Product Details

Lanlang ® TA201DMB Is a premium grade macroporous type I strong base anion exchange resin with polystyrene matrix, quaternary amine (Trimethylamine) function group and selected particle size. Its macroporous structure makes it can adsorb soluble organic molecules and can resist to osmotic & mechanical shock and oxidation. TA201DMB in chloride form could remove both strong and weak acid radicals such as sulfate, nitrate, arsenate, chromate and silicate to extreme low concentration level. Combining with strong acid cation exchange resin (in hydrogen form), TA201DMB in hydroxide form can be used in all types of demineralization system especially be suited for high flow rate and high temperature polishing. The selected size offers high efficiency during back wash process in regenerable mixed bed applications.
