Welcome to Imerys Performance Minerals

FiberLean

FiberLean® Series

Imerys is the leading global producer of Micro-Fibrillated Cellulose (MFC) / mineral composites.

Imerys owns and operates four FiberLean® commercial on-site plants producing tailor made products delivering specific functionalities and cost efficiencies. 

Balancing the level and type of mineral with the level of MFC in the composite allows papermakers to enjoy a range of papermaking benefits including:

  • Lightweighting costly layers in multi-layer board
  • Reduction of market pulp
  • Improved strength characteristics
  • Opportunities for new product development

FiberLean® composite

FiberLean® MFC is a composite material produced by co-grinding cellulose fibers with minerals, whereby the minerals act as grinding media and make hydroxyl groups accessible. The MFC composite has a large surface area, which allows the formation of more hydrogen bonds within the web and gives natural strength to the paper. FiberLean® MFC grinding facilities can be installed at paper mills for tailor made products able to deliver significant value.

FiberLean® confers natural strength to the paper
