Freudenberg Performance Materials and Japan Vilene Group will present solutions for energy, medical and automotive markets at ANEX. The broad product spectrum ranges from battery separators and laminates comprising hydrophilic PU foams and hydroactive nonwovens to acoustic pads for vehicles.

Redox flow batteries are in demand wherever large amounts of energy need to be stored over several hours while remaining ready for discharge at any time. A key aspect is optimizing efficiency. Freudenberg’s nonwoven electrodes with a unique three-dimensional fiber structure were specially developed to improve liquid circulation in redox flow batteries. These innovative electrodes feature a flexible design that enables them to be adapted to specific customer requirements.

One key to the success of e-mobility is providing more efficient and safer batteries. Freudenberg’s safety separator for lithium-ion batteries consists of an ultra-thin PET nonwoven impregnated with ceramic particles. It remains stable at high temperatures and does not shrink and is considerably less sensitive to mechanical penetration.

Following the introduction of an MDI-based foam, Freudenberg Performance Materials has continued with the systematic expansion of its portfolio in this field. The company hasnow enteredseries production ofISO 13485-compliantlaminates comprising hydrophilic PU foams and hydroactive nonwovens. The combination of these two components, foam and nonwoven, can achieve a significant improvement in the abilityof wound dressings to absorb and retain exudate. Customers can choose between MDI- and TDI-based foams.

“scaffolene” – Freudenberg’s nonwoven fabric madefrom bioresorbable polymers is extremely versatile in both characteristics and applications. Flexible and tear-resistant when dry, it remains stable even when wet, maintaining its structure and avoiding clumping. During operations, the material can be easily and securely positioned in the right place in the body. The fabric eventually breaks downinside the body of its own accord, rendering a further treatment to remove the dressing unnecessary. In addition to its use in wound healing, scaffolene technology opens up new therapeutic possibilities within other medical fields, including bio-surgery and regenerative medicine.

Good sound absorption in vehicles increases driver and passenger comfort. It also has a high priority in electric cars because electric drive trains cause less noise than combustion engines For this reason, other noise sources in different frequency ranges become more important. Freudenberg will be presenting innovative acoustic pads that provide outstanding sound absorption inside the vehicle. The light-weight pads help customers to save weight substantially and they are highly cost efficient. The pads are suitable for a wide variety of applications in the car such as door panels, headliners, trunk areas, wheel-houses and so on.
