Zeolite 4A is a synthetic crystalline sodium aluminosilicate with a three-dimensional framework structure. Its unique molecular pore structure, which measures approximately 4 Angstroms (0.4 nm), defines its function as a highly selective molecular sieve. In the chemical process industry, Zeolite 4A is the primary builder replacing environmentally hazardous sodium tripolyphosphate (STPP) in powder detergents, preventing eutrophication in aquatic ecosystems.
The chemical formula for Zeolite 4A is represented as Na12[(AlO2)12(SiO2)12]·27H2O. The fundamental mechanism driving its industrial efficiency is its high calcium ion exchange capacity (CEC). In water treatment and laundry washing cycles, Zeolite 4A selectively traps divalent calcium ions (Ca2+) and magnesium ions (Mg2+), replacing them with sodium ions (Na+). This action effectively softens hard water, optimizing the performance of active surfactants.
Additionally, the thermal stability, chemical inertness, and non-toxic properties of high-grade synthetic Zeolite 4A make it an indispensable raw material for various structural catalysts, gas separators, and industrial molecular sieve formulations.
Shanghai Jiuzhou Chemicals Co., Ltd. (Joozeo) has consistently pioneered innovations in the chemical desiccant and adsorbent industry. Centered on high-quality production, our integrated processes are designed to serve advanced industrial applications globally.
Located in the prominent economic hub of Shanghai, Jiuzhou has adhered to the principles of strict quality control and perpetual technological innovation. We are committed to the research, development, and manufacturing of premium, innovative chemical products. Our diversified portfolio includes molecular sieve powders, molecular sieves, activated powder, activated alumina, aluminum oxide catalysts, various types of alumina packing and ceramic balls, sodium silicates, aluminum hydroxide, zeolite 4A, sodium carbonates, and SLES.
All manufacturing facilities operate under strict compliance with the ISO9001: 2008 quality management system, and our products carry renowned TUV & SGS certifications. Supported by a world-class chemical research team, our facilities feature modern multipurpose plants and a state-of-the-art central analytical laboratory equipped with high-precision monitoring instruments.
As a trusted partner in energy-saving and environmentally friendly adsorption solutions, our distribution network spans across the United States, Southeast Asia, Japan, Europe, North and South America, and the Middle East.
By operating two large-scale manufacturing facilities in Shanghai and Wuxi, JOOZEO secures high-capacity output and supply chain reliability for multinational enterprises.
Our primary Shanghai hub leads research and production of fine desiccants, activated powders, and advanced synthetic zeolites, complying with national environmental guidelines.
The Wuxi production base specializes in mass crystallization, large-volume raw material preparation, and bulk-load packaging logistics to ensure prompt dispatch.
Our proximity to direct sources of premium sodium silicate (water glass) and aluminum hydroxide keeps chemical precursors pure, reduces transportation overheads, and shields pricing from raw material market fluctuations.
We implement automated hydrothermal crystallization processes. This level of control produces a uniform particle size distribution (PSD) centered at 2–4 microns, minimizing primary crystal aggregation and keeping liquid carrying capacity high.
Our 25,000 square meter facility generates high economies of scale. High-throughput synthesis allows us to offer competitive global quotes for Zeolite 4A without sacrificing crucial specifications like calcium exchange rate or pH buffering capacity.
Zeolite 4A is widely utilized in diverse industries. We supply specialized grades tailored to unique macro-environmental and process-specific conditions.
As regulations against phosphates tighten globally, Zeolite 4A has become the industry standard for builder applications. Its calcium exchange capacity (≥ 295 mg CaCO3/g dry basis) effectively sequesters mineral hardness in wash water, enhancing surfactant performance and protecting washing machine components from scaling.
High-purity Zeolite 4A powder acts as the structural foundation for specialized molecular sieves. Through ion exchange with potassium (K+) or calcium (Ca2+), we transform the base 4A framework into 3A (pore size 0.3 nm) or 5A (pore size 0.5 nm) variants, serving critical natural gas dehydration, ethanol drying, and pressure swing adsorption (PSA) gas separation operations.
In environmental engineering, Zeolite 4A serves as an effective cation exchanger for industrial wastewater treatment. It selectively binds heavy metal ions (such as Pb2+, Cd2+, and Cu2+) and radioactive isotopes (like Cs137 and Sr90), locking them securely within its crystal structure for safe disposal.
Zeolite 4A is used as a thermal stabilizer in PVC processing. By adsorbing trace hydrogen chloride (HCl) generated during thermal degradation, it prevents polymer discoloration and deterioration, replacing toxic lead-based stabilizers in green construction materials.

JOOZEO is committed to clean air, water purification, and sustainable chemical processes. We design our industrial operations to minimize ecological footprints.
When sourcing Zeolite 4A at scale, enterprise procurement managers evaluate several key technical criteria beyond basic pricing. Consistent performance in detergents, molecular sieve production, or water treatments requires meeting strict chemical boundaries:
Must exceed 295 mg CaCO3/g on an anhydrous basis. If this drops, surfactant efficacy decreases in hard water regions, leading to lower detergent quality.
An average diameter (D50) of 2.0 to 4.0 microns is ideal. Particles over 10 microns can leave white, insoluble deposits on dark clothing, which leads to consumer complaints.
Higher oil and surfactant absorption metrics (typically > 22g/100g) allow liquid surfactants to blend smoothly into dry powder detergents without clumping.
The 1% dispersion pH should remain stable between 10.0 and 11.0. This stabilizes the chemical environment, protecting fabrics from chemical degradation during wash cycles.
JOOZEO supports bulk distribution channels with container optimization strategies. We offer moisture-barrier jumbo bags (typically 650kg or 1000kg) and standard 25kg PP/PE bags. These options keep our products dry and free-flowing during maritime shipping across high-humidity routes.
