HyPUR-cel® T1505
HyPUR-cel® T1505 is an open cell polyurethane foam with a typical density of 15 pcf (12–18 pcf tolerance) and a 25% Compression Deflection of 5 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 0.079″ or thicker. T1505 offers a soft compression profile at higher density with 220% elongation, making it suited for conformable sealing and cushioning applications where low sealing force, thermoformability, and long-term dimensional stability are required.

HyPUR-cel® T1505 occupies a unique position in the HyPUR-cel® T-series — it delivers the softest compression profile in the 15 pcf density class at just 5 psi Compression Deflection, combining high density with low touch force and 220% elongation for conformable sealing and cushioning applications where structural mass is required but minimal compression resistance is desired.
The foam achieves a compression set of 1.8% per ASTM D1056, supporting long-term shape retention after deflection. Elongation of 220% provides good conformability for thermoformed component geometries. FMVSS-302 compliance at 0.079″ or thicker makes it suitable for automotive interior environments. The material accepts laminations, fabrics, films, and custom coatings.
What differentiates T1505 from T1515 and T1520 within the same 15 pcf density class within the HyPUR-cel® T-series?
T1505 is the softest grade in the 15 pcf density class at 5 psi Compression Deflection — significantly softer than T1515 at 15 psi and T1520 at 20 psi. It is the appropriate choice when high density is required for structural or mass reasons but low sealing force and conformability are the primary mechanical design criteria.
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 T1505 are thermoformable as stated on the TDS.
What is the service temperature range for T1505?
T1505 is rated for continuous service from -40°F to 250°F as listed on the TDS.
Is T1505 suitable for automotive flammability-regulated environments?
Yes. T1505 achieves a pass rating per FMVSS-302 at 0.079" or thicker, making it suitable for automotive interior applications subject to Federal Motor Vehicle Safety Standards flammability requirements.
How should T1505 be specified?
Specify grade (T1505), thickness, compliance requirements if applicable, dimensional tolerances, and finished format.
