About STW-Faser
STW-Faser manufactures technical fibers and derived products: a comprehensive standard program of fiber fillers, short-cut fibers and fibrides (pulp), as well as custom fiber solutions tailored to customer specifications. Using in-house developed production processes, nearly all raw materials are processed — from aramid and synthetic fibers to mineral fibers and cellulose fiber. To develop customer-specific solutions, the company conducts targeted test projects and trial series; a sample box containing numerous raw material samples supports the selection process. The fibers are used in a wide range of applications, including the composites industry, the construction industry, and the coatings and paint industry. Its presence at international trade fairs such as JEC World, Big 5 Global and the European Coatings Show demonstrates its international customer base.
