Rühl

What Rühl does

Rühl Gruppe is a privately held, owner-managed German chemical and diversified-services group headquartered in Friedrichsdorf near Frankfurt, with origins dating to 1948. The group operates through three main entities: Rühl Puromer GmbH, one of the leading independent polyurethane (PU) systems suppliers in Central Europe with more than 50 years of formulation experience; Rühl AG & Co. Chemische Fabrik KG, a contract manufacturer specializing in cleaning and disinfection products, notably peracetic-acid disinfectants at concentrations between 2.5% and 15%; and Rühl Immobilienentwicklungs GmbH, a real estate developer focused on commercial properties and energy-efficient apartments in Friedrichsdorf. The group employs approximately 100 people and is led by owner Andreas Rühl alongside co-managing director Johann Heyken and Puromer managing director Dr. Ingo Kleba.

The core technology platform is Rühl Puromer's polyurethane systems house, which develops and produces custom-made PU formulations across ten branded product families — puroflex, purotherm, purodur, puropreg, purocast, purorim, puroclear, puroskin, and purovib — covering integral skin foams, flexible foams, rigid foams, fibre composites (including LFI honeycomb), RIM systems, self-healing coatings, cast elastomers, and high-performance elastomers. Production is direct from Friedrichsdorf with batch sizes ranging from 50 kg to 20,000 kg, and the company operates under ISO 9001:2015 (since 1997) plus EN ISO 13485:2016 and GMP-qualified filling systems for the medical-device disinfectant line. PU formulations are sold into automotive OEMs (BMW, Audi, Mercedes-Benz for surface coatings, structural composites, and steering-wheel/interior trim), construction, furniture, and medical applications.

Go-to-market is sales-led and direct: technical advice, application engineering, development, and production are delivered under a single-source service model from product idea to serial production, supported by sales offices in Taicang, China and near Detroit, North America. Revenue is generated through quote-based B2B pricing on custom-formulated chemical batches (one-time license-style sales), per-batch contract manufacturing fees for disinfectants, and project-based real estate development — with no public pricing and no disclosed revenue figures.
