Filtration Control Materials

Polymer Product Solutions

As a foam fabrication company, Polymer Technologies has been developing an assortment of products and materials for countless applications. We manufacture a variety of reticulated urethane foams with filtration control properties, available in a range of pore sizes from 10 to 90 ppi depending on style of foam selected and application purposes.  Our filtration materials are perfect complements to the other composite materials we produce. With applications in industries like HVAC, heavy trucks, and medical equipment as well as fabrication in almost any shape, size, or purpose, there are infinite possibilities with our filtration foams.

Our engineers will dissect your problems and develop an unparalleled solution.

Below is a sampling of our filtration products:

POLYTECH® Reticulated Foam, Type - S (PRF-S)

POLYTECH® Reticulated Foam, Type - S (PRF-S), is an ester based urethane foam in which the membrane windows of the foam’s cell structure have been thermally removed.

Polytech<sup>®</sup> Reticulated Foam, Type - S
  • Density: 1.8 lb/ft³
  • Temperature Range: -40°F to +225°F
  • Flammability: UL900 Class 2 Filter Media
  • Available in a range of pore sizes from 10 to 90 ppi.
  • Completely open celled, consistent cell structure.
  • Easily fabricated for a wide variety of uses.

Applications typically include heavy-duty air filters for trucks, buses and off-highway equipment.

POLYTECH® Reticulated Foam, Type - T (PRF-T)

POLYTECH® Reticulated Foam, Type - T (PRF-T) is an ether based urethane foam. As with Type – S, the membrane windows of the foam’s cell structure have been thermally removed.

Polytech<sup>®</sup> Reticulated Foam, Type - T
  • Density: 1.8 lb/ft³
  • Temperature Range: -40°F to +225°F
  • Flammability: UL900 Class 2 Filter Media
  • Available in a range of pore sizes from 10 to 60 ppi.
  • Increased stiffness over the Type S reticulated foams; Hydrolytically stable

Applications typically include heavy-duty air filters for trucks, buses and off-highway equipment

POLYTECH® Reticulated Felted Foam (PRFF-900ZB)

POLYTECH® Reticulated Felted Foam (PRFF-900ZB) is a flexible compressed urethane foam. PRFF is made from a reticulated ester or ether based polyurethane open-cell foam.

  • Density: 5.7 lb/ft³ (after compression)
  • Temperature Range: -40°F to +225°F
  • Flammability: UL900 Class 2 Filter Media.
  • Exceptional sound attenuation, effective over a wide range of frequencies.
  • Exhibits outstanding filtration efficiency, high physical strength, excellent abrasion resistance, and oil wicking characteristics.

Applications typically include medical and business equipment.
