What Hoffmann Mineral does

HOFFMANN MINERAL GmbH is a privately held German specialty mineral filler manufacturer headquartered in Neuburg an der Donau, Bavaria. The company is registered under German trade register HRB 5264 with Managing Director Manfred Hoffmann and is part of the wider family-owned "companies Hoffmann" group; founded in 1903, it operates as a single-site producer with 11–50 employees. Its core technology is the extraction and processing of Neuburg Siliceous Earth (NSE) — a geologically unique natural combination of corpuscular silica and lamellar kaolinite from a single deposit — followed by calcination, classification, and surface functionalization. This produces five principal product families: Sillitin (standard untreated grades), Silfit Z 91 (calcined, high brightness), Aktisil (surface-treated), Aktifit (calcined and surface-treated), and the Gloxil family (tailored filler solutions including Gloxil bright/light/matt/WW SL). Gloxil light is co-developed with 3M using hollow glass microspheres and supports lightweighting in polyamides, polypropylene, and FKM elastomers.

The portfolio targets functional performance in industrial formulations, including partial replacement of carbon black (more than 50% substitution demonstrated in EPDM car body seals) and titanium dioxide (across interior emulsion, coil coating, 2C PU top coat, road marking, powder coatings, and polystyrene), dielectrical performance for cable insulation, anti-blocking and IR absorption in films, matting and rheology control in coatings, and abrasion resistance/cleanability in elastomers. Customer segments are organized vertically across Elastomers, Thermoplastics/TPE, Paints & Varnishes, Reactive Resins/Adhesives/Sealants, and Polishing/Cleaning Agents plus dental, cosmetics, plant protection, and welding. The company holds ISO 9001/14001/45001/50001 certifications, a TÜV Rheinland-conducted Life Cycle Assessment under ISO 14040:2021 and 14044:2021, REACh compliance statements, and a NATRUE certificate for Sillitin via the Xatico Group.

Revenue mechanics are B2B industrial sales with a quote-based, order-by-order pricing model rather than subscription or licensing, complemented by contract Toll Manufacturing services covering mixing/homogenizing, surface modification, and re-packaging into silos up to 25 t, big bags, paper/PE/EVA bags. Go-to-market combines direct enterprise sales via website contact/sample-order/login-portal, an international distributor network (Carst Walker for Australia since Feb 2026, Austral for Chile since May 2026, Xatico Benelux-France Sàrl for France/Benelux), event-driven demand generation (Fakuma 2024, Conférence de la Plasturgie), and content marketing via a large technical documentation library and LinkedIn Spotlights. Pricing is not publicly disclosed, revenue is not reported, and the company has no disclosed funding rounds or M&A activity.

Revenue model

1. Sale of mineral filler products: Core revenue from selling functional filler products (Sillitin, Silfit, Aktisil, Aktifit, Gloxil, and Tailored Filler Solutions grades) to industrial formulators. Sales are order-based via website sample ordering and contact form; not a recurring subscription.
2. Toll Manufacturing Services: Contract-based revenue from toll manufacturing services including mixing and homogenizing, surface modification, and re-packaging into silo (up to 25 t), big bag (200–900 kg), paper bag (10–25 kg), PE bag and EVA bag containers.

Core offering

HOFFMANN MINERAL GmbH manufactures and sells functional mineral fillers based on Neuburg Siliceous Earth, a natural single-deposit combination of corpuscular silica and lamellar kaolinite. The portfolio spans Sillitin and Sillitin puriss standard grades, calcined Silfit Z 91, surface-treated Aktisil, calcined-and-functionalized Aktifit, and the Tailored Filler Solutions platform (Gloxil bright, Gloxil light with 3M glass bubbles, Gloxil matt). The company also offers contract toll manufacturing services covering mixing, surface modification, and repackaging into silo, big bag, paper bag, PE bag, and EVA bag containers.

Product overview

Hoffmann Mineral operates a single integrated product portfolio centered on functional mineral fillers based on Neuburg Siliceous Earth, rather than a modular software platform. The portfolio is organized into two main product lines: (1) Neuburg Siliceous Earth, which encompasses the natural Sillitin and Sillitin puriss grades, the calcined Silfit Z 91, the surface-treated Aktisil line, and the calcined-and-functionalized Aktifit line; and (2) Tailored Filler Solutions, a customer-specific offering built around the Gloxil bright (thermally treated aluminum silicate), Gloxil light (functionalized hollow glass microspheres co-developed with 3M), Gloxil matt (silica gel-based matting agents) and related variants such as Gloxil WW SL. Alongside these branded products, the company offers Toll Manufacturing services covering mixing, surface treatment and re-packaging, supported by technical documentation (data sheets, safety data sheets, material specifications, technical posters and reports) across the industries of elastomers, thermoplastics, TPE, paints and varnishes, reactive resins, adhesives, sealants, polishing/cleaning agents and other industries including dental care and cosmetics.
