What Heraeus Epurio does

Heraeus Epurio GmbH is a privately held specialty materials company headquartered in Leverkusen, Germany, and a wholly owned subsidiary of the Heraeus Group. It develops and manufactures the Clevios™ family of PEDOT:PSS conductive polymers — poly(3,4-ethylenedioxythiophene) complexed with polystyrene sulfonate — supplied as aqueous dispersions, solvent-based formulations, screen-printing pastes, and silver-nanowire hybrid inks. The Clevios™ chemistry spans conductivities up to ~1000 S/cm, sheet resistances from antistatic (10E10 Ohm/sq) to highly conductive (~15 Ohm/sq in HY E hybrid), tunable work function for OLED hole injection, and demonstrable flexibility exceeding 300,000 bend cycles at 1 mm radius.

The company sells directly to electronics, display, automotive, semiconductor, smart textile, and renewable-energy manufacturers through dedicated sales offices and technical service laboratories in Germany, the USA, China, South Korea, Taiwan, Japan, and Thailand. Primary applications are polymer aluminum/tantalum capacitors, OLED HIL layers, transparent electrodes and shielding for LCD/touch panels, smart-window films, antistatic/ESD protective coatings, conductive textiles, and hole-transport layers for organic and perovskite photovoltaics. Revenue is generated through quote-based B2B sales of formulated chemical products with no disclosed public pricing.

The business is undergoing a strategic refocus: in June 2026 Heraeus Epurio announced the sale of its semiconductor chemicals business line, including the Dayton, Ohio production site, to Brewer Science, concentrating future investment on the Clevios™ conductive polymer platform and emerging automotive smart-window, smart-textile, and perovskite solar applications.
