Polyamino polyether methylene phosphonate

Polyamino polyether methylene phosphonate (CAS 130668-24-5) is a phosphonate chelating agent for water treatment and industrial processes. Also marketed as PAPEMP or Kemguard 8010.

Where is Polyamino polyether methylene phosphonate used?

• Industrial water treatment: scale deposition control
• Cooling water systems, boilers and reverse osmosis membranes: prevents calcium carbonate, calcium sulfate and barium sulfate
• Threshold inhibition and crystal modification allow effective scale control
• Textile processing: sequesters heavy metal ions that interfere with dyeing uniformity and fabric quality
• Industrial and institutional cleaning: chelant preventing redeposition of hardness minerals
• It stabilizes active ingredients in alkaline detergent systems.

Good to know: Combines sequestration and corrosion inhibition in one molecule, effective at low dosage over a broad pH and temperature range; performs under high hardness and high temperature where conventional phosphonates underperform.

Commercial specifications

• Active concentrations around 20–30%
• Bulk supply in IBC containers and drums
