Import Activated Alumina ( 2-5mm Balls) — Buy in Bulk from Supplier in India

Activated alumina in 2-5 mm堂mm spherical bead form is a highly porous gamma-alumina (Al2O3) adsorbent produced via controlled calcination of aluminium hydroxide derived from bauxite feedstock. Pangea Chemicals Pvt. Ltd. lists this material with a particle size fraction of 2-5堂mm, placing it in the standard coarse-to-medium bead range favoured for fixed-bed adsorber vessels where low pressure drop and high geometric surface area are both required. The activation process, involving thermal treatment at 350-600 degrees Celsius, develops the characteristic mesoporous structure with typical surface areas of 200-400堂m2/g that define this adsorbent class.

The 2-5堂mm bead diameter suits applications where attrition resistance and uniform bed packing are critical, including compressed air drying, PSA gas separation units, and catalytic converter substrates. In industrial practice, this size fraction balances mechanical durability against diffusion path length; larger beads withstand higher superficial gas velocities but increase intraparticle transport resistance. The alumina phase is typically gamma-Al2O3 with delta-phase traces, offering reversible water adsorption through surface hydroxyl groups without structural degradation across hundreds of adsorption-regeneration cycles.

Primary buyers include petrochemical refineries, industrial gas producers, and water treatment operators requiring desiccant media for warm gas streams. Pangea Chemicals operates from India with a harbor-tier trust designation, though response metrics indicate no recorded buyer engagement. Importers should confirm with the supplier whether this material is offered as standard gamma-alumina or tailored for specific dew-point targets, and whether regeneration protocols are provided for cyclic operation.

Pangea Chemicals Pvt. Ltd. is an supplier with imported-tier classification based in India, operating under harbor-tier verification. The listing shows a response rate of 0.00% with zero average response hours, indicating no tracked buyer communication history within the platform's measurement period. No address, year of establishment, headcount, revenue, or client references are present in the available profile data.

The supplier's product offering centres on activated alumina with stated application across air purification, water treatment, gas separation, and catalysis sectors. The source description outlines a bauxite-to-activation production narrative but does not confirm captive manufacturing versus trading期盼 trade-only operations. Buyers should verify directly whether Pangea Chemicals manufactures this material, operates as a distributor, or sources through third-party refiners, and should request certificate of analysis samples before committing to bulk orders.
