HPMA has excellent scale inhibition and high temperature resistance, and is mostly used in circulating cooling water, crude oil dewatering treatment and furnace treatment of low-pressure boilers, with good inhibition of scale generation and stripping the role of old scale.


PBTCA is the most widely used in the compounding of high-efficiency scale and corrosion inhibitor, and it is one of the best performance products, and also an excellent stabilizer for zinc salt. 

It is mainly used in circulating cooling water system and oilfield water injection system for corrosion and scale inhibition, especially suitable for compounding with zinc salt and copolymer.


ATMP has good chelating, low limit inhibition and lattice distortion effects. It can prevent the formation of scale in water, especially calcium carbonate scale.

It is mainly used as scale prevention and scale inhibition dispersant for open industrial circulating water system, water pipeline and boiler.


HEDP is a kind of organic phosphorus acid scale and corrosion inhibitor, can form stable complexes with iron, copper, zinc and other metal ions, can dissolve the oxides on the metal surface. HEDP can still play a good role in corrosion and scale inhibition at 250℃, still very stable at high pH, not easy to hydrolyze, not easy to decompose under general light and heat conditions.

It is mainly used as industrial circulating cooling water, oil field injection and boiler water treatment.
