ADDITIONAL PROPERTIES FOR TECHNICAL PAPERS
GESSNER impregnates its special technical papers using a process based on methanol or water. Impregnating with phenolic, epoxy, acrylic resins or latex gives high strength, dimensional stability and improves resistance to solvents, chemicals and high temperatures.
Special additives, depending on need, can be added to give further functionality. For example, hydrophobic, hydrophilic or oleophobic properties, flame retardancy, various colors, UV stability, bactericides, fungicides, etc, can all be built-in. Using further coating devices, we can add still further functionalities.
ASYMMETRIC SATURATION
GESSNER's ability of an asymmetric saturation process provides many different functionalities of cellulose-based media. Utilising an asymmetric saturation process is essential for ensuring that impregnation filter media can provide optimal filtration capabilities when used in a range of industrial settings, especially when it comes to customized and very special requirements. GESSNER mentions below only a few examples of what is possible by using this special process.
- benefits of curing and non-curing resins in one single medium for filter manufacturers. Our two-sided media provides different characteristics which unlocks advantages for our products & converters in a brand-new way

- superior converting for filter manufacturer of paper-processing industries to combine paper by an ultrasonic welding process on the paper-side without any additional glues or adhesives
LEARN MORE
- physical advantages for filter elements but also processing advantages for converters, e.g. One medium – two surfaces with different properties: Improved dust holding capacity and flame retardancy while offering you tailor-made converting advantages

ECO-FRIENDLY LIGNIN SATURATION
Our lignin-saturated cellulose filter media represents a breakthrough in sustainable filtration technology, offering unmatched performance without compromising environmental responsibility. Designed with a strong commitment to reducing carbon footprints and saving of fossil resources, our lignin saturated media is meticulously engineered to provide high-efficiency filtration that meets the highest standards.
The outstanding properties of cellulose in saturation processes make our eco-friendly cellulose media a perfect solution in a wide range of filtration applications, from transportation to various industrial purposes.
By adding the eco-friendly lignin saturation we developed a more sustainable product that does not compromise on filtration performance nor on its mechanical properties. Additionally, it decreases the formaldehyde emissions during the curing process.
Compared to standard media with a fossil-based resin saturation initial calculations show that the new lignin-based saturation filter media offers an improved product carbon footprint.
