What Krempel does

Krempel GmbH is a privately held German specialty materials manufacturer founded circa 1870 and headquartered in Vaihingen an der Enz, with 1,001–5,000 employees and operations across 12 sites in 8 countries (Germany, USA, UK, Mexico, Brazil, Croatia, Austria, China). The company designs and manufactures electrical insulation materials, composites, flexible base materials and thermal insulation products, organised around three end-markets — Energy (motors, generators, liquid and dry transformers, wind and solar), Mobility (automotive, railway, aerospace) and Industry (protection technology, healthcare, mechanical engineering, construction). Its portfolio spans presspaper and pressboard, mica products, Kapton films, epoxy resin systems, prepregs, Tedlar films, organosheets, moulded composite parts (radomes, nozzle insulations, precision bearing cages, composite tubes, pultrusion profiles), sleevings/textiles and thermal insulation.

The company's technical core is proprietary material chemistry and qualified composite engineering, evidenced by registered brand families such as TRIVOLTHERM E-Fluid-Safe (insulation laminate for liquid-cooled electric motors), KremGuard (FST-rated epoxy prepreg system), KremSol Repair (sustainable PV backsheet repair solution), VIDAFLEX Fire-Sleeve and Phenolic Resin Systems. Krempel also holds an exclusive DuPont licence to manufacture and sell Nomex 910 aramid-enhanced cellulose paper. It is one of the top five players in the global Mica Tape for Electric Insulation market.

Krempel generates revenue primarily through B2B direct/field sales of engineered materials and components to enterprise customers, distributed across Europe, the Americas and Asia. Pricing is negotiated on a per-contract basis with no public disclosure. Recent strategic actions — the September 2024 acquisition of Mexico-based EIC Insulation Company, the December 2024 opening of a Slitting and Logistics Centre in Croatia, and a sequenced product-launch cadence through 2023–2025 — point to active expansion of geographic reach, EV/solar adjacencies and aerospace fire-safety capabilities.
