Freudenberg Performance Materials expands its material portfolio with fine denier spunbond nonwovens, designed for applications in construction, filtration, packaging, and coating. The materials are based on fine filament nonwoven technology, which, according to the company, is characterized by flexibility, adaptability, and a broad range of possible applications.
Material properties and production capabilities
The spunbond nonwovens are manufactured using mono- or bico-fibers with titers ranging from 2.5 to 3 dtex. Various polymers such as PET, PE, or PP are used, as well as combinations like PET/PE, PET/coPET, or PET/mPP. The material weight spans 17 to 140gsm.
According to the company, the materials are characterized by high tensile strength and tear resistance as well as a smooth and even surface. The flexible production technology is designed to enable a wide range of customization options.
Use in the construction industry
In the construction sector, the fine denier spunbond nonwovens are used in roofing and facade membranes, vapor barriers, and house wrappings. In addition to existing solutions such as Terbond, Texbond, and Colback, the new materials are said to offer mechanical strength, high nail tear strength and high UV and temperature resistance. According to the company, the PET composition used contributes to long-term stability.
Applications in liquid filtration
In liquid filtration, the spunbond nonwovens are part of the Freudenberg brand Filtura. They are used for the filtration of coolants and lubricants, among other things. The materials are designed to offer high efficiency and a regular surface. Moreover, they can also be combined with support media applications for glass fiber, nano, and activated carbon.
Packaging solutions and coating applications
In the packaging sector, the fine denier spunbond nonwovens can be used as a cover material for desiccant bags and other dehumidifier products, for example. The materials are designed to enable efficient processing without chemical binders and, according to the company, offer high strength, high abrasion resistance, and high durability.
Furthermore, the spunbonded nonwovens are used as substrates for coating, laminating, and covering applications. According to Freudenberg, their chemical resistance, thermal stability, and smooth and even surface structure contribute to high-quality coating results.
Additional applications
Other applications for Freudenberg’s fine-denier spunbond technology include protective nonwovens in agriculture, decoration applications, and other industrial or consumer uses.
