HyPUR-cel® S0702
HyPUR-cel® S0702 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 exceptionally high elongation of 340% combined with low compression set. S0702 is thermoformable and well suited for applications requiring a highly conformable, low-force foam with excellent stretch, shape recovery, and dimensional stability over a broad temperature range.

HyPUR-cel® S0702 is an open cell polyurethane foam in the HyPUR-cel® S-series, offering a soft compression profile at 7 pcf with a 25% Compression Deflection of 2 psi. It is designed for low-force gasketing, conformable sealing, and thermoformed cushioning applications requiring exceptional stretch and shape recovery across a wide temperature range including cryogenic service.
The foam achieves 340% elongation per ASTM D3574 — among the highest in the S-series — enabling it to conform over irregular and complex geometries without tearing. Compression set of 2.5% per ASTM D1056 supports long-term seal retention after deflection. Tensile strength of 100 psi provides good fabrication characteristics for converted component production. The thermoformable construction enables heat-shaping into contoured parts. The material accepts laminations, fabrics, films, and custom coatings.
What differentiates S0702 from S0701 within the HyPUR-cel® S-series?
S0701 and S0702 share identical published specification values — both at 7 pcf, 2 psi Compression Deflection, and 340% elongation — and are distinct grades within the same performance envelope. If your application requires differentiation between these two grades, contact H-O Products for guidance on which is appropriate for your specific end-use.
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. S0702 is thermoformable as stated on the TDS.
What is the service temperature range for S0702?
S0702 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 S0702 suitable for regulated or compliance-rated environments?
No compliance standards are listed on the manufacturer's TDS for S0702. Suitability for regulated environments should be confirmed through independent testing.
How should S0702 be specified?
Specify grade (S0702), thickness, dimensional tolerances, and finished format.
