Founded in 1981, Purolite has established itself as a premier supplier of specialty resins for global markets, including ion exchange, catalysts, absorbents, and other specialized applications. The company operates manufacturing facilities in Philadelphia, USA; Victoria, Romania; and Hangzhou, China. Purolite's products find extensive use in various sectors such as pharmaceutical manufacturing, microchip production, potable water treatment, chemical processing, refining, catalysis, food and beverage production, metal extraction, metal finishing, electroplating, nuclear power generation, chromatographic separation, and adsorbent chemistry. Below is a selection of their products:
Purolite® MPR1000
This proprietary blend of patented resins is engineered to minimize membrane fouling by eliminating colloidal and organic substances from feedwater. It has been shown to reduce the feedwater silt density index (SDI) by over 40% and total organic carbon (TOC) by up to 85%, achieving SDI values as low as 1.5.
Purolite® TANEX
A specialized blend of patented anion exchange resins designed for the removal of tannins and organic matter from water, primarily for potable applications. Purolite TANEX effectively reduces challenging organic matter and color that may exist in both partially dissolved and colloidal forms.
Purolite A300
This Type 2, strongly basic gel anion exchange resin offers exceptional operating capacity and regeneration efficiency. Purolite A300 removes all ions, including silica and CO2, and is particularly effective with water that has a high concentration of strong acids (FMA). It is suitable for all types of demineralization equipment requiring high regeneration efficiency and capacity.
Purolite A400E
A clear gel Type 1 strong-base anion exchanger that combines high operating capacity with the ability to achieve low residual silica levels. Compared to conventional Type 1 (Purolite A600) quaternary ammonium structures based on polystyrene, it requires minimal amounts of caustic soda. Its clear gel structure ensures excellent regeneration efficiency and rinsing properties.
Purolite A520E
This macroporous strong base anion resin is specifically designed to remove nitrates from water for potable applications. Its macroporous matrix and unique ion exchange group functionality provide optimal nitrate selectivity, making Purolite A520E particularly effective even in the presence of moderate to high sulfate concentrations.
Purolite A530E
A specially selected macroporous strong base anion resin crosslinked with divinylbenzene, designed for hydrophobic anions. It demonstrates strong mechanical strength and excellent resistance to osmotic and thermal shock. The resin's macroporous structure and unique ion exchange group functionality give it exceptional selectivity for perchlorate and pertechnetate.
Purolite C100E
This high-purity premium grade bead form of conventional gel polystyrene sulfonate cation exchange resin is specifically designed for treating food products, beverages, and potable water, as well as water used in food processing. Its specifications exceed relevant EEC standards and comply with U.S. Food & Drug Administration regulations.
Purolite C100EH
An exceptionally pure premium grade of conventional gel poly(styrene sulfonate) cation-exchange resin, specially manufactured for the demineralization of solutions intended for potable use or treatment of food products, beverages, and potable water.
Purolite SST60
A high-efficiency softening resin utilizing shallow shell technology. This approach shortens the diffusion path, leading to faster softening exchange rates, particularly during regeneration. By reducing the depth of penetration required for resin cleansing, it allows for more complete regeneration and enhances the effective use of the regenerant.
