This product is a macroporous structure of styrene-divinylbenzene and tertiary amine [-N(CH3)2] ion exchange resin. It is weakly alkaline and can be effectively used in acidic near-neutral media. Removal of organic and inorganic acids and silicates, adsorption of molecular-sized impurities, used in non-aqueous solutions. The resin has high regeneration efficiency, large exchange capacity, strong anti-pollution ability and good mechanical strength. This product is equivalent to Amberlite IR-93/94, Purolite A-100.
