finexus® fields of application
finexus® is a nonwoven solution for interior and exterior components across the entire mobility sector:
Dirt, rocks, ice and other environmental factors cause corrosion. finexus® protects the underbody with its high resistance against environmental influences. Simultaneously, its flexible formability supports aerodynamics and improves noise protection as well as thermal insulation. A single polymer material, finexus® is characterized by an optimal ratio between flexibility and strength, thereby facilitating both the installation in vehicles and ensuring the performance during use.
Specifically for parcel shelf use, finexus® is available in higher basis weights. With its high definition, even curvatures and complex geometries are possible. Being 100% polyester, finexus® does not release harmful substances.
Wheel arch liners made from finexus® score points for the protection against mechanical damage as well as for the reduction in weight compared to plastic liners. An acoustic absorber itself, finexus® reduces the number of additional absorbers, helps to reduce wheel and driving noise, and supports snug fitting geometries.
finexus® headliner boards impress with acoustic efficiency and easy assembly. Using special fibers, this 100% polyester material withstands higher temperatures in vehicle interiors. finexus® is flexibly moldable and allows for the integration of various components. Trimming and die-cutting remnants can be recycled for new products.
finexus® proves being a hard-wearing material in trunk liners, a material that withstands impacts and is easy to clean given its water-repellent surface. In processing, finexus® can adjust to the most various geometries and, at the end of its life cycle, can easily be recycled.
Thanks to its stability and smooth surface, finexus® is an ideal material for frunks, creating additional stowage space in the vehicle. The nonwoven fabric combines dimensional stability with sound-absorbing properties. In addition, the material is notable for its light weight.
Given its self-supporting nature and its highly bonded surface, finexus® is ideally suited for trays and liners in storage compartments. Its hydrophobic properties provide excellent protection against environmental impact and its flexibility lets it adapt also to complex geometries.
finexus® offers a multitude of possible applications in truck cabin interiors. For side panels, rear wall panels or headliners – Sandler’s innovative 100% polyester material provides for the rigidity needed for dimensionally stable components. finexus® is acoustically effective and has been tested for harmful emissions in accordance with VDA 277; the results are available in the data sheet.
finexus® is excellently suited for underbody applications in commercial vehicles. Its highly bonded surface forms an effective barrier against stone chipping, dirt and other environmental influences. Thanks to the hydrophobic nature of the material, it requires no additional protective layers, also meaning that the purity of the material is maintained. In addition to its high stability when used as a molded component, finexus® also contributes to the damping of tire and rolling noise in the underbody area.
Proven Sustainability
Our technology allows us to incorporate at least 10% recycled fibers into our product. For finexus®, the GWP is 0.953 kg CO2e/kg, calculated in accordance with DIN EN ISO 14040, 14044, and 14067 within the cradle-to-gate system boundaries for the 2023 reporting year. Both the final product molded from our nonwoven fabric and the residual raw materials generated during production can be technically evaluated for reprocessing.
Cooperating with fiber suppliers and research institutes, we are working to develop recycling processes for the production of novel fibers and products based on recycled content.

Processing Properties of finexus®
The processing properties of finexus® are characterized by the rigidity and the specific properties it obtains during the thermo-forming process in which the cold nonwoven is placed in a mold heated to 190°C/ 374°F. Pressure and this ideal temperature activate the fibers and make them assume the intended geometry. Subsequently, the material needs to be cooled, ideally using a fixed cooler or a tentering frame to achieve accurate contours. Further processing may include water jet cutting, embossing or pinching in the tool.

Mobility requires materials that go the extra mile.
finexus® combines acoustics and thermal insulation in a single material made of 100% PET. Depending on the fiber blends, up to 80% recycled fibers can be incorporated. Its recyclability and potential for circular use make this material a concrete example from the “Product” action area.
