D001 Macroporous Strong Acid Cation Exchange Resin
1. Description
It is premium grade,high cross-linked,macroporus strong acid cation exchange resin based on sulfonated polystyrene cross-linked with DVB,the higher DVB content together with its macroporus structure increase resistance to thermal,chemical and physical shocks and enhances overall stability.It is intended for use in water softening,dealkalization,deionirzation and chemical processing application.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.
