ElringKlinger Kunststofftechnik GmbH

What ElringKlinger Kunststofftechnik GmbH does

ElringKlinger Kunststofftechnik GmbH is a German specialty manufacturer of high-performance polymer components, headquartered in Bietigheim-Bissingen, Baden-Württemberg, and operating as a wholly-owned subsidiary of ElringKlinger AG. Founded approximately 60 years ago (circa 1964), the company develops and produces customized fluoropolymer-based parts — seals, guide rings, hoses, profiles, heat exchangers, and complete plastic assemblies — for demanding industrial applications. Its core technology platform rests on three proprietary material families: Polytetraflon®-PTFE, Moldflon® injection-moldable fluorothermoplastics (distinguished by their ability to be processed via injection molding for complex 3D geometries), and Elringplast, a PFAS-free high-performance compound portfolio addressing tightening regulation on per- and polyfluoroalkyl substances.

The company serves seven primary verticals: automotive and mobility (including electric drive and hydrogen powertrain), medical technology, the hydrogen economy (electrolysis, storage, transport), semiconductor manufacturing, chemical and process engineering, food and pharmaceutical processing, and general industrial manufacturing. Manufacturing is performed at the Bietigheim-Bissingen headquarters, the Heidenheim site (recently expanded in July 2026), and a new LEED-Gold certified facility in the Sino-German Ecopark, Qingdao, China, opened April 2026 with approximately 120 employees and quadruple the prior production capacity for Asian markets.

The business model is enterprise B2B, combining direct field sales for custom engineered solutions and assemblies (quote-based, multi-year contracts) with a self-service B2B online shop for standard and semi-standard products such as radial shaft seals, tubing, and semi-finished goods. Go-to-market is supported by active participation in industry trade shows (MedtecLIVE, ACHEMA, Auto Shanghai), technical content marketing, and a global representation network covering 19+ countries across EMEA, APAC, and the Americas. The company employs approximately 146 staff in Germany plus 120 in Qingdao as of 2026, and is led by Managing Directors Bo Sun and Marc Boos.
