Calcium Bentonite

It is used as an adsorbent and carrier — holding liquids, flavours or additives on a dry powder — as a binder in feed and pelletised products, as a clarifying and bleaching medium in oils and liquids, and as an absorbent base in cosmetic and industrial formulations. Whether a specific offered grade suits a particular duty depends on its declared surface properties and is established by trial on your own material, not assumed from this page.

The first decision is what the clay has to do — adsorb, carry, bind or clarify — because that sets whether a natural or an activated presentation is appropriate. After that, particle size and the percentage passing your stated mesh, moisture, pH, swelling behaviour, bulk density and the heavy-metal and documentation requirements of your sector decide the grade quoted.

Sodium bentonite is the swelling form used where gel strength, sealing and viscosity matter, and it has its own canonical page on this catalogue. Calcium bentonite is used where adsorption and clarification matter more than swelling. Calcium montmorillonite is the mineralogical name for the same material and is not a separate product. Activated, acid-activated and enzyme-treated presentations are processing variations of this material and are handled inside this record rather than published as separate pages, as are food grade, feed grade, cosmetic grade and industrial grade, and any mesh specification. Kaolin and zeolite are different minerals with their own records.

Suppliers report particle size in different conventions — mesh, percentage passing a stated mesh, micron top cut, or D50 from a named measurement method — and the numbers are not interchangeable between conventions. State the convention your specification uses, along with the property window you actually need, and comparison is made like for like. Moisture, pH, bulk density, swelling behaviour, heavy metals and any documentation requirement are reviewed the same way, against producer data for the grade offered.

This page asserts no purity, assay, mesh, micron, D50, brightness, swelling capacity, moisture, pH, bulk density, surface area, heavy-metal limit, origin, mine, packing, minimum quantity, certification, approval, availability, lead time or price. Every commercially meaningful value is taken from producer documentation for the exact grade offered and confirmed in writing before order.

Allzone sources this material through producer channels and quotes it per enquiry. Origin, mining location and processing location are selected against your technical requirement, quantity, documentation need and destination, and are stated in the offer rather than fixed by this page. Mineral powders have low value density, so freight, discharge point and packaging format move landed cost as much as the material price; quotations are compared delivered to your plant.

Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Mineral powders create airborne dust during transfer and bagging, and respirable crystalline silica content varies by material and by grade, so it is treated as an SDS and workplace-controls question for the specific grade rather than a figure published here. Where a declaration matters to your application — food contact, feed, potable water, cosmetic or regulatory — it is confirmed for that grade and intended use rather than assumed from this page.

Send the material or system it goes into, the process it runs on, the function you need it to perform, the property window your specification calls for in your own convention, the annual and per-shipment quantity, the packaging format your intake can receive, the documentation required per shipment and the delivery province or port. Several materials can be listed in one enquiry and reviewed together rather than split into separate requests.
