ALDEX Mixed Bed Series
MB-1 Mixed Bed Resin
Aldex MB-1 is a highly regenerated mixed bed of a Type 1 strong base, gel anion exchange resin and a strong acid sulfonated polystyrene cation exchange resin, designed to provide ultra-high purity water. The special blend of Type 1 anion exchange resins with nuclear grade cation exchange resins ensures high resistance, low TOC extractables and excellent regenerable capacities for inorganic versus organic ions. Aldex MB-1 is provided in a 60:40 anion to cation ration (by volume).

MB-1 Features
Very Low Metal Content
Special manufacturing conditions ensure very low metal content.
Elemental analysis, dry basis
| Iron (Fe) | <100 ppm |
| Copper (Cu) | <50 ppm |
| Lead (Pb) | <50 ppm |
Very Low TOC
Nonsolvent sulfonation and special manufacturing processes assure very low TOC leakage.
Uniform Particle Size
98% of all beads are in the minus 16 to plus 40 mesh range: giving a lower pressure drop while maintaining the superior kinetics of standard mesh size products.
Superior Physical Stability
90% plus sphericity and high crush strengths together with a very uniform particle size provide greater resistance to bead breakage while maintaining low pressure drop.
Safety Information
A material safety data sheet is available for Aldex MB-1. Copies can be obtained from Aldex Chemical Co., LTD. Aldex MB-1 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.
