Our minimum order quantities are: 1 truckload (approximately 25–26 tons, big-bag packaging) 1 container (20'DC or 40'HC options) Packaging options: 25 kg kraft bags, 1000 kg big-bags, or custom packaging according to customer requirements.

The activation process increases the surface area by replacing the cations in bentonite crystals with protons and partially dissolving the octahedral layers.

Our feed bentonite production is carried out in compliance with the following regulations: EFSA (European Food Safety Authority) – Nutritional safety assessments FDA (U.S. Food and Drug Administration) – GRAS (Generally Recognized As Safe) status EU 1060/2013 – Approval of bentonite as a feed additive Republic of Türkiye Council of Ministers Decision (BKK) – Feed additives regulation ISO 9001:2015 – Quality management system Our products are regularly tested for heavy metal limits such as arsenic, lead, and cadmium, as well as for aflatoxin B1 binding capacity.

Bleaching earth is a derivative of activated bentonite used in the recovery of waste oils and in the refining of edible oils. For technical details, activation degree, acid activation parameters, and specific application formulations, please contact our R&D Center.

Our products used as paint bentonite provide the following rheological and physical properties: Thixotropy: Flow during brush or roller application, gels when at rest Dispersion stability: Prevents pigment settling Sedimentation control: Maintains homogeneous distribution during storage Film thickness control: Prevents sagging and dripping Anti-matting: Preserves surface gloss Calcium bentonite shows effectiveness in both water-based and solvent-based systems with appropriate surface modification.

Calcium bentonite is used in cosmetic formulations with the following functional properties: Skincare: Adsorption of oils and impurities in facial masks, pore cleansing Haircare: Detoxification of the scalp and oil-balancing effect in shampoos Viscosity modifier: Provides gel-like consistency Natural and purifying: Contains nourishing minerals Our high-purity calcium bentonite is processed in compliance with cosmetic regulations (EC 1223/2009).

As a feed additive, calcium bentonite provides the following nutritional physiology effects: Mycotoxin binding: Adsorption of fungal metabolites such as aflatoxin and ochratoxin Digestive system regulation: Optimization of intestinal transit time Nutrient bioavailability: Increased feed efficiency Rumen buffer: Maintains acid-base balance (especially in ruminants) Our products are produced in compliance with EFSA (European Food Safety Authority) and relevant Turkish regulations (BKK).

In foundry applications, bentonite serves as a mold sand binder: Plasticity: Provides cohesion to sand grains, enabling mold shaping Thermal resistance: Maintains structural integrity at casting temperatures Reusability: Can be recovered through mechanical regeneration after casting Surface quality: Reduces surface roughness of the cast metal part Sodium bentonite is preferred in heavy castings and automated molding lines due to its high swelling capacity and binding strength.

In oil and geothermal drilling, bentonite mud performs the following key functions: Wellbore stabilization: Prevents fluid and gas leakage from formations Suspension property: Carries cuttings to the surface Cooling and lubrication: Reduces drill bit temperature Hydrostatic pressure: Balances formation pressure to prevent well collapse Our products are manufactured in compliance with API (American Petroleum Institute) and OCMA (Oil Companies Materials Association) standards, offering high viscosity, low filtrate water, and optimal yield point/plastic viscosity ratio.

Sodium bentonite forms a high-viscosity gel as the interlayer spacing increases upon contact with water, whereas calcium bentonite exhibits a more stable, low-swelling structure. Selecting the correct type in industrial applications is critical for process efficiency.

Bentonite is a clay mineral formed by the geological alteration of volcanic ash and tuffs, with its main component being montmorillonite. Montmorillonite is a 2:1 layered silicate mineral of the smectite group, whose unique crystal structure imparts high adsorption capacity, ion exchange ability, and colloidal properties to bentonite.

Yes. Our bentonite production is carried out through an integrated plant model. We process the raw material extracted from our own mines in our factories to produce the final product. This vertical integration allows us to maintain quality control at every stage of production and ensures continuity in the supply chain.
