Walki®Re-inforce / Walki®EasySeal
Thermoformable automotive skins that do more with less
High-performance, lightweight and recyclable materials for underbody shields, carpets and interior components
Walki solutions for automotive materials
Lightweight, high-performance materials designed for efficiency and circularity
Walki develops advanced material solutions for automotive applications where performance, weight and sustainability must work together. Our portfolio includes thermoformable skins and engineered materials designed to deliver adhesion, reinforcement, acoustic insulation and barrier protection across a wide range of components.
From underbody systems to interior applications such as carpets, headliners and load floors, Walki materials help reduce complexity, optimise production and support design for recycling. By combining multiple functionalities into fewer layers, we enable more efficient manufacturing and improved material use throughout the vehicle lifecycle.


Thermoformable materials for automotive
Thermoformable skins are advanced multilayer or mono-material structures that can be shaped under heat and pressure into complex automotive components.
They act as functional layers within composite parts, delivering multiple benefits:
- Structural reinforcement
- Adhesion between layers
- Acoustic insulation
- Barrier protection (moisture, gas, chemicals)
Unlike traditional solutions requiring multiple materials and process steps, Walki skins integrate functionalities into a single solution, improving efficiency across the value chain.

| Feature | Walki®Re-inforce | WALKI®EasySeal |
|---|---|---|
| Primary use | Underbody shield reinforcement | Car carpet backing and adhesion |
| Key function | Tear resistance, structural integrity | Strong bonding between carpet layers |
| Mechanical strength | High | Moderate |
| Acoustic role | Secondary | Primary (noise and vibration damping) |
| Barrier performance | Limited | Moisture, gas and chemical barrier |
| Exposure | External (harsh conditions) | Interior environment |
| Mono-material availability | Yes (Re-inforce Mono) | Yes (EasySeal Mono) |
| Added value | Reinforces durability of components | Combines adhesion, barrier and acoustics |
Reducing complexity. Enabling circularity.

Designing materials for a circular EV future
Why recyclability, lightweighting and fire safety matter more than ever
As demand for battery materials grows, improving the recyclability of all vehicle components becomes critical. Walki is helping drive this change with materials that are lighter, recyclable and engineered for fire safety. Learn how smarter material design contributes to energy efficiency, safer vehicles and a more sustainable automotive ecosystem.
They are engineered materials that can be heat-shaped into automotive components while providing structural, acoustic and barrier functions.
Mono-material structures improve recyclability and support circular automotive design.
Typical applications include underbody shields, carpets, headliners, wheel arch liners and trunk load floors.
By combining multiple functions into one layer, reducing process steps and simplifying handling.
Yes. Lightweight, acoustic and fire-related performance make them highly relevant for EV requirements.
