Without controlled insulation and optimum heat management, no machine, no energy distribution network and no electric mobility solution could operate safely and sustainably.
Whether it's high, medium or low voltage transformers, industrial motors, batteries for electric mobility and stationary or industrial applications, or cables for intelligent buildings, the combination of high-performance insulation and efficient thermal management determines the longevity and reliability of systems.
ADDEV Materials has established itself as a benchmark partner for manufacturers looking for reliable, innovative and durable high added-value solutions to protect, insulate and optimise the performance of their equipment.

FAQ - Electrical insulation, performance and thermal management
Electrical insulation prevents current from escaping, protects users and avoids short circuits. It is essential to guarantee the safety, performance and longevity of equipment.
We offer a complete range of materials: Nomex®, Kapton®, mica tapes, PET films, fibres, non-wovens, technical and cellulose papers, resins, sheaths and tubes. Each application requires the right combination to guarantee safety and performance.
The rotor (the moving part of a motor) and the stator (the fixed part) are subject to different mechanical, thermal and electrical stresses. We provide specific solutions for each, capable of withstanding vibrations and high temperatures.
Our solutions are designed with eco-design in mind. We favour recyclable materials and optimised processes, and we use our LEA tool to measure and reduce the carbon impact of each project.
Absolutely. We co-develop specific solutions with our customers, from the prototyping phase through to series production, to meet precise and complex requirements.
