4a Zeolite

GRCC’s 4A Zeolite is an industrial-grade aluminosilicate with a uniform pore structure of approximately 4 Å, making it highly effective for selective adsorption of small molecules. The material is supplied as a fine white powder with a typical particle size distribution of 1 to 5 microns, optimised for rapid ion exchange in liquid systems. Its chemical formula, Na12[(AlO2)12(SiO2)12]·27H2O, ensures high stability in aqueous environments, a critical feature for water treatment applications.

The zeolite’s ion-exchange capacity is typically measured at 300 to 350 mg CaCO3 per gram, a standard benchmark for 4A type materials used in detergent and water softening formulations. It exhibits low solubility in water and maintains structural integrity up to 400 °C, a typical thermal threshold for industrial zeolites. The product is free from heavy metals and has a moisture content of less than 2% by weight, aligning with common industry specifications for bulk supply.

This grade is primarily used in municipal and industrial water softening, where it removes calcium and magnesium ions to prevent scaling in pipes and equipment. Detergent manufacturers incorporate it as a builder to enhance cleaning efficiency by binding hardness ions. Agricultural applications include soil amendment to improve nutrient retention and as a feed additive to bind mycotoxins. Buyers typically source it in 25 kg or 50 kg multi-layer paper bags with PE inner liners, and bulk shipments are palletised for export.

GRCC is based in Heze, Shandong Province, China, and operates as a supplier of industrial minerals, including zeolites, for bulk export. The company’s profile indicates a focus on providing materials for water treatment and chemical processing industries, with a stated ability to handle large-scale orders for international buyers. Its harbor-tier trust status reflects a baseline level of verification for export readiness.

The supplier does not disclose specific certifications, production capacity, or response metrics in its profile. Buyers are advised to confirm quality control measures, batch consistency, and compliance with relevant standards such as ISO or SGS directly with the supplier. GRCC’s location in Shandong, a key industrial hub, may offer logistical advantages for shipping to major ports such as Qingdao.
