Macroporous Strong Basic Styrene-based Anion Exchange Resin


D201 is a premium-grade macroporous anion exchange resin. The inner structure of its macropore is highly uniform and firm for its advanced synthesis technology, which enables its excellent resistance to mechanical and osmotic shock and its strong capability to bond to other substances. It has been ranked as the top-resin product to be applied to multiple leading industries such as metallurgy, chemical engineering, electric power, electronics, semiconductors, food, cosmetics, pharmaceuticals, etc.
