Polyhydric alcohol phosphate ester (PAPE)

Structural Formula:

Polyhydric alcohol phosphate ester (PAPE) Structural Formula

Properties :

Polyhydric alcohol phosphate ester is a new kind of water treatment chemicals. It has good scale and corrosion inhibition ability. Because more than one ployethylene glycol group is introduced into the molecular, the scale and corrosion inhibition for calcium scale is improved. It has good inhibition effect for barium and strontium scales. Polyhydric alcohol phosphate ester has good scale inhibition effect for calcium carbonate and calcium sulfate, it can mix well with polycarboxylic acid, organophoronic acid, phosphate and zinc salt.

Polyhydric alcohol phosphate ester can be used as scale inhibitor for oilfield (recommended as alternatives of Nalco visco 953) and industrial cooling water system.
