Leading the way: high-tech nonwovens for fuel cells

Whether in the automotive industry as propulsion unit or range extender, whether for consumer electronics, forklift trucks, aerospace, back-up power or stationary electricity or power generation, fuel cell technology is becoming increasingly prevalent. Developed specifically for this pioneering market, gas diffusion layers (GDL) from Freudenberg Performance Materials are characterized by excellent quality standards and exceptional functional flexibility. Perfect management of reaction media optimized for all operation modes, high thermal and electric conductivity, optimum protection of the membrane against damage and very good processing properties are just a few of the features that characterize these advanced nonwovens.

Light Diffuser from Freudenberg: nonwovens for uniform light distribution in LED luminaires

Modern LED lighting systems require optical components. The aim is to transform punctiform light sources into a homogenously lit surface.

Innovative Light Diffuser from Freudenberg are precisely tailor-made for this requirement. The high performance nonwovens based on special polyester fibers disperse light points - even at short distances from the light source. In addition, the diffusers achieve an excellent light output ratio and lighter, more compact lighting solutions. The light scattering media can be perfectly integrated into existing light constructions without having to change the design. Different weight versions for setting-defined opacity, as well as film reinforced and self-adhesive versions, offer manufacturers and planners a high degree of flexibility - for sophisticated and cost efficient lighting systems.

Optimum safety in battery cells: nonwovens as battery separators

The product portfolio of Freudenberg Performance Materials includes high-performance separators for various applications and cell types. They all guarantee reliable separation, high energy efficiency, easy and economical installation, and safe operation.

Lithium-ion batteries, such as those used in the automotive industry, place especially high demands on separators, which play a decisive functional role. With our special separators for lithium-ion batteries, Freudenberg Performance Materials offers pioneering solutions in this area. These separators are made from ultra-thin PET nonwovens impregnated with ceramic particles. This enables a higher energy density to be achieved while simultaneously significantly increasing the safety of the battery cells.

Reliable protection: nonwovens for the cable industry

Freudenberg Performance Materials manufactures high-quality nonwovens for almost any application in the cable industry. Our products are part of modern cable constructions and effectively protect cables against water penetration during the entire service life. Our product portfolio includes conductive and non-conductive water blocking tapes as well as binding, bedding and separation tapes. Because we are constantly adding new solutions to our portfolio, customers can find not only nonwovens for use in medium voltage cables, special, telecommunication and fiber-optic cables, but also high-tech solutions for high-voltage and submarine cables.

Safety through expertise: nonwovens for the electrical industry

Nonwovens from Freudenberg Performance Materials make a crucial contribution to providing consumers, industry and public institutions with safe electricity. These nonwovens are continuously temperature resistant, durable and feature high impregnability, making them suitable for a wide variety of functions. In motors, generators and transformers, they act as a central component in phase and layer insulation and as a spacer between components. We also offer thermally extremely durable nonwovens for high-performance applications, which retain their efficiency even under tough conditions.

Super Caps

Known in the industry as ‘super caps’, supercapacitors are high-performance capacitors that work in a similar way to these batteries and have a particularly high capacity. Freudenberg Performance Materials has developed special ‘separator nonwovens’ especially for this application. Super caps can store and discharge energy very quickly, when necessary. They are used, for example, during the lifting and lowering of containers when loading and unloading ships.

Top performance und extreme versatility: technical textiles for redox flow batteries

Redox flow batteries are extremely efficient and have a longer lifetime than conventional batteries. These accumulators can store large amounts of energy for several hours and release it any time. Therefore they are perfect for managing peak loads in power plants or as energy storage for solar plants in remote areas. Freudenberg Performance Materials offers nonwoven electrodes which are designed to optimize the efficiency of redox flow batteries. The operating principle: Thanks to their unique three-dimensional fiber structure, they improve liquid circulation in these redox flow batteries. The electrodes can be customized to various customer demands, offering manufacturers a high degree of flexibility .
