Import Bentonite Powder — Buy in Bulk from Supplier in India

Viswa Industries offers bentonite powder in 25kg and 50kg bag packaging, mined from natural sodium or calcium bentonite deposits located in India. The powder exhibits high swelling capacity and thixotropic behaviour, with typical montmorillonite content ranging from 60% to 85% for industrial grades used in drilling and foundry applications. The particle size distribution is fine, passing 200 mesh (75 microns) with a significant fraction below 20 microns to ensure rapid hydration and gel development in aqueous systems.

The mineral composition centres on hydrated aluminium silicate with exchangeable sodium or calcium cations, dictating whether the bentonite is classified as sodium bentonite (high swelling, Western Indian deposits) or calcium bentonite (lower swelling, more common in Eastern deposits). Typical moisture content at point of packaging sits between 8% and 12%, with a pH of 8.5 to 10.5 in 5% suspension. The powder's plasticity index and liquid limit determine its suitability for specific binding or sealing tasks, with sodium grades generally favoured for drilling muds and calcium grades for foundry moulding.

Primary buyers include oilfield service companies formulating drilling fluids, foundries producing iron and steel castings, and civil engineering contractors installing bentonite slurry walls or landfill liner systems. The powder also serves ceramic manufacturers, pet litter producers, and wastewater treatment operators. Trade terms require direct confirmation with Viswa Industries, as the listing does not specify MOQ, incoterms, or lead time. Buyers should request a certificate of analysis for each batch to verify montmorillonite content, swelling index, and methylene blue index before finalising orders.

Viswa Industries operates from Balaji Nager Housing Board in Kukatpalli, Hyderabad, within the state of Andhra Pradesh, India. The supplier holds an imported tier designation and a harbor trust tier, indicating limited verification depth on the platform. The response rate stands at 0.00% with zero average response hours recorded, which suggests the listing may be passively maintained or that response metrics have not yet populated. No factory ownership, year of establishment, or employee count is stated in the available profile.

The company lists bentonite powder as its offered product, with bagged packaging options and an emphasis on industrial applications spanning drilling, foundry work, and environmental sealing. The profile does not disclose production capacity, in-house testing facilities, or third-party accreditation. Buyers should treat claims of ISO certification as unverified from this source and request current certificates directly. Given the response data, initial contact through the platform may yield delayed replies, so buyers might consider supplementary due diligence via direct outreach to the Hyderabad address.
