CURRENT RANGE
API & OCMA bentonite
Our current commercial range covers API and OCMA bentonite. Start with the required specification, then discuss the right tier.
Swipe across to compare the four commercial tiers →
API High Yield
For enquiries focused on slurry yield.
Define the required slurry yield, its units and test endpoint. Compare sample results before selecting this commercial tier.
Understand the specificationOCMA Standard
A starting point for OCMA-based enquiries.
Review the OCMA reference requirements alongside the intended drilling or engineering use.
Understand the specificationOCMA Premium
For enquiries with additional performance targets.
State the properties your project needs beyond its baseline specification. Confirm the proposed tier against sample and batch data.
Understand the specificationHow to read these names: Standard, High Yield and Premium are commercial labels, not official API / OCMA subgrades. Tier-specific performance is pending verification; the label alone does not establish a performance difference.

A MATERIAL, MANY DIFFERENT REQUIREMENTS
Start with the application, not a single “best” grade.
Drilling, foundry, pelletizing and sealing applications evaluate different properties. A strong result in one test does not establish suitability for every use.
- 01 · Identify the useWhat must the material do in your process?
- 02 · Define the testWhich method, units and conditions apply?
- 03 · Evaluate the sampleDoes it work with your water, raw materials and equipment?

From bag to receiving site.
Choose around your receiving equipment, storage and use. Explore site photographs and bag-format illustrations; the final bag construction is agreed with your order.
PACKING · PROTECTION · HANDLING
From packed bags
to pallet handling.
Bag format is one part of the discussion. Pallet arrangement, wrapping and receiving conditions also belong in the packing specification.
Photographs show site examples. Packing for your order is confirmed in the agreed specification.
01 / BULK FORMAT
Jumbo bags
1 MT option
For bulk receiving and controlled discharge.
A format to discuss when the site has suitable lifting equipment and a defined unloading process.
