Advantages
This product is a type of ion exchange resin where the polymer matrix of styrene-divinylbenzene copolymer crosslinking structure has a quaternary ammonium group [-N(CH3)3]. The alkality of this product is equivalent to that of normal quaternary ammonium alkali. It also presents ion exchange function in acidic,neutral,even alkaline medium. The product possesses good mechanical strength and high heat resistibility.
