PAPE 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, as well as the sediment dispersing ability.  It has good inhibition effect for barium and strontium scales. PAPE has good scale inhibition effect for calcium carbonate and calcium sulfate in the water system and cathodic protection effect for steel. PAPE can mix well with polycarboxylic acid, organophoronic acid, phosphate and zinc salt.

PAPE can be used as scale inhibitor for oilfield (recommended as alternatives of Nalco Visco 953) and industrial cool water system.
