Leading the industry in synthetic materials for advanced water purification. Delivering high-capacity ion exchange resins designed for maximum chemical stability and operational longevity.
Setting the global standard for high-purity synthesis and ion exchange efficiency.
◆ As a pioneer in ion exchange resins for water purification, we specialize in Gel Polystyrene structures crosslinked with divinylbenzene. Our position in the synthetic materials market is defined by an unwavering commitment to chemical purity and mechanical strength, ensuring that every bead provides optimal exchange capacity.
◆ Our ion exchange resins for water purification leverage Quaternary Ammonium functional groups to achieve a weight exchange capacity of ≥3.6mmol/g. This technical edge allows for Ultra-Pure water preparation, drastically reducing regeneration cycles and operational costs for industrial wastewater treatment plants.
Engineered for durability, high selectivity, and exceptional kinetics in water treatment.
Advanced cross-linking ensures minimal resin degradation under osmotic shock.
Rapid exchange rates achieved through high functional group density.

Expert answers to common technical and commercial inquiries.
Lifespan is optimized by implementing strict pre-filtration (sand filtration/flocculation) to prevent organic fouling and following precise regeneration velocities (1-2BV/h).
For our strong-base resins, we recommend a sequence of 2BV 3-5% HCl followed by 2BV 2-4% NaOH to ensure complete functional group recovery.
Resins must be kept in a wet state. For long-term storage, add 5% salt water and store in a closed space above 0℃ to prevent drying or freezing.
Due to our tight uniformity coefficient (≤1.6), the pressure drop is significantly lower than standard resins, allowing for higher flow rates without bed compaction.
Ensure you calculate the transformation expansion rate. We recommend leaving sufficient freeboard space in the column to accommodate the resin bed's expansion.
Yes, they are specifically designed for industrial wastewater. However, for high-suspended solids, we require pre-filtration to avoid jamming the resin pores.
