Import 4a Molecular Sieve — Buy in Bulk from Supplier in China

Guangzhou Chemxin Environmental Material Co., Ltd. supplies 4A Molecular Sieve, an alkali alumino-silicate in sodium form, engineered for high-efficiency adsorption of polar molecules. This Type A crystal structure features a uniform pore size of 4 Ångströms, enabling selective removal of water, carbon dioxide, and hydrogen sulphide from gas and liquid streams. The material’s high chemical stability allows it to perform reliably in harsh industrial environments, such as high-temperature or corrosive conditions.

In industrial practice, 4A Molecular Sieve is standard for applications requiring deep drying, such as in air separation units, natural gas processing, and the production of insulated glass. Its ability to adsorb moisture at low partial pressures makes it particularly effective in systems where dew points below -40°C are required. The sieve is also used in the food and pharmaceutical industries for moisture control in packaging and as a processing aid. Typical regeneration temperature ranges from 200 to 300°C, allowing for repeated use cycles without significant degradation.

Buyers in petrochemical, food processing, and environmental engineering sectors rely on this sieve for its consistent performance in moisture removal and gas purification. The product is suited for bulk supply, with packaging designed to prevent moisture ingress during storage and transit. Trade terms, including incoterms and payment methods, should be confirmed directly with Guangzhou Chemxin Environmental Material Co., Ltd., as these are not specified in the listing.

Guangzhou Chemxin Environmental Material Co., Ltd. is based in Room 401, Changshanghui Building, No.31 Shengxing Street, Panyu District, Guangzhou, Guangdong Province, China. The company focuses on environmental materials, with a specialty in molecular sieves for industrial adsorption and separation applications. Its profile indicates an imported supplier tier with a harbor trust classification, signifying its engagement in cross-border trade.

The supplier’s listing does not provide response rates, average response times, or verified certifications, so buyers must proactively contact the company to confirm technical specifications and trade terms. No details on production capacity, quality control processes, or existing certifications such as ISO or SGS are stated.
