• Detailed Description:

  Cas No. :26677-99-6 Properties:
  MA/AA is a low molecular weight
  polyelectrolyte, a copolymer of
  maleic anhydride and acrylic
  acid. It has good dispersant
  performance against carbonate and
  scale inhibition for phosphate.
  it has good thermal stability,
  can be used under high
  temperature (300℃). MA/AA has
  good compatibility when used
  together with other agents. MA/AA
  is widely used in low-pressure
  boiler, centralized heating,
  centralized air-conditioner and
  circulating cool system. It can
  also be used as chelating
  dispersants in woven and dyeing
  fields.

  3, Application range:
  MA/AA is used in circulating cool
  water system, medium or lower
  pressure boiler and distillation
  system in which high temperature
  is usually encountered. MA/AA can
  be used alone or together with
  other organic phosphates. When
  used together, the dosage of 2-
  10mg/L is preferred. The dosage
  for use as woven & dyeing and
  accessory detergent should be
  determined by experiments.
  Safety Protection:
  Acidity, Avoid contact with eye
  and skin, once contacted, flush
  with water.
  Package and Storage:
  Normally In 25kg or 200kg net
  Plastic Drum, or packed as
  customers’ required. Storage for
  one year in room shady and dry
  place.
