C-800H MP UPS Features

Macroporous Structure

The macroporous structure of Aldex C-800H MP UPS 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 presences of oxidizing agents.

High Physical Stability

The macroporous structure with high divinylbenzene content and uniform particle size provides greater resistance to bead breakage.

Low Pressure Drop

The uniform particle size of 95%+ in the 20-40 mesh size range gives Aldex C-800H MP UPS 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-800H MP UPS. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-800H MP UPS 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.

Backwash Characteristics

Aldex C-800H MP UPS should be backwashed for at least 10 minutes at a flow rate sufficient to cause 50% to 75% expansion of the resin bed.
