PAPEMP is a new‑generation water treatment agent with high chelating‑dispersing capacity, excellent calcium tolerance and outstanding scale inhibition performance. It can be used as scale and corrosion inhibitor for circulating cooling water systems. It is especially suitable for circulating cooling water systems and oilfield water treatment under high‑hardness, high‑alkalinity and high‑pH conditions. It exhibits superior scale inhibition against calcium carbonate, calcium phosphate and calcium sulfate, and can effectively prevent silica scale formation. Meanwhile, it features good stabilizing effect on metal ions such as zinc, manganese and iron.
Alias: Polyamino‑polyether methylenephosphonic acid
Relative Molecular Mass: approx. 600

Meanwhile, it features good stabilizing effect on metal ions such as zinc, manganese and iron.
PAPEMP is applied as membrane scale inhibitor for reverse osmosis systems, scale‑corrosion inhibitor for multi‑effect distillation and other high‑salinity, high‑turbidity and high‑temperature systems (e.g. high‑temperature & high‑salinity water systems in coal gasification). It can also be used as textile printing & dyeing auxiliary and papermaking additive, serving as substitute for EDTA, DTPA, NTA, etc.
| Item | GB/T27812‑2011 | ‑‑‑‑ |
|---|---|---|
| Appearance | Light yellow or yellow transparent liquid | Light yellow or yellow transparent liquid |
| Active Component (as PAPEMP) % | ≥36.0 | ≥40.0 |
| Phosphorous Acid (as PO₃³⁻) % | ≤2.5 | ≤2.5 |
| Phosphoric Acid (as PO₄³⁻) % | ≤1.0 | ≤1.0 |
| Density (20℃) g/cm³ | ≥1.15 | ≥1.15 |
| pH (1% aqueous solution) | ≤2.0 | ≤2.0 |
| Iron (as Fe²⁺) content, mg/L | ≤35 | ≤35 |
Normal dosage ranges from 5‑100 mg/L. Different from other agents, higher dosage brings better performance for PAPEMP. It can also be compounded with polycarboxylic acids. High dosing dosage enables operation at high concentration multiple.
Packed in plastic drums, 25 KG or 200 KG per drum. Store indoors in cool place. Shelf life: 10 months.
PAPEMP is acidic liquid. Take labor‑protection measures during operation. Avoid contact with skin and eyes. Rinse immediately with plenty of clean water upon contact.
