Filtration
Polytech® Reticulated Foam, Type - S
Polytech® Reticulated Foam, Type - S (PRF), is an ester based urethane foam in which the membrane windows of the foam’s cell structure have been thermally removed.
| Density: 1.8 lb/ft³ | |
| Temperature Range: -40 deg F to 225 deg F. | |
| Flamability: 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 include heavy-duty air filters for trucks, buses and off-highway equipment.
Polytech® Reticulated Foam, Type - T
Polytech® Reticulated Foam, Type - T (PRF-T) is an ether based urethane foam in which the membrane windows of the foam’s cell structure have been thermally removed.
| Density: 1.8 lb/ft³ | |
| Temperature Range: -40 deg F to 225 deg F. | |
| Flamability: 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 include heavy-duty air filters for trucks, buses and off-highway equipment.
Polytech® Reticulated Felted Foam
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 deg F to 225 deg 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 include medical and business equipment.
Polytech® Drip-Dry Reticulated Foam
Polytech® Drip-Dry Reticulated Foam (PRF-DD25) is a reticulated ether based polyurethane foam that sheds water and dries rapidly after exposure to rain, snow, washing or other forms of moisture.
| Density: 2 lb/ft³ | |
| Temperature range: -40 deg F to 225 deg F | |
| Flammability: UL900 Class 2 Filter Media. | |
| Exceptional sound attenuation, effective over a wide range of frequencies. |
Applications include radiator filters on outdoor equipment and also as air and/or water filters.
