ALDEX MP Series
C-800MP Water Softening Resin Sodium Form
Aldex C-800MP is a premium grade, high capacity, strongly acidic macroporous cation resin in the sodium form for use in water softening. Combines high capacity characteristics with the increased resistance to oxidation required for waters having high temperature, and/or high amounts of oxidizing agents such as chlorine, ozone, and hydrogen peroxide and/or high amounts of iron. Aldex C-800MP is more highly crosslinked than our standard gel-type cation resin, Aldex C-800.

C-800MP Features
Macroporous Structure
The macroporous structure of Aldex C-800MP make it possible to incorporate a higher level of divinylbenzene into the copolymer matrix than is possible with standard gel type resins. This results in a resin which has greater stability when exposed to oxidizing conditions such as high temperatures, iron and the presence of oxidizing agents.
High Physical Stability
The macroporous structure with high divinylbenzene content and uniform particle size provide greater resistance to bead breakage.
Low Pressure Drop
The uniform particle size of 98%+ in the 16-50 mesh size range gives Aldex C-800MP a lower pressure drop while maintaining the superior kinetics of standard mesh resin.
Safety Information
A material safety data sheet is available for Aldex C-800MP. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-800MP is not a hazardous product and is not WHMIS controlled.
Caution: Acidic and basic regenerant solutions are corrosive and should be handled in a manner that will prevent eye and skin contact. Before using strong oxidizing agents in contact with ion exchange resin, consult sources knowledgeable in the handling of these materials.
Pressure Drop
Backwash Characteristics
Aldex C-800MP should be backwashed for at least 10 minutes at a flow rate sufficient to cause 50% to 75% expansion of the resin bed.
