- Loudspeaker covers requiring the finest pore structure and highest density in the PVC coated series, with UV and weather resistance for harshly exposed installations
- Air conditioner filter media requiring maximum fine-particle filtration in exposed or harsh-environment installations where PVC coating durability is specified
- Weep baffling in commercial and residential construction where the finest available PVC coated pore count and harsh-weather durability are both specified
- NEMA enclosure and generator or compressor housing ventilation where fine 60 PPI filtration, UV resistance, and long-term PVC weather durability are specified
- General filtering in exterior building assemblies demanding the finest pore structure and greatest mechanical strength in the fully specified PVC coated series
Common industries: construction, HVAC, fenestration, electrical enclosures, industrial equipment, audio.
The 60 PPI PVC Coated Reticulated Foam is a fine-pore, high-density grade in H-O Products’ PVC coated reticulated foam series, with a nominal cell count of 60 ppi and the lowest volumetric air flow rate among the fully specified PVC coated grades at 7.5 cfm ±1.5. This grade is tested to ASTM D3574-05 — a more current standard revision than the ASTM D3574-91 used for the 10, 20, 30, and 45 PPI grades.
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.
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 60 PPI grade has a higher density than the rest of the PVC coated series at 1.9 lb/ft³ ±0.10, the highest tensile strength at 30 lb/in minimum, and the highest elongation at 200% minimum. Compression set at 50% deflection is 15% loss maximum with an autoclave compression set loss of 10% maximum. Tear strength is 4.0 lb/in minimum. Tensile strength dry heat loss is 15% maximum. The 25% compression load deflection autoclave loss is 15% maximum. Flame retardant is available by special request.
What differentiates the 60 PPI PVC Coated grade from the 45 PPI and 80 PPI PVC coated grades?
The 60 PPI PVC Coated grade is tested to ASTM D3574-05 (not ASTM D3574-91 as used for the 10–45 PPI grades), has the highest density at 1.9 lb/ft³ ±0.10, the lowest volumetric air flow at 7.5 cfm ±1.5, the highest tensile strength at 30 lb/in minimum, and the full thickness range to 2". The 80 PPI grade has a reduced property set and does not list UV resistance. This 60 PPI grade is the finest-pore grade with a full ASTM D3574-05 specification and UV resistance listed on its TDS.
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 60 PPI PVC coated grade has a CFD of 0.65 psi ±0.20 at 25% per ASTM D3574-05, with a wider tolerance than the ASTM D3574-91 grades. This should be considered during installation in tight-tolerance loudspeaker covers and filter frames, and supports the most secure seating and consistent filtration contact at this fine pore count.
What is the service temperature range for the 60 PPI PVC 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 15% maximum and autoclave aging performance, all per ASTM D3574-05.
Is the 60 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 provides UV resistance rated Excellent at 252 hours per ASTM G154 and is described as best for harsh climate conditions.
How should the 60 PPI PVC Coated Reticulated Foam be specified?
Specify grade (60 PPI PVC Coated Reticulated Foam, Foam Grade T-60), 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.
