HyPUR-cel® S1005
HyPUR-cel® S1005 is an open cell polyurethane foam with a typical density of 10 pcf (8–12 pcf tolerance) and a 25% Compression Deflection of 5 psi per ASTM D1056. The material operates across an extended service temperature range of -67°F to 250°F and exhibits high elongation of 305% and strong tensile strength of 140 psi combined with low compression set. S1005 is thermoformable and suited for applications requiring a higher-density conformable foam with excellent stretch, structural integrity, and dimensional stability across a wide temperature range.

HyPUR-cel® S1005 is a mid-density open cell polyurethane foam in the HyPUR-cel® S-series, positioned between the lower-density 7 pcf grades and the higher-density 12 pcf grades. At 10 pcf with a 25% Compression Deflection of 5 psi, it delivers greater structural support than the softer S-series grades while retaining excellent conformability and the extended low-temperature service capability that characterizes the series.
The foam achieves 305% elongation per ASTM D3574 and tensile strength of 140 psi — the highest tensile value among the single-typical-value S-series grades — providing strong fabrication performance alongside exceptional stretch. Compression set of 2% per ASTM D1056 confirms good shape retention after deflection. The thermoformable construction allows heat-shaping for contoured applications. The material accepts laminations, fabrics, films, and custom coatings.
What differentiates S1005 from lower-density S-series grades at 7 pcf within the HyPUR-cel® S-series?
S1005 operates at 10 pcf density and 5 psi Compression Deflection — firmer and denser than the 7 pcf S-series grades (S0601, S0701, S0702) — with the highest tensile strength (140 psi) among the single-value S-series grades. It is the appropriate choice when greater structural integrity is needed alongside the thermoformability and extended low-temperature performance 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. S1005 is thermoformable as stated on the TDS.
What is the service temperature range for S1005?
S1005 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 S1005 suitable for regulated or compliance-rated environments?
No compliance standards are listed on the manufacturer's TDS for S1005. Suitability for regulated environments should be confirmed through independent testing.
How should S1005 be specified?
Specify grade (S1005), thickness, dimensional tolerances, and finished format.
