PAPEMP performs excellently in high hardness and pH as a new antiscalant and corrosion inhibitor. With high calcium tolerance, PAPEMP scale inhibition ability is also high, particularly for CaCO3, CaPO4, and CaSO4.
It also effectively restrains the Si scale from formation and stabilizes the ions. Such as Mn and Fe, to form chelating compounds.
PAPEMP also has good tolerance to high temperature, high turbidity, high salt concentration, and high chlorine (Cl– and Br–) concentration. Sometimes it is built with polycarboxylic acid.
PAPEMP can be used as a scale and corrosion inhibitor in circulating cool water systems and oilfield refill water systems in high hardness, alkali, and pH value situations.
PAPEMP can be used as a scale inhibitor for reverse osmosis and multistep flash vaporization systems.

PAPEMP production process consists of 4 steps.
Good adaption to different situations enables PAPEMP to be widely used in boilers, cooling water systems, and oilfield reinjection water as an antiscalant and corrosion inhibitor.
For the same reason, PAPEMP is also applied in RO and multistep flash systems. The recommended dosage is 5~100 ml/L. Unlike other organophosphates, there is no optimum dosage for it. Higher the dosage, the better the effect.
Besides, PAPEMP works as a nutrient absorber in agriculture. It can also replace those more expensive color transfer inhibitors (e.g., yellow turnback inhibitors) like EDTA, NTA, and DTPA in textile dyeing.
