HyPUR-cel® T0820
HyPUR-cel® T0820 is an open cell polyurethane foam with a typical density of 8 pcf (6.5–9.5 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. T0820 offers the firmest compression profile in the 8 pcf T-series density class, delivering high tensile strength of 124 psi with good resilience of 38%, suited for applications requiring elevated load-bearing capacity with thermoformability and dimensional stability.

HyPUR-cel® T0820 is the firmest grade at the 8 pcf density level in the HyPUR-cel® T-series. At a 25% Compression Deflection of 20 psi, it provides the highest load resistance within the 8 pcf class and is designed for structural cushioning, high-load gasketing, and sealing applications where the softer T0805 and T0812 grades would be insufficient.
The foam delivers tensile strength of 124 psi — the highest in the 8 pcf T-series — combined with 38% resilience per ASTM D2632 and a compression set of 4.2% per ASTM D1056. The thermoformable construction enables heat-shaping for complex component geometries. The material accepts laminations, fabrics, films, and custom coatings.
What differentiates T0820 from T0805 and T0812 within the same 8 pcf density class within the HyPUR-cel® T-series?
T0820 is the firmest grade in the 8 pcf T-series density class at 20 psi Compression Deflection, compared to 12 psi for T0812 and 5 psi for T0805. It also delivers the highest tensile strength in the class at 124 psi. It is specified when maximum load-bearing capacity within the 8 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 T0820 are thermoformable as stated on the TDS.
What is the service temperature range for T0820?
T0820 is rated for continuous service from -40°F to 250°F as listed on the TDS.
Is T0820 suitable for automotive flammability-regulated environments?
No flammability compliance standard is listed on the manufacturer's TDS for T0820. Suitability for flammability-regulated environments should be confirmed through independent testing.
How should T0820 be specified?
Specify grade (T0820), thickness, compliance requirements if applicable, dimensional tolerances, and finished format.
