- Loudspeaker covers requiring the coarsest pore structure and maximum air flow in the PVC coated series with UV and weather resistance for harshly exposed installations
- Air conditioner filter media in exposed or outdoor installations where PVC coating durability and longevity are specified by architects
- Weep baffling in commercial and residential construction where harsh climate conditions including driving rain, dust storms, and hail storms require PVC coating durability
- NEMA enclosure and generator or compressor housing ventilation where maximum air flow and long-term UV and weather resistance are specified
- General filtering applications in exterior building assemblies requiring the highest air flow in the PVC coated series with durable weather protection
Common industries: construction, HVAC, fenestration, electrical enclosures, industrial equipment, audio.
The 10 PPI PVC Coated Reticulated Foam is the most open-pore grade in H-O Products’ PVC coated reticulated foam series, with a nominal cell count of 10 ppi and the highest volumetric air flow rate in the series at 25.5 cfm ±4.5. 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, general filtering applications, and weep baffling in commercial and residential construction, where it weeps moisture and condensation while minimizing infiltration of air, moisture, insects, and dust into buildings and cavities including NEMA enclosures and generator and compressor housings.
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 0.30 psi minimum. Compression set at 50% deflection is 15% loss maximum. Tensile strength is 5 lb/in minimum with a dry heat loss maximum of 15%. Elongation at break is 100% minimum. Tear strength is 2 lb/in minimum. Air pressure drop is 0.15 ±0.05 per ASTM D3574-91. Autoclave compression set loss is 15% maximum and 25% compression load deflection autoclave loss is 30% maximum. Flame retardant is available by special request.
What differentiates the 10 PPI PVC Coated grade from the 20 PPI, 30 PPI, 45 PPI, 60 PPI, and 80 PPI PVC coated grades?
The 10 PPI PVC Coated grade has the largest pore size and highest volumetric air flow at 25.5 cfm ±4.5 in the PVC coated series, as well as the widest available thickness range extending to 2". The PVC coating is widely specified by architects for durability and longevity and is best for harsh climate conditions including driving rain, dust storms, and hail storms. Its tensile strength (5 lb/in minimum) and tear strength (2 lb/in minimum) are the lowest in the fully specified PVC grades, reflecting its most open skeletal structure.
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 10 PPI PVC coated grade has a CFD of 0.30 psi minimum at 25% — the lowest in the fully specified PVC coated series — meaning it compresses easily under minimal force while its large open pore structure allows maximum air and moisture flow, important for loudspeaker covers and high-air-flow filtration applications.
What is the service temperature range for the 10 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 per ASTM D3574-91 and autoclave aging performance per ASTM 3574-91 and ASTM D3574-91.
Is the 10 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 and is described as best for harsh climate conditions.
How should the 10 PPI PVC Coated Reticulated Foam be specified?
Specify grade (10 PPI PVC Coated Reticulated Foam, Foam Grade T-10), 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.
