Freudenberg Performance Materials, a German manufacturer, rolled out a new lineup of fine denier spunbond nonwoven materials. The company’s latest offerings are made from a mix of polymers-like PET, PE, and PP-and can be tailored with different fiber types and blends, including combinations such as PET/PE, PET/coPET, and PET/mPP. These materials use both mono and bico fibers, with titer ranging from 2.5 to 3 dtex and weights from 17 to 140 gsm. They’re bonded using thermal methods, either flat calendering or point sealing, resulting in lightweight yet strong nonwovens with smooth surfaces.
For the construction sector, the materials are especially well-suited for roofing and facade membranes, vapor barriers, and house wrappings. They complement Freudenberg’s existing Terbond®, Texbond®, and Colback® lines, bringing mechanical strength, high nail tear resistance, and strong UV and temperature stability-especially in PET-based options.
In filtration, the company markets these solutions under the Filtura® brand. They’re designed for liquid filtration, such as in coolants and lubricants, and offer high efficiency and a regular surface. New options include PET-PA and PET-PE blends, and the materials also act as protective layers for glass fiber, nano, and activated carbon support media.
For packaging, fully synthetic PET/PE fine denier nonwovens are ideal for desiccant bags and dehumidifier products. Their hot sealing capabilities allow for fast, efficient production without extra chemical treatments, while also delivering high strength and durability.
In the coating industry, these materials serve as substrates for various coating, laminating, and concealing applications. They’re chemically resistant, thermally stable, and can be customized-such as a very lightweight, flat-bonded variant perfect for cold wax depilatory strips, which requires both strength and flexibility.
Beyond these core uses, the materials also find applications in agriculture as crop covers, as well as in decoration and other industrial or consumer products.
