80 PPI Acrylic Coated Reticulated Foam
H-O Products 80 PPI Acrylic 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 acrylic coating provides UV resistance rated Excellent at 252 hours per ASTM G154, and is an economical alternative to PVC coating for applications not exposed to harsh climate conditions. It is the finest-pore and lowest-density grade in the acrylic coated reticulated foam series.

Common industries: construction, HVAC, fenestration, electrical enclosures, industrial equipment.
The 80 PPI Acrylic Coated Reticulated Foam is the finest-pore and lowest-density grade in H-O Products’ acrylic 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 acrylic coating provides UV resistance, making the material available in black and suitable for UV-exposed applications.
It is an economical alternative to PVC coating for applications not exposed directly to harsh climate conditions such as driving rain, dust storms, or hail storms. It is designed for air conditioner filters, general filtering applications, 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 -91 suffix). No volumetric air flow rate, compression set, tear strength, air pressure drop, 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 Acrylic Coated grade from the 60 PPI acrylic grade and from the 80 PPI Uncoated grade?
The acrylic coating adds UV resistance rated Excellent at 252 hours per ASTM G154, making this grade suitable for UV-exposed applications where the uncoated 80 PPI grade cannot be used. The 80 PPI acrylic coated grade is the finest-pore grade in the acrylic coated series at 65–80 ppi and has the lowest density — 0.3–0.5 lb/ft³ — which is substantially lower than the 60 PPI acrylic grade's 1.4–1.6 lb/ft³ range. Its tensile strength minimum of 12 psi is the lowest in the acrylic coated series, reflecting the very fine, open skeletal structure at this pore count.
Why is compression force deflection important for an acrylic coated reticulated foam?
Compression force deflection determines how readily the foam compresses to fill a cavity under installation force. The 80 PPI acrylic coated grade has a CFD range of 0.4–0.6 psi at 25% per ASTM D3574. Despite its very fine pore structure and significantly lower bulk density compared to the 60 PPI grade, this CFD range is similar, reflecting the interaction between pore density and the very low bulk density of this grade.
What is the service temperature range for the 80 PPI Acrylic 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 Acrylic 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 TDS notes that the acrylic coating is suitable as an economical alternative to PVC when the foam is not exposed directly to harsh climate conditions such as driving rain, dust storms, or hail storms.
How should the 80 PPI Acrylic Coated Reticulated Foam be specified?
Specify grade (80 PPI Acrylic 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.
