HyPUR-cel® I0712
HyPUR-cel® I0712 is an open cell polyurethane foam with a typical density of 7 pcf and a 25% Compression Deflection of 12 psi per ASTM D1056. The material operates across a service temperature range of -40°F to 250°F. I0712 delivers a firmer compression profile than the I0705 within the same density class, offering higher load-bearing capacity with the breathability and dimensional stability of the HyPUR-cel® series.

HyPUR-cel® I0712 is an open cell polyurethane foam in the HyPUR-cel® I-series occupying the firmer compression position within the 7 pcf density class. Its 25% Compression Deflection of 12 psi makes it appropriate for industrial gasketing, load-bearing cushioning, and sealing assemblies where resistance to higher compressive forces is required.
The foam delivers strong tensile performance at 85 psi and maintains a compression set of 2.8% per ASTM D1056, supporting reliable shape retention in demanding seal designs. Its open cell structure allows air and moisture passage, and the material is available with adhesive laminations, fabrics, films, and custom coatings. Custom color matching is available using fully reacted colorants. No flammability compliance standard is listed on the manufacturer’s TDS for this grade.
What differentiates I0712 from I0705 within the 7 pcf density class?
I0712 delivers a 25% Compression Deflection of 12 psi versus 5 psi for the I0705, providing significantly greater resistance to compression under load. It is the appropriate choice when higher sealing force or structural support is required at the 7 pcf density level.
Why is compression set critical for foam sealing and gasketing applications?
Compression set measures the permanent deformation a foam retains after being held under deflection. I0712 achieves 2.8% compression set per ASTM D1056, indicating strong recovery that helps the foam maintain its thickness and sealing contact even after prolonged compressive loading.
What is the service temperature range for I0712?
I0712 is rated for continuous service from -40°F to 250°F as listed on the TDS.
Is I0712 suitable for automotive flammability-regulated environments?
No flammability compliance standard is listed on the manufacturer's TDS for I0712. Suitability for flammability-regulated environments should be confirmed through independent testing.
How should I0712 be specified?
Specify grade (I0712), thickness, color if applicable, dimensional tolerances, and finished format.
