents, as well as high concentration index.
The applications are: cooling and boiler water systems, reverse osmosis, oilfield water, desalination plants, nutrient absorber in agriculture.
Average Molecular weight: 1500
Briteframe PESA is readily biodegradable under OECD301b; over 60% within 28 days (ISO-9439)
