Specification :

D001 Macroporous Strong Acid Cation Exchange Resin
1. Description
D001 is a premium grade , high cross-linked, macroporous strong acid cation exchange resin based on sulfonated polystyrene cross-linked with DVB, The higher DVB content together with its macroporous structure gives D001 increase resistance to thermal, chemical and physical shocks and enhances overall stability.D001 is intended for use in water softening, dealkalization, deionization and chemical processing applications. It is ideally suited for use in severe operating conditions, especially where standard grade resin are known to fail due to thermal, osmotic or oxidative attack.
