- Air conditioner filter media requiring fine-pore filtration with UV resistance for outdoor or exposed installations
- Weep baffling in commercial and residential construction where fine particulate filtration is required alongside UV resistance, in applications not subject to harsh weather conditions
- General filtering applications requiring fine particulate exclusion with UV-stable foam across the full available thickness range to 2″
- NEMA enclosure and generator or compressor housing ventilation where finer filtration and UV resistance are both specified
- Moisture and air infiltration barriers in building envelope assemblies requiring fine 30 PPI pore structure with UV stability for sunlight-exposed installations
Common industries: construction, HVAC, fenestration, electrical enclosures, industrial equipment.
The 30 PPI Acrylic Coated Reticulated Foam is a fine-pore grade in H-O Products’ acrylic coated reticulated foam series, with a nominal cell count of 30 ppi and a volumetric air flow rate of 18 cfm ±2. The acrylic coating provides UV resistance in black and 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.
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.
Compression force deflection at 25% is 0.55 psi ±0.10. Compression set at 50% deflection is 25% loss maximum. Tensile strength is 20 lb/in minimum with a dry heat loss maximum of 20%. Elongation at break is 180% minimum. Tear strength is 5 lb/in minimum. Air pressure drop is 0.15 ±0.05 per ASTM D3574-91. Autoclave compression set loss is 25% maximum and 25% compression load deflection autoclave loss is 15% maximum. Flame retardant is available by special request.
No compliance standards are specified on the manufacturer’s TDS for this material.
What differentiates the 30 PPI Acrylic Coated grade from the 30 PPI Uncoated grade and from the 20 PPI and 45 PPI acrylic coated grades?
The acrylic coating adds UV resistance rated Excellent at 252 hours per ASTM G154, making this grade suitable for UV-exposed installations where the uncoated 30 PPI grade cannot be used. Within the acrylic coated series, the 30 PPI grade provides finer filtration than the 20 PPI at a lower air flow of 18 cfm ±2 and has a higher allowable compression set at 50% deflection (25% loss maximum) and autoclave compression set loss (25% maximum) than the coarser grades. The full thickness range to 2" is available on the 30 PPI acrylic grade but not on the 45, 60, or 80 PPI acrylic grades.
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 30 PPI acrylic coated grade has a CFD of 0.55 psi ±0.10 at 25% — higher than the coarser grades — reflecting its finer, denser skeletal structure. This moderate resistance supports consistent seating in filter frames and building envelope assemblies where the foam must maintain reliable contact with the cavity walls for effective filtration.
What is the service temperature range for the 30 PPI Acrylic Coated Reticulated Foam?
A specific service temperature range is not stated on the manufacturer's TDS for this material. Aging performance data includes tensile strength dry heat loss of 20% maximum per ASTM D3574-91 and autoclave aging performance per ASTM 3574-91 and ASTM D3574-91.
Is the 30 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 30 PPI Acrylic Coated Reticulated Foam be specified?
Specify grade (30 PPI Acrylic Coated Reticulated Foam, Foam Grade T-30), 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.
