Cooling water systems: HPMA is added to prevent the formation of scale deposits
on heat transfer surfaces and to inhibit corrosion of metal components in
cooling water systems.

Boiler water treatment: HPMA helps to control scale formation and corrosion in
boiler systems, improving heat transfer efficiency and extending equipment
lifespan.

Industrial water systems: HPMA is used in industrial processes involving water,
such as pulp and paper manufacturing, textile processing, and oilfield
operations, to prevent scale formation and protect equipment.

Reverse osmosis (RO) systems: HPMA is added to RO membranes to inhibit scaling
caused by minerals and salts, ensuring efficient operation of the RO system.

Detergent formulations: HPMA is used as a builder and chelating agent in
detergent formulations, enhancing the cleaning performance by preventing the
precipitation of hardness ions.
