WDX-4 Absorption Resin

This product is a type of macroporous adsorptive resin made by filling appropriate pore forming agent in St-DVB and then forming macroporous and mesh high molecular polymer through high temperature polymerization and finally by adopting special method for treatment after pore forming agent being extracted,which possesses broad adsorption and abruption effect as it s provided with macroporous and mesh structure and special pore size distribution.This product is mainly applicable for extracting various macromolecular non-polar substances from polar solutions i.e.extraction,abruption and concentration of organic pigment,phenols &its homologous compound and condensed nucleus organic compound &inorganic compound,etc.from biological zymotic fluid and discharge water.It also performs well for purification of VB12 in Pharmaceutical Industry.It is rather steady in normal usage and storage conditions,insoluble in water, common acid,alkali and conventional organic solvent.This product possesses the following advantages:large specific surface area,medium polarity;good mechanical strength,long service life;regular and reasonable pore size distribution;strong resistance to organic pollutants;good performance in regeneration,high regeneration rate.This product is equal to foreign products-XAD series.
