HyPUR-cel® T1520
HyPUR-cel® T1520 is an open cell polyurethane foam with a typical density of 15 pcf (12–18 pcf tolerance) and a 25% Compression Deflection of 20 psi per ASTM D1056. The material operates across a service temperature range of -40°F to 250°F. T1520 offers a firmer compression profile than the T1515 within the same density class, with high tensile strength of 165 psi and good resilience of 36%, making it suited for higher-load cushioning and gasketing applications requiring thermoformability and dimensional stability.

HyPUR-cel® T1520 is the firmest grade in the 15 pcf HyPUR-cel® T-series density class. At a 25% Compression Deflection of 20 psi, it delivers the greatest load resistance within the class and is suited for structural cushioning, high-load gasketing, and sealing assemblies where the softer T1505 and T1515 grades would be insufficient.
The foam achieves tensile strength of 165 psi — the highest in the 15 pcf class — combined with 36% resilience per ASTM D2632 and a compression set of 2% per ASTM D1056. The thermoformable construction enables heat-shaping for complex component geometries. The material accepts laminations, fabrics, films, and custom coatings.
What differentiates T1520 from T1505 and T1515 within the same 15 pcf density class within the HyPUR-cel® T-series?
T1520 is the firmest grade in the 15 pcf density class at 20 psi Compression Deflection, compared to 15 psi for T1515 and 5 psi for T1505. It also delivers the highest tensile strength in the class at 165 psi. It is specified when maximum load resistance within the 15 pcf T-series is required.
Why is thermoformability important for T-series foam applications?
Thermoformability allows the foam to be heat-shaped into contoured or three-dimensional configurations. This is particularly valuable in automotive interior trim, ergonomic cushioning components, and complex-geometry sealing assemblies where flat sheet material cannot achieve the required form. All T-series grades including T1520 are thermoformable as stated on the TDS.
What is the service temperature range for T1520?
T1520 is rated for continuous service from -40°F to 250°F as listed on the TDS.
Is T1520 suitable for automotive flammability-regulated environments?
No flammability compliance standard is listed on the manufacturer's TDS for T1520. Suitability for flammability-regulated environments should be confirmed through independent testing.
How should T1520 be specified?
Specify grade (T1520), thickness, compliance requirements if applicable, dimensional tolerances, and finished format.
