High-tech filtration materials

Decades of experience, pioneering technologies, a continuous development process, and professional support: Filtura® offers filter manufacturers all of this under one roof. These advantages are particularly important when developing customized solutions.

We work closely with our customers to develop the composite they need - from sophisticated HVAC solutions to activated carbon filter media with additional functionalities, including antiviral properties. By using different layer combinations and/or incorporating functional layers, we achieve the desired filtration performance, breathability, and mechanical strength.

Filtura® spunbond nonwovens provide a high degree of uniformity in terms of thickness, porosity, and surface properties. Thanks to their design, the fabrics are not only easy to laminate with membranes and other filtration layers, they also show no fraying during processing and throughout the lifetime of the finished filter element.

Filtura® spunbond nonwovens feature high longitudinal and transverse strength and rigidity. They therefore reliably remove impurities and help to create high, sharp, and stable pleats for maximum performance. The portfolio includes spunbond nonwovens with high permeability which helps to achieve low pressure drop, supporting cost-effective operation of the filter.

The Filtura® portfolio comprises spunbond nonwovens made from FDA-approved raw materials. With NSF certification, these fabrics are suitable for manufacturing water filter equipment.

Filtura® spunbond nonwovens can be customized to meet individual requirements. Typical modifiable factors include the polymers used (PP, PES, PE or PA), fabric weight per unit area, antibacterial properties, thickness, and permeability. Microfilament fabrics are also available.

Thanks to their excellent thermal resistance, tear strength and resistance to chlorine, bromine and other substances, Filtura® spunbond nonwovens maintain their properties even under the harshest conditions. Pleats created with these fabrics withstand high pressure and frequent cleaning.

Filtura® carded nonwovens can be customized to meet specific performance requirements by using various fiber combinations and distributions as well as finishing treatments. This flexibility allows characteristics such as strength, adsorbent behavior, and elasticity to be tailored as needed.

Filtura® carded media maximize dirt-holding capacity and flow rates. These features contribute to higher air quality and reduce the need for frequent filter changes.

The filtration efficiency of Filtura® meltblown nonwovens can be tailored to individual customer specifications. The fabrics are characterized by a wide air permeability range which allows a variety of different applications. In terms of materials, the nonwoven filter media can be made of different polymers (PET, PP, PE, PA, PBT and PBS) and can be combined with layers of our drylaid and spunbond nonwovens.

Additives can be integrated into the masterbatch polymers, including hydrophilic, colored, flame retardant, UV stabilization, and electrostatic charging agents. This avoids extra costs during the downstream manufacturing process.

With years of production experience, our processes have been optimized to achieve reliable and stable results. The precise pore size and uniform fiber distribution ensure excellent reliability in filtration applications, as well as homogeneity and outstanding performance.

The Filtura® range of wetlaid nonwovens includes product variants with very fine fibers (under 2µm), making them ideal for manufacturing sophisticated filter materials. The resulting increased surface area and denser fiber network maximize the filtration capacity of the filter media.

Filtura® wetlaid nonwovens can be made from a variety of polymers, such as PES, PO, PA and PVA, as well as different types of fiber. Among other options, the addition of glass, viscose, and wood pulp is possible.

Our portfolio includes product options ranging from extremely lightweight, at less than 10 grams per square meter, to options weighing up to 300 grams per square meter. This diverse range allows us to cater to a wide array of applications, ensuring that we meet the specific needs of our clients across different industries.

Filtura® 3D mats offer a broad range of “surface areas” as well as options for glueless bonding. The 3D mats can be manufactured in different weights, thicknesses (up to 22 mm) and colors, or shaped to different profiles. They can be compounded to achieve properties such as flame retardancy or UV stability.

The structure features a high surface area to volume ratio; the open flow channels support low pressure drop even at high air velocities. Filtura® 3D mats also have superior compression stability and uniformity.

Good news for filter manufacturers: Filtura® 3D mats are supplied on one meter wide rolls, are extremely lightweight and can be easily processed.
