Product details


001×7(732)Gel Type Strong Acid Cation Exchange Resin



1. Executive standard: GB/T 13659-2008 DL/T519-2004



This product is an ion exchange resin with a sulfonic acid group (-SO3H) on a polymer matrix of a styrene-divinylbenzene copolymerized crosslinked structure. Its acidity is equivalent to inorganic acids such as sulfuric acid and hydrochloric acid. It is alkaline and neutral. Even the acid medium shows the ion exchange function. This product has the characteristics of high exchange capacity, fast exchange speed and good mechanical strength.



The original grade of this product 732#,Equivalent to the US:Amberlite IR-120,Dowex-50;Germany:Lewatit-100;
