• Detailed Description:

  Cas No. :26099-09-2 Quantity: 1Metric Tons
  Specs:25kg per barrel
  Payment Method: TT against copy of documents
  Properties: HPMA is brown yellow transparent liquid and is formed by hydrolysis of maleic anhydride. Its molecular weight is about 300-700. The chemical stability and thermal stability of HPMA is high, low toxicity and harmless, and not easy to be hydrolyzed. Under the conditions of high temperature and high PH, the scale inhibition effect of calcium carbonate is better. So it can be mixed use with organic phosphoric acid and zinc salt crude oil.
  Usage: HPMA is widely used as the scale inhibitor in circulation chilled water system, water injection system and low pressure boiler.
