About Freudenberg FST GmbH
Freudenberg FST GmbH (formerly Trygonal Group GmbH, part of the Freudenberg Group since 01.11.2024) develops and manufactures sealing technology and polymer solutions from a single source. The portfolio includes seals and O-rings (inner diameter less than 1 mm to outer diameter 2,500 mm), rubber molded parts, plastic turned and milled parts as well as polyurethane molded and foam parts. Production takes place from our own semi-finished products based on polyurethane and rubber compounds, which are continuously further developed in cooperation with industry partners and universities; this is complemented by CNC lathes, 5-axis machining centers and injection molding machines, from machined prototype to injection-molded series part. The compounds are tested by recognized institutes for approvals such as FDA, KTW, W270, 3A-sanitary, EU 1935/2004 and EU 10/2011. Customer industries include heating technology, valve technology, mechanical engineering, chemical/pharmaceutical, hydraulics/pneumatics, medical technology, automotive, water treatment, food, aerospace and rail transport. The headquarters is located in Sachsenheim-Ochsenbach; further sites exist in Germany, Austria, Switzerland and Spain.
