Detailed introduction

Polyamino Polyether Methylene Phosphonic Acid ( PAPEMP )

Alternative name: Polyaminopolyether methylene phosphonic acid                 

Relative molecular mass: approximately 600

CAS No.130668-24-5

Structural formula:

Performance and Applications:

PAPEMP A next-generation water treatment agent, it exhibits excellent chelating and dispersing capabilities, high calcium tolerance, and superior scale‑inhibition performance. This formulation can serve as a scale inhibitor and corrosion inhibitor in recirculating cooling water systems, particularly suitable for waters with high hardness, high alkalinity, and high… pH It is used in circulating cooling water systems and oilfield water treatment. It exhibits excellent scale‑inhibition performance against calcium carbonate, calcium phosphate, and calcium sulfate, while also effectively suppressing the formation of silica scale. Additionally, it provides excellent stabilization of metal ions such as zinc, manganese, and iron.

PAPEMP Scale inhibitors for reverse osmosis systems, scale and corrosion inhibitors for high-salinity, high-turbidity, high-temperature systems such as multi‑stage flash evaporation units (e.g., scale inhibition in high‑temperature, high‑turbidity water systems of coal gasification), textile printing and dyeing auxiliaries, and papermaking additives (yellowing inhibitors); can be used as a substitute. EDTA 、 DTPA 、 NTA Wait.
