22 Kelheim Fibres: Competence in Paper In our in-house technical centre we run amongst others - a pilot machine with inclined wire technology. This delivers: A clear understanding of our customers production processes and products The capability to test our products, their further processing properties and the properties of the papers produced. The possibility for our customers to run trials with our fibers without the need to interrupt commercial production. 22

23 In Conclusion. Kelheim Fibres is the world s leading expert in the science of specialty viscose rayon fibers production. Viscose rayon fibers are made from wood pulp, but offer homogenous and consistent quality 365/365 days. Cross section, dimensions and functionality of viscose rayon fibers can be modified. Viscose rayon fibers are a versatile tool for the control of paper properties. What is the difference between cellulose and cellulose? Specialtiy Viscose Rayon fibers from Kelheim Fibres. 23
