Engineered to deliver exceptional moisture control capacity across diverse technical applications.
Shanghai Jiuzhou Chemicals Co., Ltd. is located in the largest economic development city, Shanghai. Over the years, Jiuzhou has always adhered to the "Quality Control, Innovation" principles, committed to the development, research, and manufacturing of high-quality innovative chemical products.
Our main products include various molecular sieve powders, molecular sieves, activated powder, activated alumina, aluminum oxide catalysts, different types of alumina packing and ceramic balls, sodium silicates, aluminum hydroxide, zeolite 4A, sodium carbonates, SLES, etc. All of our products have successfully passed the ISO9001: 2008 quality management system certification, as well as TUV & SGS certifications.
Exploring the boundaries of advanced pore engineering, non-toxic indicators, and sustainable adsorption matrices.
By utilizing nanoscale engineering, we customize the internal pore distribution of A-type, B-type, and C-type silica gels. Controlling pore diameters down to 2-3 nanometers yields maximum static and dynamic moisture absorption capacities at lower relative humidities.
Aligned with REACH regulations, we develop alternative indicator matrices. Our organic-pigment indicator silica gels change color clearly without heavy metals like cobalt chloride, ensuring environmental safety and consumer-grade compliance.
Developing biodegradable packaging films (such as PLA and bio-based non-woven fabrics) for desiccant packets allows for a lower carbon footprint without compromising tensile strength or moisture-permeable efficiency.
The desiccant industry is transitioning from static preservation materials to smart components. JOOZEO is investing heavily in the development of hybrid, multi-functional desiccant matrices that combine high-capacity silica gel with molecular sieves and active carbon. This dual-action approach targets both trace water vapor and volatile organic compounds (VOCs) simultaneously, protecting highly sensitive optical systems and semiconductor elements.
Furthermore, our R&D team is piloting IoT-integrated packaging with optical humidity indicator sensors that allow non-invasive monitoring of humidity inside sealed industrial shipments.
How tailor-made desiccant configurations protect value and integrity across key global sectors.
In pharmaceutical applications, humidity control prevents active ingredient degradation, pill softening, and premature chemical reactions in diagnostics kits.
Humidity causes corrosion in micro-circuitry, copper leads, and multilayer PCBs. Our silica gel products ensure extreme dryness during shipping and storage.
Ocean voyages expose cargo to fluctuating temperatures, creating "container rain". We supply high-adsorption container desiccant bags that safeguard metal coils, agricultural products, and machinery components.
Sensitive aerospace instruments demand exceptionally dry microenvironments to prevent fogging, lens mildew, and corrosion of avionics circuits.
Shanghai Jiuzhou Chemicals utilizes cutting-edge manufacturing automation to ensure stable pricing, reliable lead times, and impeccable chemical purity. Our production lines integrate continuous drying, sizing, sorting, and packaging technologies that minimize environmental variability.
By optimizing raw material input channels and automating our quality control gates, we provide global OEM buyers with consistent product specifications, scaling our production to handle massive container-level demands seamlessly.
Exporting to all parts of the world, we have established robust distribution networks in the United States, Southeast Asia, Japan, Europe, North & South America, and the Middle East to provide partners with customized, eco-friendly adsorption solutions.

Get authoritative answers regarding silica gel selection, adsorption mechanics, and industrial configurations.
A-type silica gel has narrow pores (approx. 2.0-2.5 nm) and exhibits maximum moisture adsorption capacity at low relative humidity (RH < 35%). B-type has wider pores (approx. 4.5-5.0 nm) and adsorbs water better under high humidity (RH > 50%). C-type has very large pores (up to 7.0 nm) and is typically used for high-humidity applications or as catalyst carriers due to its open pore structure.
We enforce a strict raw material testing process. Our laboratory analyzes both the input raw materials and final packaging substrates using Gas Chromatography-Mass Spectrometry (GC-MS). This ensures that no Dimethyl Fumarate (DMF) or other restricted chemical agents are introduced during any phase of synthesis, drying, or distribution.
Yes, silica gel can be regenerated by heating the material to drive off adsorbed moisture. Heating non-indicating or cobalt-free indicating gel to approximately 105°C - 120°C for 2 to 4 hours will restore its drying capacity. Care must be taken not to exceed 150°C, as excessive heat can permanently collapse the delicate pore structure, neutralizing its adsorption functionality.
Our desiccants meet the performance specifications outlined in the MIL-D-3464E military standard. We also comply with industry regulations like HG/T 3927-2007 (for industrial alumina desiccants) and JB/T 10532-2017 (for pressure swing and adsorption drying machinery).
