Resintech MBD-30 Nuclear Grade Mixed Bed DI Resin, 2.27 kg, Self-Indicating

Resintech MBD-30 is nuclear-grade mixed bed DI resin for producing demineralized water, supplied as a 5 lb (2.27 kg) blend designed to deliver resistivity above 10 megohm.

• One 5 lb bag — provides resin for refilling four 10 inch (25.4 cm) clear refillable filters.
• Combined cation and anion resins — supplies both exchange components in one mixed bed.
• Self-indicating color change — lets users monitor resin exhaustion through a clear housing.
• Made in the United States — provides a stated country of origin.
• Nuclear-grade resin blend — uses hydrogen-form cation resin and hydroxide-form anion resin.

For processes that need demineralized water, choosing resin with a visible exhaustion cue can make cartridge changes easier to monitor. Resintech MBD-30 is intended for clear, see-through cartridge housings, including applications where a system relies on the resin’s color rather than a meter. Its stated applications include manufacturing wash, rinse, and test processes that require high-purity water.

What water quality is Resintech MBD-30 designed to provide?

Resintech MBD-30 is designed to produce demineralized water with resistivity in excess of 10 megohm. This makes it suitable for processes requiring multi-megaohm resistivity, where the stated need is high-purity water rather than the ultimate possible water quality. Actual water quality depends on how the cartridge is configured.

• Designed for cartridge applications with clear, see-through housings.
• Used for manufacturing wash, rinse, and test purposes.

How does the color indicator show when the resin is exhausted?

Resintech MBD-30 changes appearance as its resin becomes exhausted, allowing visual monitoring in a transparent cartridge. The anion resin contains an indicator dye that changes from blue to colorless as that resin exhausts; the mixed bed’s overall appearance shifts from green toward violet.

In a typical setup, a safety line is positioned at the cartridge’s exit end. When the color change reaches that line, the cartridge is considered exhausted and is exchanged for fresh resin. This visual indication is intended for systems designed to operate without meters.

• The product color is identified as green or black.
• The indicator provides a visual cue through a clear housing.

What is in the mixed bed, and how much does the bag refill?

Each bag contains a single blend of strong-acid cation exchange resin and strongly basic anion exchange resin. The cation component is a sulfonated polystyrene gel resin; the anion component is a Type I strongly basic gel resin.

The blend combines hydrogen-form cation resin with hydroxide-form anion resin, so both exchange components are included together rather than supplied as separate media. One bag is enough to refill four 10 inch clear refillable filters.

• Material: DI resin.
• Contents: one bag of mixed bed resin.

Can Resintech MBD-30 support a continuous supply?

Two cartridges connected in series can provide a constant supply of high-purity water. The resin is used in cartridge-based systems, and the final water quality depends on the cartridge configuration.

For a visual-monitoring setup, place the resin in a clear housing and use the color change at the cartridge’s exit-end safety line as the exhaustion cue. The cartridge is considered exhausted when that change reaches the line and can then be exchanged for a fresh cartridge.

• Made for cartridge applications using clear housings.
• Two cartridges in series can provide a constant supply.

Resintech MBD-30 suits manufacturing and other cartridge-based processes that need demineralized water and benefit from a visible exhaustion indicator. It is a practical fit for users filling clear refillable filters and monitoring resin condition without a meter; its mixed bed combines both cation and anion exchange resins in one bag.
