Discover the MADUR Series for
the Right Product and High Performance

MADUR Series by NB Global is produced from Türkiye’s rich bentonite reserves, processed through advanced activation techniques to enhance the surface area and pore structure of the clay.

These products are used in the refining of vegetable and animal oils, as well as in biodiesel, mineral oil, and paraffin applications. They effectively remove colour pigments, unpleasant odours, phosphatides, soap, and other impurities from crude oils.

The MADUR Series offers several advantages over its counterparts. Bleaching earths are derived from bentonitic clays whose adsorption capacity is increased through natural or acid activation.

With features such as high surface area and optimized pore size, they are widely preferred in oil refining. The MADUR Series combines carefully selected bentonite blends to deliver both high activity and superior filterability.

• Provide excellent adsorption through high surface area and optimized pore size,
• Improve filtration system efficiency thanks to optimum particle size distribution,
• Deliver high performance at low dosage, resulting in less waste and lower operational costs.

At NB Global, we offer high performance, reliability, and quality in refining processes with our MADUR series bleaching earths, specifically developed for various types of oils. Each product is optimized for specific needs and designed to meet key industry requirements in terms of food safety, high adsorption capacity, and process efficiency.

The MADUR series is preferred by oil refineries around the world, as it contributes to more efficient, cleaner and more cost-effective refining operations, supported by our technical consultancy services.
