HyPUR-cel® I0906 is an open cell polyurethane foam in the HyPUR-cel® I-series formulated for sealing, cushioning, and gasketing applications requiring breathability and sustained performance. At 7 pcf with a 25% Compression Deflection of 5 psi, it occupies the soft end of the 7 pcf density class and is designed for applications where long-term seal retention under low to moderate compressive loads is essential.
The foam demonstrates excellent high-temperature compression set resistance and superb compression fatigue properties, maintaining sealing effectiveness through extended operating cycles. Tensile strength of 65 psi and elongation of 115% support good handling and fabrication characteristics. The material accepts adhesive laminations, fabrics, films, and custom coatings for converted component applications.
Compliant with FMVSS-302.
What differentiates I0906 from I0705 given both share a 5 psi compression deflection at 7 pcf?
While I0906 and I0705 share a similar compression deflection value, I0906 carries a tighter density tolerance (7–11 pcf) and a tighter compression set limit under ASTM D3574 (10% max vs. 15% max), indicating a formulation tuned for more demanding sealing performance in applications requiring closer dimensional consistency.
Why is compression set critical when selecting a foam for sealing applications?
Compression set measures the permanent deformation retained after sustained deflection. I0906 achieves 1.4% per ASTM D1056 and 7% per D3574, both within tight tolerance limits, ensuring the foam recovers effectively after loading and maintains continuous sealing contact over the product's service life.
What is the service temperature range for I0906?
I0906 is rated for continuous service from -40°F to 250°F as listed on the TDS.
Is I0906 suitable for automotive flammability-regulated environments?
Yes. I0906 achieves a pass rating per FMVSS-302 at 0.063" or thicker, making it suitable for automotive interior applications subject to Federal Motor Vehicle Safety Standards flammability requirements.
How should I0906 be specified?
Specify grade (I0906), thickness, compliance requirements (FMVSS-302 if required), dimensional tolerances, and finished format.
