About Hoffmann + Voss
Hoffmann u. Voss GmbH is a company based in Viersen in the Rhineland that has been active in the market since 1962, supplying raw materials to the plastics industry. The focus is on the compounding of engineering thermoplastics: recompounds, recyclates and individually formulated compounds are produced tailor-made to customer requirements, including additive modification, color variations and material modifications. The portfolio includes its own material families based on polycarbonate (Dylex PC), ABS (Dylac), PA 6 and PA 66 (Dymid), PBT (Dylox), PP (Dycom) as well as numerous blends such as PC+ABS, PC+ASA, PC+PBT and PC+PET. Recycling and reuse shape all phases of the production processes. Quality assurance takes place in a 24/7 laboratory with infrared spectroscopy and X-ray fluorescence analysis; every material undergoes three quality inspections before delivery (incoming goods inspection, production-accompanying inspection, final release inspection). The materials are used across industries, including in plastics processing and automotive manufacturing, where hardly a premium vehicle exists without a material from the Hoffmann + Voss house. Since 2025 the company has been part of the PolymerCycle Group, an integrated plastics recycling group. The company headquarters and production are located at Textilstraße 3-5 in Viersen.
