80 PPI PVC Coated Reticulated Foam
65–80 PPI PVC Coated Open Cell Reticulated Polyether Polyurethane Foam
H-O Products 80 PPI PVC Coated Reticulated Foam is a compressible open cell polyether polyurethane foam with a nominal cell count of 65–80 ppi (CREST), a density of 0.3–0.5 lb/ft³, and a compression force deflection of 0.4–0.6 psi at 25% per ASTM D3574. The PVC coating is widely specified by architects for its durability and longevity and this grade is best suited for exposure to harsh climate conditions including driving rain, dust storms, and hail storms. It is the finest-pore and lowest-density grade in the PVC coated reticulated foam series.

Applications
- Loudspeaker covers requiring the finest available pore structure in the PVC coated series with PVC weather durability for harshly exposed installations
- Air conditioner filter media requiring maximum fine-particle filtration with PVC coating durability in harsh-climate installations
- Weep baffling in commercial and residential construction where the finest PVC coated pore count and harsh-weather durability are both specified
- NEMA enclosure and generator or compressor housing ventilation requiring the finest 65–80 ppi filtration with PVC coating durability within the 1/4″ to 1″ thickness range
- General filtering in exterior building assemblies requiring the finest pore structure in the PVC coated series with maximum weather protection
Common industries: construction, HVAC, fenestration, electrical enclosures, industrial equipment, audio.
The 80 PPI PVC Coated Reticulated Foam is the finest-pore and lowest-density grade in H-O Products’ PVC coated reticulated foam series, with a nominal cell count of 65–80 ppi and a density of 0.3–0.5 lb/ft³ — significantly lower than all other grades in the series.
The PVC coating provides UV resistance and durability widely specified by architects, and this grade is best for exposure to harsh climate conditions such as driving rain, dust storms, and hail storms. It is designed for loudspeaker covers, air conditioner filters, and general filtering and weep baffling in commercial and residential construction.
The TDS product description states “nominal 45 PPI”; however, the TDS title and cell count (65–80 ppi) confirm this is the 80 PPI grade.
Per the TDS note, the Crest visual PPI standard is the industry accepted nomenclature for defining reticulated foam pore size; however, the air flow is the only quantifiable value for determining PPI for published specifications, and the only exception allowed is if visual PPI is agreed as a standard in advance prior to order submission.
The TDS provides a reduced property set: density 0.3–0.5 lb/ft³, CFD 0.4–0.6 psi at 25%, tensile strength minimum 12 psi, and elongation 150% minimum, all per ASTM D3574 (no suffix). No volumetric air flow rate, compression set, tear strength, air pressure drop, UV resistance, or aging data is listed on the TDS for this grade. No foam grade designation is listed. Flame retardant is available by special request.
What differentiates the 80 PPI PVC Coated grade from the 60 PPI PVC Coated grade and from the 80 PPI Uncoated and Acrylic Coated grades?
The 80 PPI PVC Coated grade has the finest pore structure in the PVC coated series at 65–80 ppi and the lowest density at 0.3–0.5 lb/ft³ — substantially lower than the 60 PPI grade's 1.9 lb/ft³. Unlike the 60 PPI PVC coated grade, this grade does not list UV resistance on its TDS and provides a reduced property set tested to ASTM D3574 without the suffix. The PVC coating is best for harsh climate conditions, unlike the acrylic coated 80 PPI grade which is recommended for less severe weather exposure.
Why is compression force deflection important for a PVC coated reticulated foam?
Compression force deflection determines how readily the foam compresses to fill a cavity under installation force. The 80 PPI PVC coated grade has a CFD range of 0.4–0.6 psi at 25% per ASTM D3574. Despite its very fine pore structure and very low density, this CFD range is similar to the 60 PPI grade, and specifiers should consider the material's lower density and tensile strength (12 psi minimum) when evaluating installation force and structural requirements.
What is the service temperature range for the 80 PPI PVC Coated Reticulated Foam?
A specific service temperature range is not stated on the manufacturer's TDS for this material. No aging performance data is listed on the TDS for this grade.
Is the 80 PPI PVC Coated Reticulated Foam suitable for regulated environments?
No compliance standards are specified on the manufacturer's TDS for this material. A flame retardant formulation is available by special request. The PVC coating is described as best for harsh climate conditions, but UV resistance data is not listed on this TDS.
How should the 80 PPI PVC Coated Reticulated Foam be specified?
Specify grade (80 PPI PVC Coated Reticulated Foam, cell count 65–80 ppi), thickness, color (Black), compliance requirements if applicable, dimensional tolerances, and finished format. Per the TDS, air flow is the only quantifiable value for determining PPI for published specifications.
