201W is a sort of anion exchange resin that has quaternary ammonium group [-N(CH₃)₃OH] in the cinnamene styrene and diethenoid benzene copolymer. It is used specially to separate and purify of the tungsten and molybdenum in the hydro metallurgy, with the characteristics such as high exchange capacity and good separation effect and so on.

This is a kind of anion exchange resin which has tertiary amine groups in styrene-divinylbenzene copolymer. It can remove effectively organic coloring matters, inorganic acids and silicates from acidic and nearly neutral medium, with its weak alkalinity. It also can adsorb the big-sized impurities and be used in non-aqueous solution. This resin has good properties, such as highly-efficient regeneration capability, large exchange capacity, strong contamination resistance, excellent physical strength etc.

D354 is a sort of anion exchange resin that has tertiary amine group [-N(CH₃)₂] in the cinnamene styrene and diethenoid benzene copolymer with macroporous structure. It is used mainly to absorb and recover aurum in the solution and waste water that contains aurum, absorb and recover hexavalent chrome in the solution and waste water that contains chrome, absorb and recover hexavalent hydrargyrum in the solution and waste water which contains hydrargyrum.

D380Wis a sort of anion exchange resin that has tertiary amine group [-N(CH3)2] in the cross linking acrylic acid copolymer with macroporous structure. It is used specially to separate and purify of the tungsten and molybdenum in the hydro metallurgy, with the characteristics such as high exchange capacity and good separation effect and high mechanical intensity and so on.

D280U is a sort of anion exchange resin that has quaternary ammonium group [-N(CH3)3OH] in the cinnamene styrene and diethenoid benzene copolymer with macroporous structure. It is used mainly to absorb and enrich and purify uranium in the uranium mine and its waste water, enrich and separate thorium and plutonium and uranium in the nuclear industry, treat and recover vanadium in the waste water produced in ammonia synthesizing, separate and remove zinc in the nickel electrolyte.

D382 is a sort of anion exchange resin that has tertiary amine group [-N(CH₃)₂] in the cinnamene styrene and diethenoid benzene copolymer with macroporous structure. It is used mainly to enrich and extract uranium in the uranium mine solution, separate and remove plumbum in the nickel and cobalt electrolyte, with uniform grain size distribution.
