Import Carbon Molecular Sieve (Cms) — Buy in Bulk from Supplier in China

Carbon Molecular Sieve (CMS) from Dalian Chem Imp.& Exp. Group Co., Ltd is a nonpolar sorbent designed to adsorb oxygen molecules at normal temperatures under swinging pressure, producing enriched nitrogen gas. The material exploits the differential diffusion rates and adsorptive capacities of gases in air to achieve separation. Key models supplied include CMS-185, CMS200, and CMS220, each tailored for specific industrial nitrogen generation requirements.

The product is available in grain diameters of 1.5mm and 2.0mm, with an absorption period of 260 seconds and a pile proportion of 630 to 650 g/L. Its bearing strength is rated at 100N per grain, ensuring durability in high-pressure applications. Carbon molecular sieves are standardly used in petroleum chemical processing, metal heat treatment, electronics manufacturing, and food preservation, where nitrogen purity and flow rates are critical.

Industrial buyers source this CMS for PSA nitrogen generators, where it serves as the core adsorbent. The material’s cylindrical black solid form contains 4 angstrom fine pores, enabling efficient separation of oxygen and nitrogen. Typical applications include chemical inerting, electronics assembly, and controlled-atmosphere packaging. Buyers confirm bulk density, crushing strength, and adsorbent time with the supplier to match their generator specifications.

Dalian Chem Imp.& Exp. Group Co., Ltd is based in Chem Bldg, No.61, Renmin Road, Dalian, Liaoning, China. The company operates as an imported-tier supplier with a harbor trust tier, indicating a verified address and basic trade credentials. Its profile lists no active response metrics, so buyers should expect to initiate contact directly for technical and trade inquiries.

The supplier specializes in carbon molecular sieves for industrial gas separation, with a focus on models like CMS-185, CMS200, and CMS220. While the profile does not disclose production capacity, certifications, or client lists, it confirms the availability of multiple CMS grades. Buyers are advised to request updated test reports and application-specific data before committing to large orders.
