D111 This is a kind of cation exchange resin which has carboxylic acid groups [-COOH] in the macroporos acrylic acid-divinylbenzene copolymer. It works with large exchange capacity, speedy exchange ability, small volumn change, good physical strength and chemical stability, excellent capabilities of contamination and oxidation resistance etc.

This product is a kind of anion exchange resin which has polyamine groups in the methyl acrylate-divinylbenzene copolymer, with macroporous structure. This resin has good properties, such as large exchange capacity, small volumn change, strong physical strength, good chemical stability, excellent resistence to contamination and oxidation, speedy exchange capability etc.

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.
