Weak acid series >>001×7(732)Strongly acidic styrene-based cation exchange resin

001×7(732)Strongly acidic styrene-based cation exchange resin

I. Execution Standards:GB13659-92

This product is made from styrene=Sulfonic acid groups are attached to the polymer matrix of the ethylene-benzene copolymer cross-linked structure(-SO3H)The ion exchange resin has an acidity comparable to that of inorganic acids such as sulfuric acid and hydrochloric acid. It demonstrates ion exchange functionality in alkaline, neutral, and even acidic media. This product features high exchange capacity, fast exchange speed and good mechanical strength.

The original grade of this product732#Equivalent to the United States:Amberlite IR-120,Dowex-50; GermanyLewatit-100;
