don't 15 industrialists
The sector railway imposes high constraints in terms of security, durability, fire/smoke compliance and long-term reliability. In this context, manufacturers and equipment suppliers need material solutions capable of meeting strict technical requirements, particularly for electrical insulation, thermal management, assembly, sealing and vibration reduction.
ADDEV Materials supports stakeholders in the railway with a comprehensive approach: material selection, bespoke conversion, technical support, and industrialisation. Our solutions cover the main environments of rolling stock and its ecosystem, including the carbody, the cab interior, electrical systems, signalling, and infrastructure. The proposed solutions meet market demands, particularly standards EN 45545 applicable to rolling stock and its environment.

Addressing the main technical challenges in the railway industry
The industrialists of railway must reconcile safety, performance, and cost control. Furthermore, they must incorporate materials capable of lasting over time, while respecting the regulatory and operational constraints of the sector.
Fire safety and compliance
Materials must meet market requirements, particularly regarding fire reaction, smoke, and passenger safety. Compliance with EN 45545 is therefore a key criterion in many rail applications.
Electrical isolation and system protection
On-board equipment, traction motors, converters and transformers require reliable insulation solutions to ensure safe electrical performance.
Thermal management and sustainability
Furthermore, the increasing presence of onboard electronics, HVAC systems, and power functions necessitates improved thermal management. Materials must therefore help protect components, limit hot spots, and guarantee the lifespan of equipment.
Reduction of vibrations, noise and wear
Finally, passenger comfort, mechanical integrity and maintenance depend heavily on the ability of materials to absorb vibration, friction and noise.
Carbody and external structure
We can help you with all your needs relating to :
- surface protection,
- environmental resistance,
- to assembly
- the mechanical strength of the structure.
Cabin interior and flooring
The needs here concern :
- assembling the interior components,
- watertightness,
- acoustic comfort,
- branding,
- fixing coverings such as technical floors, linoleum or safety zones.
Electrical systems and traction
Le railway is based on systems that are subject to heavy stress:
- traction motors,
- converters,
- transformers,
- wiring,
- on-board electronics.
These applications require high-performance materials for :
- electrical insulation,
- mechanical protection
- thermal management.
HVAC and thermal management
HVAC systems require both :
- sealing,
- isolation,
- vibration damping
- thermal performance.
Several families of foams, films and sealing materials are used in these areas.
Signalling, maintenance and infrastructure
Le railway is not limited to the train itself. Infrastructure, signalling, overall maintenance and marking areas also require reliable and durable technical materials.
Where do our solutions come into play in the rail industry?
ADDEV Materials supports industrial manufacturers with all critical sub-assemblies for railway.
Addressing the main technical challenges in the railway industry
The industrialists of railway must reconcile safety, performance, and cost control. Furthermore, they must incorporate materials capable of lasting over time, while respecting the regulatory and operational constraints of the sector.
Electrical insulation
Technical films, laminates, insulating papers, composites, sheaths, tubes and resins protect traction systems, transformers, converters and on-board electrical equipment.
Thermal management
Thermal management solutions are used for on-board electronics, HVAC systems, walls and other critical areas of the train.
Assembly and fixing
Depending on requirements, we offer assembly solutions for cabin furniture, interior parts, signage elements or technical sub-assemblies.
Watertightness
Sealing requirements include HVAC systems, interiors, certain types of lighting and various interfaces subject to humidity, dust or vibration.
Surface protection
Le railway involves a large number of exposed areas: exterior surfaces, glazing, maintenance areas and highly stressed interior components. Protection and coating solutions can improve the durability of these components.
Vibration reduction
Solutions NVH are particularly useful for traction motors, walls, floors, roofs, doors or HVAC systems.
Marking and signage
Marking, safety labels, floor markings and digital or non-digital signage are also a recurring market need.
What materials are needed for railway applications?
ADDEV Materials offers a wide range of high-performance materials for the railway.
Flexible materials
- technical films, laminates and papers
- technical foams
- certain protection and insulation solutions
These materials are used for electrical insulation, surface protection, assembly, sealing, thermal management and vibration reduction.
Rigid materials
Composites, ducts and tubes provide mechanical protection, fixing, insulation and robustness in the most demanding environments.
Liquid materials
Resins, varnishes, sealants, adhesives and protection solutions complete the range for assembly, impregnation, sealing and electrical protection applications.

ADDEV can support your project in several stages
1. Needs analysis
Understanding of the application, environment, regulatory constraints and volumes.
2. Material and process selection
Choosing the right product family and processing method.
3. Prototyping and validation
Production of samples or prototypes to de-risk the solution.
4. Pre-industrialisation and production
Document validation, process optimisation and series launch.
What is the right material for your rail application?
The right choice generally depends on four criteria:
1. Usage environment
- Temperature
- Humidity
- Vibrations
- Chemical exhibition
- Fire/smoke constraints
2. Function required
- Electrical insulation
- Waterproofing
- Surface protection
- Noise reduction
- Assembly
- Marking.
3. Expected level of compliance
Certain applications require a stricter approach to regulatory requirements and fire performance.
4. Industrial integration
The material must also be compatible with your process, your pace and your logistical constraints.
FAQ – Rail Market
Railway applications notably use technical films, laminates, insulating papers, foams, composites, sheaths, resins, adhesives, and surface protection solutions. These families are clearly evident in the ADDEV supports dedicated to the market.
The EN 45545 standard governs the fire/smoke requirements for materials used in railway. It constitutes a key benchmark for industry players in the sector.
The most common solutions include technical films, insulating papers, composites, sheaths and resins, depending on the area concerned: transformers, converters, traction motors or onboard electrical systems.
Technical foams, damping materials and NVH solutions help to reduce vibrations, friction and noise on walls, floors, roofs, doors, engines or HVAC systems.
