Highly engineered desiccants and molecular sieves designed for specialized industrial operations.
Understanding the chemistry, pore geometries, and thermodynamics of modern high-purity silica gel desiccant technologies.
At the core of silica gel's performance is synthetic, amorphous silicon dioxide ($SiO_2$). Highly porous with an interconnected network of microscopic pores, silica gel exhibits an extremely high specific surface area, typically ranging from 650 to 800 $m^2/g$. Through capillary condensation and physical adsorption, water molecules are trapped inside the silica matrix, maintaining low relative humidity levels in sealed spaces.
Our raw materials are classified into Type A (fine-pored, optimized for low humidity applications with high absorption rates at relative humidity below 40%), Type B (medium-pored, suited for relative humidity buffer systems), and Type C (wide-pored, displaying outstanding capabilities for liquid water absorption and high-moisture buffering environments).
Unlike chemical desiccants, silica gel features a completely reversible adsorption process. Because it operates strictly on physical adsorption (van der Waals forces), it can be regenerated repeatedly at thermal thresholds between 120°C and 150°C. This makes our high-durability products extremely energy efficient and circular, cutting total operational costs across shipping and warehousing applications.

Professional answers regarding adsorption capacity, chemical compatibility, and procurement dynamics.
Under static equilibrium conditions at 25°C and 90% Relative Humidity, our Type A Silica Gel JZ-BSG reaches a maximum moisture adsorption capacity of ≥32% to 35% of its dry weight. For environments with high humidity spikes, our specialized Type B silica gel composites can adsorb over 40% of their weight in liquid water.
All JOOZEO products are fully certified compliant with REACH and RoHS standards. We do not use cobalt chloride (a suspected carcinogen) as a moisture indicator. Instead, our blue-to-pink and orange-to-green indicating silica gels use non-toxic, eco-friendly metal salt formulas to guarantee safety during disposal and handling.
Our silica gel desiccant pricing fluctuates based on raw sodium silicate costs, desired particle size distributions, packaging material specifications (e.g., standard composite paper, Tyvek, or non-woven fabric), and total shipping weight. Please contact our sales team directly for customized FOB, CIF, or DDP pricing lists.
Yes. Because physical adsorption does not alter the underlying chemical structure of $SiO_2$, it can be repeatedly regenerated by baking at 120°C–150°C for 2–3 hours. However, repetitive thermal cycling may gradually break down its micro-pore structure, leading to a slow decrease in adsorption efficiency after several dozen cycles.
