AmberTec MR-300 UPW H OH

Summary

Product Identification

AmberTec™ MR-300 UPW H/OH Ion Exchange Resin is a separable, uniform particle size, mixed bed ion exchange resin. It is an ultrapure water-grade, mixed resin recommended as a working or polishing mixed bed for demineralization and final polishing in the semiconductor industry.

Historically, this product was sold as DOWEX MONOSPHERE™ MR-3 UPW Ion Exchange Resin.

Applications

• Regenerable, polishing mixed bed
• Working mixed bed following reverse osmosis
• Non-regenerable, polishing mixed bed
