DuPont™ AmberTec™ MR-450 UPW H/OH Ion Exchange Resin
As a flagship mixed bed ion exchange resin under DuPont’s ultrapure water (UPW) product line, AmberTec™ MR-450 UPW H/OH is tailor-made for the semiconductor industry’s strict water quality demands. This non-separable, homogeneous mixed bed resin integrates high-purity performance, long service life, and efficient impurity removal, enabling sub-ppb level removal of soluble silica, boron, sodium, and heavy metals. It is the core material for point-of-use (POU) polishing loops in semiconductor manufacturing, ensuring ultrapure water meets the most rigorous production standards. For enterprises pursuing stable, efficient, and low-maintenance water treatment, this resin is the ultimate choice.
Why Choose DuPont™ AmberTec™ MR-450 UPW H/OH?
1. Sub-Ppb Level Purification, Meeting Semiconductor-Grade Standards
• Comprehensive Impurity Removal: Targets key contaminants in ultrapure water, including soluble silica (≤0.1 ppb), boron (≤0.5 ppb), sodium/potassium (≤0.1 ppb), sulfate/chloride (≤0.1 ppb), and heavy metals (iron, aluminum, zinc ≤0.1 ppb). Fully complies with SEMI F63-0308 and ASTM D1125 ultrapure water standards for semiconductor manufacturing.
• High Ionic Conversion: ≥95.0% conversion to active ionic sites (H⁺ for cation, OH⁻ for anion), ensuring no residual impurities from the resin itself. The treated water resistivity can reach 18.2 MΩ·cm, with total organic carbon (TOC) ≤5 ppb—critical for advanced chip (≤7nm) production.
2. Non-Separable Design, Stable & Low-Maintenance
• Anti-Layer Separation: Cation resin (360±50 μm) and anion resin (590±50 μm) have optimized particle size matching, preventing separation during installation, backwashing, or long-term operation. Eliminates uneven purification caused by resin stratification, ensuring consistent water quality.
• Long Service Life: As a non-regenerable mixed bed, it maintains high performance for 2–3 years before replacement—2–3 times longer than ordinary mixed bed resins. Reduces downtime for resin replacement and lowers maintenance costs by 40–50%.
3. Efficient Kinetics, Saving Energy & Water
• Fast Rinse Performance: Excellent rinse characteristics (shown in Figure 2) allow rapid stabilization of water quality after resin replacement. Only 20–30 bed volumes of rinse water are needed to reach target resistivity, saving 50% of rinse water compared to conventional resins.
• Low Pressure Drop: Optimized particle size distribution ensures low system pressure drop (Figure 1). At a service flow rate of 10–30 m/h, the pressure drop is only 0.05–0.1 kg/cm²/m, reducing energy consumption of water pumps by 15–20%.
4. Strict Quality Control, Reliable for Critical Processes
• Semiconductor-Grade Purity: Manufactured in a cleanroom environment with specialized impurity removal processes. Metal impurities (Na ≤20 mg/kg, Fe ≤10 mg/kg, Cu ≤5 mg/kg) are controlled to ultra-low levels, avoiding "killer defects" in semiconductor wafers.
• Consistent Batch Quality: Each batch undergoes rigorous testing (resistivity, TOC, impurity content) to ensure performance uniformity—critical for large-scale semiconductor production lines requiring stable water quality.

FAQ
Q1: Can this resin be used in high-temperature ultrapure water systems?
A1: The optimal operating temperature is 15–25°C. Operating above 60–70°C may reduce resin life and increase impurity leaching. For high-temperature scenarios (e.g., 40–50°C), consult our team for customized parameter adjustments.
Q2: How to confirm when the resin needs replacement?
A2: Monitor water quality indicators (resistivity <18 MΩ·cm, silica >0.5 ppb, or TOC >10 ppb) or use the recommended 2–3 year service life as a reference. We provide free water quality testing kits to help track resin performance.
Q3: Does it require special equipment for installation?
A3: No. It is compatible with standard mixed bed columns (stainless steel or PVDF 材质). Our team provides a detailed installation guide, including pre-rinse steps and flow rate settings, to ensure smooth commissioning.
