HyPUR-cel® R1510
HyPUR-cel® R1510 is an open cell polyurethane foam with a typical density of 15 pcf (12–18 pcf tolerance) and a 25% Compression Deflection of 10 psi per ASTM D1056. The material operates across a service temperature range of -40°F to 250°F and exhibits high resilience of 50%, excellent stress relaxation resistance, and low hysteresis loss. R1510 is well suited for dynamic sealing and repeated-deflection applications at moderate load levels where efficient energy return and long-term seal force retention are essential.

HyPUR-cel® R1510 is a mid-density open cell polyurethane foam in the HyPUR-cel® R-series, formulated for dynamic sealing and energy management applications where rapid force recovery after deflection is critical. At 15 pcf with a 25% Compression Deflection of 10 psi, it occupies the mid-load position in the R-series, suited for moderate-force gasketing and repeated-deflection assemblies requiring consistent contact pressure over extended service life.
The foam achieves 50% resilience per ASTM D2632 — the defining characteristic of the R-series — combined with excellent stress relaxation resistance and low hysteresis loss. These properties ensure efficient energy return between deflection cycles and sustained sealing force over time without creep. Compression set of 0.7% per ASTM D1056 confirms outstanding recovery performance. The material accepts adhesive laminations, fabrics, films, and custom coatings.
What differentiates R1510 from R1205 and R2015 within the HyPUR-cel® R-series?
R1510 operates at 15 pcf with a 25% Compression Deflection of 10 psi, compared to R1205 at 12 pcf / 5 psi and R2015 at 20 pcf / 15 psi. It is the middle load grade in the R-series, chosen when moderate sealing force is required with the high resilience and low hysteresis loss characteristics that define the series.
Why is resilience particularly important for R-series foams in dynamic applications?
Resilience measures how quickly and efficiently a foam returns energy after deflection. R-series grades achieve 45–50% resilience per ASTM D2632 — significantly higher than standard I-series foams — which translates to rapid force recovery in dynamic sealing and repeated-deflection applications where consistent contact pressure must be maintained across cycles. R1510 achieves 50% resilience per ASTM D2632.
What is the service temperature range for R1510?
R1510 is rated for continuous service from -40°F to 250°F as listed on the TDS.
Is R1510 suitable for regulated or compliance-rated environments?
No compliance standards are listed on the manufacturer's TDS for R1510. Suitability for regulated environments should be confirmed through independent testing.
How should R1510 be specified?
Specify grade (R1510), thickness, dimensional tolerances, and finished format.
