001×4 is a cation exchange resin with sulfonic group (-SO₃H) on styrene 4% divinyl-benzene copolymer.It is suitable for use in water or non-aqueous media, especially for the extraction of many antibiotics and separation and extraction of amino acids.It has uniform particle size distribution and high exchange capacity.

This is a kind of weakly alkaline anion exchange resin with primary amine, secondary amine, tertiary amine and quaternary amine groups [-NH₂、=NH、=N、=N-] in the epoxy chloropropane-polyethylene polyamine copolymer. It can be used as ion exchanger in acidic,neutral and alkaline mediums, with large exchange capacity and speedy exchange ability.

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 special poroid structureand good properties, such as large exchange capacity, strong physical strength, good chemical stability, excellent resistence to contamination and oxidation, speedy exchange capability, regenerating easily etc.

This is a kingd of cation exchange resin which has carboxylic acid groups [-COOH] in the phenolic aldehyde copolymer.　　

C108 is cation exchange resin with sulfonic group (-SO₃H) on styrene-divinyl-benzene copolymer，It is suitable for use in water or non-aqueous media, especially for refining and refining lysine, sorbitol, vitamin C and mannitol.With uniform particle size distribution and strong wear resistance, resistance to permeation pressure, oxidation resistance, uniform particles and high exchange rate of resin, the exchange and adsorption capacity of the medium can be improved.

001×12 is cation exchange resin with sulfonic group (-SO₃H) on styrene 12% divinyl-benzene copolymer.It is suitable for use in water or non-aqueous media, especially for the removal of cationic impurities in the production of antibiotics such as gentamycin, streptomycin and oxytetracycline.It has uniform particle size distribution, high volume exchange capacity, wear resistance, permeability resistance and oxidation resistance.
