Earth’s most abundant renewable resource is cellulose, an organic polymer and main building material in all plants. Using this natural raw material Weidmann Fiber Technology produces microfibrillated cellulose for novel and engineered applications.
Plant based fibers, like wood pulp, are the source of more than 5000 industrial products world-wide. They are commonly used for paper and board production with various fields of application. And, with intensive defibration of the macroscopic fiber structure, smaller elements called fibrills can be separated and offer an even wider range of application. This material is often called micro fibrillated cellulose, cellulose fiber fibrills or cellulose micro fibrills.
Weidmann MicroFibrillated Cellulose (WMFC) is a product based on high quality pulp and carefully separated cellulose fibrills with high aspect ratio and narrow particle size distribution. WMFC is free of chemical side groups, it shows a neutral pH and low conductivity. Based on the requirements of our customers, WMFC can be made of several raw materials like wood pulp or fiber from perennial plants. It can be offered in different defibration qualities.
Weidmann Fiber Technology has commissioned its pilot facility in August 2015 and is now proud to be able to provide its range of materials to the market.

For applications requiring unique characteristics we provide WMFC Q_advanced. The product is characterized by high water retention properties, very low non-organic contamination and a narrow particle size distribution in combination with fibrils showing both a high aspect ratio and high viscosity.
WMFC Q_eco is made of plant fibers grown and processed according to EMAS and ISO 9001. A gentle defibrillation without the use of any chemical additives produces a microfibrillated cellulose with a wide distribution of fibril sizes and a neutral pH. WMFC Q_eco is perfectly suited e.g. for filters, as structural elements in paints and as strengthener in paper or board.
Weidmann Fiber Technology partners with you during the development cycle of your product to define the individual physical attributes suited to your specific application. Typical physical attributes may include raw material, viscosity, pH, conductivity, particle distribution and water content. In creation of these physical attributes, quality parameters will be developed to insure desired attributes are met.
WMFC Q_custom will allow you to tailor our product to your requirements.
Weidmann Fiber Technology is working with EMPA to commercialise the sponges.

Studies have shown increased flexural and impact strength, yielding a positive influence on crack suppression and general stabilisation characteristics.
– Increased cement flexural strength
– Controlled curing time
– Utilizes renewable material
Its high surface area-to-volume ratio, high strength, functionality, low environmental impact and sustainability make it the optimal base material for membranes for water filtration, contaminant adsorbents and further applications in filtering.
MFC provides a natural and sustainable raw material as an alternative to man-made materials.
