ADDEV Materials designs and converts high-performance films, adhesives, tapes and insulating materials for EV batteries, energy storage, aerospace, healthcare and electronics. The company emphasizes custom conversions, thermal and electrical insulation, EMI shielding and eco-design.
ADDEV Materials, founded in 2006 and headquartered in Lyon, France, was created by Pascal Nadobny and Julien Duvanel. The company designs, converts, distributes and manufactures high-performance, customized material solutions for aerospace, mobility, healthcare, energy and electronics sectors. Its stated purpose is converting industrial challenges into sustainable materials solutions. ADDEV combines global manufacturing capabilities with localized services to support clients’ ecological and energy transitions while reducing waste and logistics impact.
ADDEV Materials focuses on conversion and functionalization technologies: precision slitting, sheeting, lamination, printing, formulation and custom dosing systems. Core offerings include electrical and thermal insulation films (Kapton®, Nomex® equivalents), ultra-thin heating films for battery thermal management, EMI shielding layers, fire-protection foams and high-performance adhesives and sealants. Differentiators are multi-material integration, co-development via ADDEV Tech, and partnerships with producers such as DuPont and 3M to develop lower-impact formulations and recyclable assemblies. Eco-design and compliance with aerospace and automotive standards are integral to performance and safety benefits.
Product lines include chemical solutions (adhesives, solvents, surface treatments), adhesive tapes and foams, technical films and laminates, insulating papers and flexible protective materials. These are applied across EV batteries, stationary energy storage, fuel cells, aerospace MRO, medical devices, electronics and industrial assemblies to improve electrical insulation, thermal management, sealing and mechanical protection.
Recent initiatives (2024–2025) include the ATL Corp acquisition (2024) to expand converting capacity and geographic reach; an internal Innovation Hackathon (2025) that produced prototype materials and co-development leads for battery applications; and the EcoVadis Platinum recognition (2025, score 82/100) reflecting strengthened sustainability practices and supplier engagement in support of market expansion in North America (2025).
ADDEV’s ownership history includes early investors such as Société Générale Capital Partenaires, Naxicap and Garibaldi Participations alongside founder stake retention. In 2019 Tikehau Capital and Bpifrance acquired a minority stake for €38 million to support international expansion. In 2025 Naxicap Partners entered exclusive negotiations to acquire a majority stake, while founders and management continue to hold significant shares.
