HyPUR-cel® S0601
HyPUR-cel® S0601 is an open cell polyurethane foam with a typical density of 7 pcf (5.5–8.5 pcf tolerance) and a 25% Compression Deflection of 2 psi per ASTM D1056. The material operates across an extended service temperature range of -67°F to 250°F and exhibits 130% elongation combined with low compression set. S0601 is thermoformable and suited for conformable sealing, cushioning, and gasketing applications where soft, flexible foam with excellent low-temperature performance and dimensional stability are required.

HyPUR-cel® S0601 is an open cell polyurethane foam in the HyPUR-cel® S-series, offering a slightly firmer compression profile than the S0501 at 7 pcf density and 2 psi Compression Deflection. It is designed for conformable sealing, cushioning, and gasketing applications requiring a soft but structurally supported foam with excellent low-temperature performance and thermoformability.
The foam delivers 130% elongation per ASTM D3574, allowing good conformability over complex surfaces, and achieves a compression set of 2.5% per ASTM D1056 — tighter than S0501 — supporting long-term seal retention. Tensile strength of 90 psi and tear strength of 14.4 lb./in provide strong fabrication characteristics for converted component applications.
The extended service temperature range of -67°F to 250°F makes it suitable for low-temperature and cryogenic sealing environments. The material is thermoformable and accepts laminations, fabrics, films, and custom coatings.
What differentiates S0601 from S0501 within the HyPUR-cel® S-series?
S0601 offers a 25% Compression Deflection of 2 psi at 7 pcf density — firmer and denser than S0501 at 1 psi / 5 pcf — with lower elongation (130% vs. 325%). S0601 is chosen when slightly more structural resistance is needed than S0501 provides, while retaining thermoformability, low compression set, and the extended low-temperature service range of the S-series.
Why is thermoformability important for S-series foam applications?
Thermoformability allows the foam to be heat-shaped into contoured or three-dimensional configurations without adhesive lamination or complex tooling. This is particularly valuable in body-contact cushioning, automotive soft-touch components, and conformable sealing assemblies where a flat sheet cannot achieve the required geometry. S0601 is thermoformable as stated on the TDS.
What is the service temperature range for S0601?
S0601 is rated for continuous service from -67°F to 250°F as listed on the TDS. The lower limit of -67°F distinguishes the S-series from standard I-series grades and makes it suitable for cryogenic and low-temperature environments.
Is S0601 suitable for regulated or compliance-rated environments?
No compliance standards are listed on the manufacturer's TDS for S0601. Suitability for regulated environments should be confirmed through independent testing.
How should S0601 be specified?
Specify grade (S0601), thickness, dimensional tolerances, and finished format.
