Advantages
This product is a type of ion exchange resin where the copolymer matrix of styrene-divinylbenzene copolymer crosslinking structure has a sulfonic group(-SO3H). Acidity of the product is equivalent to that of inorganic acid such as sulfuric acid and hydrochloric acid. This type of product presents ion exchange and ion extraction functions in alkaline,neutral,even acidic medium. This product also possesses characteristics of large exchange capacity,fast exchange speed and good mechanical strength.
