polyniq®: Specialty Polymer Meltblown Media for demanding Applications in Industrial Filtration

    The requirements for filter media vary widely in industrial filtration. While standard polymers suffice for many processes, high temperatures, aggressive chemicals, and specific sustainability requirements require carefully selected materials. It is often not the design of the filter that determines a system’s performance, but rather the choice of polymer.

    polyniq® by Sandler is a series of meltblown media based on a range of specialty polymers. Each material has specific properties which make it suitable for certain applications in industrial filtration.

      polyniq® - what's it all about?

      polyniq® is Sandler Group's line of specialized filter solutions for demanding meltblown applications in industrial filtration. Instead of standard polymers, polyniq® utilizes specialty polymers, such as PPS, PBT, PA6, PA12, PLA, PBAT, and TPU. Those polymers are processed into custom filter media. Polyniq® is not an off-the-shelf product, but rather a customized solution to a specific challenge, with application-specific dimensions and properties.

      Effectively, polyniq® is not as much a catalog of products as it is a material based modular system creating performance from thoughtfully combining polymer, fiber structure, and process parameters.

      Why should I use PPS Meltblown Filter Media?

      The choice of the right polymer always depends on its specific application: on operating temperatures, the media involved, the mechanical requirements. For applications under extreme conditions, PPS (polyphenylene sulfide) is often the first choice.

      The unique properties of PPS make it the preferred option for industrial filtration under extreme conditions:

      • Thermal Stability up to and over 200°C/ 392°F. Ideal for filters in exhaust and hot gas applications.
      • Chemical Resistance to solvents, oils and aggressive process media
      • Dimensional Stability also under continuous mechanical and thermal stress

      The use of PPS polymer meltblown filters makes sense whenever classical polymers like PP or PET degrade quickly. With polyniq®, Sandler turns the resistiveness and thermal stability of PPS into process-capable, ready-to-market meltblown fabrics for industrial filtration.

        Are there Specific Materials for Liquid Filtration?

        Filtration does not mean air or gas phase filtration only. Also in the field of liquid filtration, polyniq® makes strategic use of specific polymers:

        PBT (Polybutylene Terephtalate):
        PBT features a high resistance against diesel and other fuels as well as a low moisture absorption - at considerably lower cost than other high-performance polymers.

        PA6 (Polyamide 6):
        PA6 is a specialty polymer combining natural hydrophilicity with excellent wear-resistance and mechanical robustness. These features make PA6 meltblown media ideal for aqueous applications.

        PA12 (Polyamid 12):
        This specialty polymer features a low moisture absorbency, a good wettability, and a high resistance fuels, lubricants and salt solutions, properties that render PA12 optimally qualified for the filtration of demanding liquid media.

        polyniq® is all about synthetic polymers. How about the ecological footprint?

        Do synthetic resins and an ecological mindset go together? With polyniq® they do. Sandler has an eye on the ecological footprint and offers two bio-based, respectively compostable options:

        PLA (Polylactic Acid):
        PLA excels as a sustainable material made from renewable feedstocks. This specialty polymer is industrially compostable and boasts good strength properties and low density—making it ideal for eco-friendly filtration solutions. With PLA, Sandler Group polyniq® makes for eco-friendly and functional filter media.

        PBAT (Polybutylene Adipate Terephthalate):
        PBAT combines elasticity with compostability, making it an ideal candidate for sustainable meltblown media. Wherever flexible structures, ease of processing and a reduced ecological footprint are in demand, this polymer really shines.

          Custom Filter Media directly from the Producer

          Sourcing filter media for special applications directly from the producer secures crucial advantages: specific weights and widths, as well as customized fiber structures.

          Sandler supports you all the way from material selection and lab validation to series production. With over 25 years of meltblown experience, Sandler Group is a trusted partner in the development of filter solutions focusing on optimization of the material rather than providing off-the-shelf products.
