What Fluorochemistry Stulln does

Fluorchemie Stulln GmbH is a German specialty chemicals manufacturer headquartered in Stulln, Bavaria, that has produced hydrofluoric acid (HF/Flusssäure) at the same site since 1940. The company is part of the privately held Fluorchemie Group and operates one of the most modern hydrofluoric acid production facilities in Europe, erected by VAW Flussspat-Chemie GmbH in 1982/83 and continuously upgraded since. Its product portfolio comprises hydrofluoric acid (liquefied gas and aqueous solutions), calcium sulfate binder (EN 13 454-1 CAB 30) used in screeds for underfloor heating systems, hexafluorosilicic acid for aluminum fluoride and cryolite production, and acid-grade fluorite (≥97% CaF₂) as the upstream raw material. HF is produced via reaction of acid-grade fluorspar with sulfuric acid, releasing hydrogen fluoride gas, with energy and quality management as central operational priorities.

The business model is industrial B2B direct sales with no e-commerce or digital channel; pricing is quote-based and undisclosed publicly, structured as multi-year agreements. The Fluorchemie Group operates a fully vertical value chain from the Phönix fluorspar and barite mine near Ilmenau in Thuringia, through Mitteldeutsche Fluorit GmbH processing, to HF production at Stulln and Dohna, which secures raw material supply against world market volatility. The company is ISO 9001:2015 (quality) and ISO 50001:2018 (energy management) certified and operates under the German Störfall-Verordnung (12. BImSchV) for hazardous installations. Customers span industrial manufacturers across aluminum smelting, chemical processing, construction materials, automotive (aluminum wheel cleaning), glass treatment, and consumer products (fluoride toothpaste additives). Following the 2021 acquisition by Thanatos Chemical Industries GmbH and Fluorchemie Kronberg GmbH, the group has signaled a strategic pivot toward electric-mobility distribution channels and sustainable local raw material sourcing.

Revenue model

1. Hydrofluoric Acid (HF) Sales: Production and sale of hydrofluoric acid (Flusssäure), the core product. Applications include aluminum wheel cleaning, stainless steel decontamination, weather-resistant plastic fibers, glass treatment, and toothpaste additives. Sold as liquefied gas or aqueous hydrofluoric acid solution.
2. Calcium Sulfate Binder Sales: Production and sale of calcium sulfate binder (Calciumsulfatbinder EN 13 454-1 CAB 30) used in screeds, flowing screeds, putty, and plasters. Self-leveling, quick-setting properties with lower shrinkage and thermal expansion compared to cement. Ideal for in-floor heating applications.
3. Hexafluorosilicic Acid Sales: Production and sale of hexafluorosilicic acid (Fluosilic Acid), primarily used in production of cryolite and aluminium fluoride for the aluminum industry.

Core offering

Fluorchemie Stulln GmbH manufactures hydrofluoric acid (HF/Flusssäure) and hexafluorosilicic acid through reaction of acid-grade fluorspar with sulfuric acid at its Stulln facility, one of the most modern HF plants in Europe. The company also produces calcium sulfate binder (EN 13 454-1 CAB 30) used in screeds and floor-heating construction applications. Products are sold in bulk (liquefied HF gas or aqueous solutions) directly to industrial customers in aluminum smelting, stainless steel processing, glass treatment, automotive, construction, and consumer products sectors.

Product overview

Fluorchemie Stulln GmbH operates as a specialty chemicals manufacturer focused on fluorine chemistry and calcium sulphate binders. The company is part of the Fluorchemie Group and operates one of the most modern hydrofluoric acid production facilities in Europe, producing since 1940. The product portfolio centers on four main offerings: Hydrofluoric Acid (the core product serving as a fundamental chemical for aluminum manufacturing, plastic fibers, glass treatment, and dental products), Calcium Sulphate Binder (used for screeds and flowing screeds with floor heating applications), Hexafluorosilicic Acid (used in cryolite and aluminum fluoride production for the aluminum industry), and Acid Grade Fluorite (raw material with 97% CaF2 content serving as the base input for hydrofluoric acid production). The group maintains a complete value chain from fluorspar mining through to fluorine chemical products.

Functional benefit

Products and services

• Hydrofluoric Acid (Flusssäure/HF) Hydrofluoric acid (HF) is a foundational chemical supplied in liquefied gas or aqueous solution form to industrial manufacturers across aluminum smelting, stainless steel decontamination, weather-resistant plastic fibers, glass treatment, automotive aluminum wheel cleaning, and toothpaste additive applications.
• Calcium Sulphate Binder (Calciumsulfatbinder EN 13 454-1 CAB 30) Calcium sulphate binder used primarily in screeds, flowing screeds, putty, and plasters, offering easy application, self-leveling properties, quick setting, lower degradation tendency than cement, and low thermal expansion suitable for in-floor heating applications.
• Hexafluorosilicic Acid (Fluosilic Acid) Hexafluorosilicic acid produced at Stulln, used primarily in the production of cryolite and aluminum fluoride for the aluminum industry.
• Acid Grade Fluorite (Säurespat, 97% CaF2) Acid-grade fluorite with minimum 97% calcium fluoride content, excavated through mining/quarrying with impurities removed to achieve required purity; serves as the base raw material for hydrofluoric acid production across the Fluorchemie Group value chain.

Quantifiable outcome

• Global fluorite consumption is approximately 4.5 million tonnes per year, with acid-grade fluorite production capacity exceeding 3 million tonnes
