About ElringKlinger Engineered Plastics
ElringKlinger Kunststofftechnik GmbH (ElringKlinger Engineered Plastics) is a globally active manufacturer of technical components made from high-performance plastics with headquarters in Bietigheim-Bissingen. The company manufactures sealing systems, bellows, diaphragms, hoses and profiles, heat exchangers, precision parts as well as semi-finished products from materials such as Polytetraflon™-PTFE, Moldflon™ fluorothermoplastics (PFA, FEP, ETFE, PVDF, PCTFE) as well as fluorine-free Elringplast materials (PEEK, PPS, PPSU, PE-UHMW). The value chain ranges from in-house material development and compounding through the production of semi-finished products to the finished component. Processes include injection molding, extrusion, pressing and sintering of PTFE, machining (turning and milling to drawing) up to cleanroom production according to ISO Class 8 for medical technology as well as oxygen cleaning according to ASTM G93. Customers come from automotive and mobility, aerospace, chemical and process engineering, energy and hydrogen, oil and gas, semiconductor industry, fluid technology, food and pharma, life sciences as well as mechanical engineering. The company employs over 750 staff at five locations on three continents and generated revenue of €144.5 million in 2025.
