Buyer intent coverage
Bentonite — what it is, where it is used, how it is chosen
Bentonite is a swelling clay bought for what it does with water rather than for its chemistry. Sodium bentonite absorbs water and swells to form a gel, which is why it is used for sealing, drilling fluids and binding. Calcium bentonite swells far less and is used where adsorption and clarification matter more than gel strength. Buyers who ask simply for 'bentonite' almost always need the sodium/calcium question settled first, because the two are not substitutes for each other.
Primary uses
- Sealing ponds, landfill liners and civil works
- Building viscosity and filtration control in drilling fluids
- Binding foundry sands and iron-ore pellets
- Clarifying and decolourising oils and beverages with the appropriate grade
Applications
- Civil and environmental sealing projects across Western Canada
- Drilling and horizontal directional drilling operations
- Foundry green-sand systems
- Absorbent products, animal litter and agricultural amendments
Advantages
- One of the few minerals that delivers sealing and rheology at low cost per tonne
- Widely available across several industrial grades and pack formats
- Performs a structural job in systems where synthetic alternatives cost far more
Limitations to consider
- Sodium and calcium types are commercially distinct and must be specified explicitly
- Swelling behaviour is sensitive to water chemistry and to salt content
- Moisture pick-up during storage changes handling and dosing behaviour
- Addition level and performance are established on your own material and equipment; supplier literature values are starting points for a trial, not a specification.
- Mineral powders create airborne dust during transfer and bagging. Respirable crystalline silica content varies by mineral and by grade, so it is treated as an SDS and workplace-controls question rather than a published figure, and the SDS for the exact grade offered is the governing document.
How to choose the right grade
- Start from the function the mineral has to perform in your system, not from the mineral name
- State the particle size convention your specification uses, because mesh, micron and D50 are not interchangeable
- Decide whether the grade must be coated or uncoated before you shortlist suppliers
- Confirm the brightness or colour requirement if the finished product is white or light-coloured
- Confirm the regulatory framework the finished product sits under before qualifying a grade
- Suppliers report particle size in different conventions — mesh, micron top cut, or D50 from a stated measurement method. Compare like with like, and state the convention your specification uses when you enquire.
- Exact specification is confirmed against supplier documentation at quotation.
Typical grades
- Sodium bentonite grade
- Calcium bentonite grade
- Activated / bleaching-earth grade
- Foundry grade
- Granular and powder forms
- Coated (surface-treated) and uncoated grades of the same mineral behave differently in a formulation. Whether a specific offered grade is treated, and with what, is confirmed on supplier documentation at quotation.
- Reference grade names circulate as shorthand in enquiries and are treated here as search language only. An equivalent is established by comparing declared datasheet values and running a trial; no grade is presented as a drop-in replacement for another.
Comparable materials — how Bentonite sits against alternatives
- Attapulgite clay where salt tolerance is required
- Synthetic polymers for viscosity in drilling fluids
- Kaolin where sealing is not needed
- Buyers looking for an alternative or second-source supplier should state the incumbent grade and the property being matched. Mineral fillers are rarely interchangeable on name alone: comparison depends on declared datasheet values and on a plant trial.
Comparable-material reference. Grade selection is confirmed at RFQ against your process.
Procurement coverage
How to specify, order and receive Bentonite
Written for procurement, quality and technical buyers in Canada and the United States. No numeric price, MOQ, stock or lead-time value is published — those are confirmed per shipment in the quotation and against the confirmed batch.
How buyers specify at RFQ
- Mineral identity and the declared chemistry of the exact grade
- Particle size distribution — D50 and top cut — in the supplier's stated convention
- Coated or uncoated, and the surface treatment identity where treated
- Brightness or whiteness and the test method it is reported against
- Moisture, loss on ignition and residue on sieve as declared
- Bulk density and oil absorption where the process depends on them
Packaging options (industry-standard)
- 25 kg bag — the standard format for small and medium plants
- Jumbo / FIBC bag for compounding, dry-mix and blending operations that consume by the tonne
- Bulk truck or container load where the plant has silo intake and pneumatic discharge
- Packaging options and available pack sizes are confirmed with each quotation.
Storage & handling
- Store dry, sealed and off the floor; absorbed moisture changes flow, dispersion and dosing accuracy
- Protect bulk bags from condensation cycles between cold storage and a warm plant
- Rotate stock and record lot numbers against each production run for traceability
Documentation available
- Technical data sheet (TDS) for the exact grade offered, stating the declared particle size, brightness and moisture as the supplier reports them
- Safety data sheet (SDS) in the format required for Canadian import, including respirable dust guidance
- Certificate of analysis (COA) against the confirmed production lot
- Food-contact, feed or regulatory declaration where the end use requires it
- Documentation is confirmed per batch at quotation; availability depends on the grade and supplier offered.
RFQ checklist for bentonite-canada
Include these fields to receive an accurate Canada-landed quotation
- The material or system the mineral goes into, and the process it runs on
- The function you need it to perform and the problem you are trying to solve
- Particle size, brightness or purity window your specification calls for, in the convention your plant uses
- Annual volume and expected per-shipment quantity
- Packaging format your intake and feeding system can receive
- Documentation required per shipment
- Delivery province or port of discharge
- Whether you need a coated or uncoated grade
- The incumbent grade you are matching, if this is a second-source enquiry
- Whether your intake is bags, bulk bags or silo
- Mineral fillers 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, not ex-works.
Technical & procurement detail
Where bentonite is used+
Bentonite is a clay mineral used as a carrier, binder and flow aid in feed, fertilizer and industrial powder applications. Allzone reviews the intended formulation or process with the supplier before quoting so the correct grade is offered.
Food, feed, agricultural and industrial grades are not interchangeable+
Food grade, feed grade, agricultural grade and industrial grade materials are supplied and quoted as separate specifications. A product supplied for one segment is not presented as suitable for another. State the intended segment and application in your enquiry so the correct grade and documentation are reviewed with the supplier.
How specifications are confirmed+
Allzone does not publish assumed purity, active content, particle size, moisture, origin, certification, regulatory approval, packaging or price values. Grade, specification and documentation are confirmed in writing against supplier technical data sheets and safety data sheets before an order is placed.
Frequently asked questions
What grade of bentonite do you supply?+
The grade and specification are confirmed at quotation against the supplier technical data sheet. No purity, specification or certification value is published in advance.
Can I request a technical data sheet and a safety data sheet?+
Yes. Both the supplier technical data sheet and the safety data sheet for the quoted grade are provided on request and should be reviewed before purchase and use.
Do you deliver bentonite across Ontario and Quebec?+
Yes. Freight is arranged across Toronto, the GTA, Ontario, Quebec and Western Canada, and the delivery method is confirmed with the quotation.
What quantities can you supply?+
Quantities are reviewed per enquiry, from smaller lots to container loads.
