60 PPI PVC Coated Reticulated Foam UL94 HF-1
60 PPI PVC Coated Reticulated Foam UL94 HF-1 is a PVC-coated open cell polyether polyurethane foam with a cell count range of 55–65 ppi, a density of 1.4–1.6 lb/ft³ ±0.10, and a tensile strength minimum of 20 psi. The material is designed to weep moisture while minimizing the infiltration of drafts, water, dust, and insects into buildings, NEMA enclosures, and generator or compressor housings. The PVC coating provides UV resistance rated as Excellent after 252 hours per ASTM G154, and the foam carries a UL94 HF-1 flame rating.

The 60 PPI PVC Coated Reticulated Foam UL94 HF-1 is a very fine-grade, PVC-coated reticulated polyether polyurethane foam with a cell count range of 55–65 ppi. This grade is suited for applications requiring fine filtration and environmental barrier performance, including loudspeaker covers, air conditioner filters, and weep baffling in commercial and residential construction where fine particulate exclusion is required.
The PVC copolymer coating delivers UV resistance and durability specified for exterior and semi-exposed applications. The foam is rated for harsh climatic exposure including driving rain, dust storms, and hail, providing a moisture-weeping barrier against air, insect, and particulate infiltration. The density range of 1.4–1.6 lb/ft³ reflects the tighter cell structure of this grade relative to coarser grades in the series.
Compliant with UL94 HF-1.
What differentiates 60 PPI PVC Coated Reticulated Foam UL94 HF-1 from the 45 PPI and 80 PPI grades?
The 60 PPI PVC Coated Reticulated Foam UL94 HF-1 spans a cell count range of 55–65 ppi, providing finer filtration than the 45 PPI grade while having a higher density range (1.4–1.6 lb/ft³) and higher tensile strength minimum (20 psi) than the 80 PPI grade (12 psi minimum, 0.3–0.5 lb/ft³). It is the appropriate selection when fine filtration is required alongside greater structural integrity than the finest grade in the series.
Why is compression set critical for a reticulated foam used in filtration and environmental sealing applications?
Compression set measures the permanent deformation a foam retains after sustained compression. In barrier and filtering applications, the foam is typically installed under compression. Excessive compression set means the foam will not recover its original thickness over time, reducing sealing effectiveness and increasing infiltration of contaminants, moisture, and insects. No compression set value is specified on the TDS for this grade; the TDS should be consulted for updated data if this property is critical to the application.
What is the recommended service temperature range for 60 PPI PVC Coated Reticulated Foam UL94 HF-1?
No service temperature range is specified on the manufacturer's TDS for this material.
Is 60 PPI PVC Coated Reticulated Foam UL94 HF-1 suitable for flame-rated environments?
Yes. This grade carries a UL94 HF-1 rating as stated on the TDS.
How should 60 PPI PVC Coated Reticulated Foam UL94 HF-1 be specified?
Specify grade (60 PPI PVC Coated Reticulated Foam UL94 HF-1), thickness, color (Black), compliance requirements (UL94 HF-1), dimensional tolerances, and finished format.
