It is primarily used for water softening, pure water preparation, wet metallurgy, and as a polishing resin to remove trace metals and residual ions in high-purity water systems.
Resin should be kept in a wet state, ideally above 0°C. For long-term storage, it should be placed in a closed space or preserved in a salt solution of 5% or higher to prevent dehydration.
Yes, our food-grade resins are FDA compliant, ensuring they are safe and reliable for use in beverage, pharmaceutical, and food processing industries.
The resin is designed to maintain stability at maximum operating temperatures of up to 120°C.
In mixed-bed systems, 001x7.5 (cation) and MB 151 (anion) work together to remove both positively and negatively charged ions, resulting in ultra-pure water with extremely low conductivity.
Ensure proper filtration (sand-filtration) before the liquid enters the column to avoid jamming pores with suspended solids. Use wet packing or back-flushing to eliminate air bubbles within the resin layer.
