HyPUR-cel® T1515
HyPUR-cel® T1515 is an open cell polyurethane foam with a typical density of 15 pcf (12–18 pcf tolerance) and a 25% Compression Deflection of 15 psi per ASTM D1056. The material operates across a service temperature range of -40°F to 250°F and achieves a flammability pass rating per FMVSS-302 at 0.063″ or thicker. T1515 delivers high tensile strength of 130 psi with low compression set of 1.6%, making it well suited for demanding cushioning, sealing, and gasketing applications requiring thermoformability, structural integrity, and long-term dimensional stability.

HyPUR-cel® T1515 is the mid-firmness grade in the 15 pcf HyPUR-cel® T-series density class. At a 25% Compression Deflection of 15 psi, it is designed for demanding cushioning, sealing, and gasketing applications where moderate-to-firm load resistance, thermoformability, and FMVSS-302 compliance at the tighter 0.063″ threshold are all required.
The foam achieves tensile strength of 130 psi and compression set of 1.6% per ASTM D1056 — the lowest compression set value in the 15 pcf class — supporting strong shape recovery after sustained deflection. Tear strength of 145.5 lb./in is as listed on the H-O Products TDS. The material accepts laminations, fabrics, films, and custom coatings.
What differentiates T1515 from T1505 and T1520 within the same 15 pcf density class within the HyPUR-cel® T-series?
T1515 delivers a 25% Compression Deflection of 15 psi at 15 pcf — firmer than T1505 at 5 psi and softer than T1520 at 20 psi. It is also the only 15 pcf T-series grade with FMVSS-302 compliance at 0.063" (versus 0.079" for T1505), making it the appropriate choice when both moderate firmness and a tighter flammability thickness threshold are 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 T1515 are thermoformable as stated on the TDS.
What is the service temperature range for T1515?
T1515 is rated for continuous service from -40°F to 250°F as listed on the TDS.
Is T1515 suitable for automotive flammability-regulated environments?
Yes. T1515 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 T1515 be specified?
Specify grade (T1515), thickness, compliance requirements if applicable, dimensional tolerances, and finished format.
