HyPUR-cel® I1507L
HyPUR-cel® I1507L is a low-resiliency, energy-absorbing open cell polyurethane foam with a typical density of 15 pcf (12–18 pcf tolerance) and a 25% Compression Deflection of 7 psi (5–10 psi tolerance) per ASTM D1056. The “L” designation identifies a formulation with 13% resilience per ASTM D2632 that dissipates impact and vibration energy with fast recovery and low hysteresis loss. The material operates across a service temperature range of -40°F to 250°F, achieves a flammability pass rating per FMVSS-302 at 0.063″ or thicker, and combines 90 psi tensile strength and 130% elongation with exceptionally low compression set (0.3% per ASTM D1056).

HyPUR-cel® I1507L is the softest of the low-resiliency “L” grades in the HyPUR-cel® I-series, pairing a 15 pcf density with a 25% Compression Deflection of 7 psi. Where a standard I-series grade returns energy on rebound, the L formulation absorbs it: resilience is 13% per ASTM D2632, so the foam damps impacts and vibration and recovers quickly with low hysteresis loss.
Compression set is exceptionally low at 0.3% per ASTM D1056 and 0.85% per ASTM D3574, and the foam retains the excellent high-temperature compression set, superb compression fatigue properties and dimensional stability of the series. Tensile strength of 90 psi, 130% elongation and 12 lb./in tear strength support clean die-cutting, and the material accepts adhesive laminations, fabrics, films and custom coatings.
Compliant with FMVSS-302 (Pass @ 0.063″ or thicker).
What differentiates I1507L from I1710L and I2015L within the HyPUR-cel® I-series?
All three are low-resiliency "L" grades with about 13% resilience. I1507L is the softest and lightest at 15 pcf and 7 psi Compression Deflection, I1710L steps up to 17 pcf and 10 psi, and I2015L to 20 pcf and 15 psi. I1507L is specified when energy absorption is needed at the lowest closure force.
What does the "L" in I1507L mean?
Per Rubberlite's naming convention, the first two digits are density (15 pcf) and the last two are 25% compression deflection (7 psi). The "L" identifies a low-resiliency, energy-absorbing product: I1507L has 13% resilience per ASTM D2632, so it dissipates impact and vibration energy with fast recovery and low hysteresis loss rather than rebounding like a standard I-series grade.
What is the service temperature range for I1507L?
I1507L is rated for continuous service from -40°F to 250°F as listed on the Rubberlite property sheet.
Is I1507L suitable for automotive flammability-regulated environments?
Yes. I1507L 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 I1507L be specified?
Specify grade (I1507L), thickness, compliance requirements (FMVSS-302 if required), dimensional tolerances, and finished format (roll, sheet or die-cut part), plus any adhesive, film or fabric lamination.
