Materials Selection

Materials selection is the single most important aspect in the development of any filter or molded component. Without proper materials, manufacturability can be compromised and product performance suffers. Working with your Filtertek technical specialist, you can be assured that the materials selected for your project are the best available for your unique requirements.

Some important considerations in product material selection include:

  • Chemical & fluid compatibility
  • Operating temperature
  • Operating pressure
  • Manufacturing processes
  • Sterilization technique (if applicable)
  • Product dimensions and tolerances
  • Product performance requirements


As the largest single user of filtration screen media in North America, we focus on keeping costs low and our prices competitive. Filtertek has developed significant expertise and proprietary processes to convert many different types of filter media into shapes that can be efficiently insert-molded. Our stringent quality systems ensure that all incoming materials meet the highest standards, reducing product variability.

Membrane (0.02µ – 10µ +)
  • Acrylic c
  • -polymer
  • Cellulose acetate
  • Fluoropolymers
  • Nylon
  • Polyester
Woven Synthetic Screen (1µ - 1000µ +)
  • Nylons (Polyamides)
  • Polyester (Polyethylene Terephalate)
  • Polypropylene
  • Polyethylene
  • Fluoropolymers
  • Other special materials on request
Woven Metallic Screen (2µ - 1000µ+)
  • Steel, including carbon and stainless
  • Other alloys available
Other Media
  • Extruded synthetic mesh
  • Polyurethane foam
  • Cellulose paper
  • Non-wovens
    • Meltblown
    • Spun bonded
    • Needled felts
