KERAFOL is a family-owned German maker of thermal interface materials and technical ceramics. Its products — films, gap pads, molding compounds, graphite foils and ceramic substrates — serve EV battery packs, power electronics, stationary storage and filtration systems.
KERAFOL produces thermally conductive films, gap pads, molding compounds and ceramic tapes using tape casting, injection molding and sintering. Core technologies include electrically insulating but thermally conductive films (KERATHERM), thermally conductive molding compounds (KERAMOLD), graphite foils for heat spreading, and thin zirconia electrolyte substrates for SOFCs. Supporting capabilities such as dispensing, screen printing, laser cutting and prototype sintering enable customer-specific geometries and reliable interfaces. Benefits include improved heat dissipation, reduced hotspot formation, electrical isolation where required, and materials choices that support safer battery systems and easier module servicing. KERAFOL supports the battery ecosystem by supplying thermal interface materials, ceramic and polymer-based solutions, and application services that help batteries, BMS, power electronics, charging systems, and energy storage systems operate more safely, efficiently, and reliably.
The portfolio covers thermal interface materials (gap pads, gap fillers, pastes, adhesives, thermally conductive films), thermally conductive injection molding compounds, graphite foils, ceramic tapes and SOFC components, plus porous filter ceramics. Products are used in EV battery packs, power electronics, stationary energy storage, industrial electronics, consumer devices, medical and environmental filtration applications to manage temperature, protect components and extend service life.
KERAFOL remains a family-managed company; Sabine Koppe and Isabell Koppe are identified as a shareholder within the holding structure. No external equity investors or public funding rounds are disclosed in the available information.
