Polyamino Polyether Methylene Phosphonic Acid, PAPEMP

POLYAMINO POLYETHER METHYLENE PHOSPHONIC ACID (PAPEMP)

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

Short Identity Section

Detailed Identification

Description:
PAPEMP is a high-performance water treatment chemical that provides superior scale and corrosion control, especially under high hardness, high alkalinity, and high pH conditions. Its high chelation and dispersion capacity allows it to work effectively in challenging industrial water systems. PAPEMP effectively inhibits the formation of calcium carbonate, calcium sulfate, and calcium phosphate scales. It also demonstrates high performance in controlling silica-based deposits and stabilizes metal ions such as zinc, manganese, and iron. According to ECHA, it is registered with EC number 682-650-0.

2. PHYSICAL AND CHEMICAL PROPERTIES

Note: Values are typical and may vary by source and production batch. The density of the 40% solution is typically 1.15–1.25 g/cm³.

3. SOLUBILITY PROFILE

Note: PAPEMP is soluble in water. Solubility data for organic solvents are not specified in the sources.

4. CHEMICAL PROPERTIES AND REACTIONS

Incompatibilities

• Strong oxidizing agents

20. SUMMARY AND CRITICAL WARNINGS

SUMMARY

PAPEMP (Polyamino Polyether Methylene Phosphonic Acid) is a high-performance water treatment chemical that provides superior scale and corrosion control, especially under high hardness, high alkalinity, and high pH conditions. Its high chelation and dispersion capacity allows it to work effectively in challenging industrial water systems. PAPEMP effectively inhibits the formation of calcium carbonate, calcium sulfate, and calcium phosphate scales. It also demonstrates high performance in controlling silica-based deposits and stabilizes metal ions such as zinc, manganese, and iron.

It appears as a clear colorless to pale yellow aqueous solution. Its active content is ≥40.0%, density is ≥1.15 g/cm³ (20°C), pH is ≤2.0 (1% solution), and molecular weight is approximately 600 g/mol. It is soluble in water.

It is used in open and closed circuit cooling water systems, industrial circulating water systems, oilfield injection and reinjection water systems, high hardness operating water, reverse osmosis (RO) systems, NF and UF pre-treatment applications, multi-stage flash (MSF) evaporation systems, coal gasification plants, and the textile industry.
