Purolite manufactures Weak Acid cation resins in three different forms: Porous, Macroporous, and Powder. They are primarily used in water softening or dealkalization but also can be used Pharmaceutical applications.
All weak acid cation products have a polyacrylic backbone. The functional carboxylic groups give high chemical efficiency (regeneration) in many applications.
Weakly acidic cation resins are increasingly being used in special applications including treatment of waste water streams in order to reduce environmental pollution.
