Aldex MP Series
C-800H MP Macroporous Strong Acid Resin Hydrogen Form
Aldex C-800H MP is a premium grade, high capacity, strongly acidic macroporous cation resin in the hydrogen form, used in demineralization systems and condensate polishers. Aldex C-800H MP combines high capacity characteristics with increased thermal and chemical stability versus gellular resins. Aldex C-800H MP is more highly cross-linked than our standard non-solvent resins Aldex C-800H and Aldex C-800x10H.

C-800H MP Features
Macroporous Structure
The macroporous structure of Aldex C-800H MP makes 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 that 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 provides greater resistance to bead breakage.
Safety Information
A material safety data sheet is available for Aldex C-800H MP. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-800H MP 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-800H MP should be backwashed for at least 10 minutes at a flow rate sufficient to cause 50% to 75% expansion of the resin bed.
