What Georg H. Luh does

Georg H. Luh GmbH is a German B2B wholesale supplier of specialty chemical raw materials, headquartered in Walluf and operating under family ownership since 1930. The company sources and distributes natural graphite, expandable graphite (Blähgraphit), mica (Glimmer), and related mineral-based raw materials, supplying industrial customers in fire protection, cable penetrations, conductivity, lubrication, and coatings. The customer base spans manufacturers of PU foams, plastics, textiles, and pipe collars, with no publicly disclosed named end-customers.

The product portfolio is built around custom-formulated raw-material solutions rather than off-the-shelf commodity supply. Core offerings include halogen-free flame retardants derived from expandable graphite, fire-protection systems, conductivity additives for conductive plastics and thermal-management applications, and graphite-based lubricants. Technical differentiation rests on proprietary formulation expertise and applications engineering across diverse end uses — from passive fire protection in construction to emerging New Energy segments such as fuel cells and redox-flow batteries. The HiPeX research partnership with LKT University Erlangen-Nuremberg (2024) signals continued R&D investment in high-performance expandable graphite.

Commercial activity is conducted through a direct enterprise field-sales model with project-based quotation and no reseller channel. Contracts may run multi-year, and pricing is not publicly disclosed. The company is privately held, has 11-50 employees, holds ISO 9001:2015 certification (2025-2028 cycle), and maintains no mobile app, public API, or social media presence. A Code of Conduct was published in January 2026.

Core offering

Georg H. LUH GmbH is a German wholesale supplier specializing in graphite and mica raw materials for industrial applications. The company provides expandable graphite, natural graphite, and mica, customized into application solutions for halogen-free flame retardancy, fire protection systems, thermal and electrical conductivity, and high-temperature lubricants serving manufacturers in plastics, polyurethane foam, coatings, textiles, construction, automotive, and renewable energy sectors.

Product overview

Georg H. LUH GmbH is a specialist for graphite and mica raw materials with over 90 years of experience, operating as a raw materials supplier in international wholesale trade. The company offers a portfolio of three core raw materials—Blähgraphit (expandable graphite), Naturgraphit (natural graphite), and Glimmer (mica)—which serve as the foundation for four main application areas: halogen-free flame retardancy, fire protection systems, conductivity solutions, and lubricants. These raw materials are customized and adapted for specific industry applications including polyurethane foam, plastics, textiles, coatings, pipe collars, cable penetrations, conductive plastics, thermal management, and new energy technologies such as fuel cells. The company positions itself at the intersection of traditional mineral expertise and modern industrial technology, serving sectors from construction and automotive to renewable energy.

Broad incumbents

• SGL Carbon: Germany-based global leader in carbon and graphite solutions, serving automotive, energy, industrial, and specialty applications. Comparable in product family (specialty graphite) and German industrial footprint, though operating at much larger scale and as a manufacturer rather than a trader.
• Imerys: French-headquartered global leader in specialty industrial minerals, with product lines spanning graphite, mica, and a broad portfolio of functional additives for plastics, coatings, and construction. Comparable as a large-scale incumbent in many of the same end-uses LUH serves, but with vastly broader scope.
• Nippon Carbon: Japanese producer of specialty graphite, carbon black, and related carbon products serving industrial markets. Comparable as a specialty graphite supplier into similar industrial applications, though focused on the Japanese and broader Asian markets.
• GrafTech International: US-based producer of graphite electrodes and engineered graphite products serving industrial customers globally. Comparable in its focus on specialty graphite products for industrial applications, but with a much larger manufacturing footprint and broader product line.
• Toyo Tanso: Japanese manufacturer of specialty graphite and carbon products serving semiconductor, industrial, and energy applications. Comparable in its focus on engineered graphite for industrial end-uses, though primarily a manufacturer serving Asia rather than a European trader.
• Minerals Technologies Inc. US-based specialty minerals company producing performance minerals and specialty graphite products for industrial applications. Comparable in supplying functional mineral additives to industrial customers, but at significantly larger scale and with broader end-market exposure.
• ALTANA AG: German specialty chemicals group focused on additives for coatings, plastics, and printing inks, including functional fillers and flame retardant solutions. Comparable in target customer base (plastics and coatings manufacturers in Europe) and as a German specialty chemicals platform, but with significantly broader product scope.
• AMG Critical Materials: Netherlands-based specialty materials company with graphite processing, vacuum furnace, and critical materials operations. Comparable because it supplies engineered graphite products into similar industrial verticals, although it is far larger and more vertically integrated than LUH.

Direct peers

• LKAB Minerals: Sweden-headquartered industrial minerals distributor within the LKAB group, supplying specialty minerals including graphite and mica into European industrial markets. Directly comparable in product mix (graphite, mica) and in operating model as a European specialty mineral trader.
• Asbury Carbons: US-based specialty graphite and carbon products supplier serving industrial customers with graphite powders, formulations, and application-specific grades. Highly comparable to LUH as a specialty graphite trader with custom formulation capability, although it is larger and US-focused.
