Purolite manufactures two types of weak base anion ion exchange resins: weak base anion gel and weak base anion macroporous. Our weak base anion gel products have an acrylic backbone while our weak base anion macroporous products have either an acrylic or styrenic backbone.
Weak base anions are more chemically stable than strong base anions and are used for the removal of mineral acids, organic acids and other organic materials. They are highly resistant to organic fouling.
