HyPUR-cel® V0575
HyPUR-cel® V0575 is a viscoelastic open cell polyurethane foam with a density range of 4 – 7 pcf and an IFD 25% range of 65 – 85 lbs per ASTM D3574. The material delivers very low resilience of 5.6% combined with exceptional compression fatigue resistance and 190% elongation, operating across a service temperature range of -40°F to 250°F. V0575 is well suited for high-firmness body-contact cushioning, impact protection, and pressure management applications requiring slow force recovery and long-term performance under repeated deflection.

HyPUR-cel® V0575 is a high-firmness viscoelastic open cell polyurethane foam engineered for body-contact cushioning, impact protection, and pressure management applications where elevated support and long-term durability are critical. Its 65 – 85 lb IFD places it well above the firmer V0542 and at the upper end of the 5 pcf-class HyPUR-cel viscoelastic range, while very low resilience of 5.6% preserves slow force recovery in body-contact use.
The material is distinguished by exceptional compression fatigue resistance, which supports sustained performance under repeated deflection — making it well suited for high-cycle applications such as seating cushions, repeated-impact protective assemblies, and pressure-loaded ergonomic components.
The open cell structure allows air and moisture passage, the foam offers 190% elongation for conformable fit, and V0575 remains dimensionally stable across a service temperature range of -40°F to 250°F. The foam is available with adhesives, laminated films, fabrics, and custom coatings.
What differentiates V0575 from softer grades in the HyPUR-cel viscoelastic family?
V0575 is the high-firmness viscoelastic foam in the 5 pcf-class HyPUR-cel range, with a 65 – 85 lb IFD well above V0542 (42 lbs) and substantially firmer than V0533 (33 lbs) or V0525 (25 lbs). Beyond elevated firmness, V0575 is differentiated by exceptional compression fatigue resistance, which sustains performance under repeated deflection where lower-IFD grades would degrade.
Why is compression set critical for viscoelastic cushioning foams?
Compression set measures the permanent deformation a foam retains after sustained compression and directly indicates how well a cushion will hold its shape over service life. V0575's 3% max compression set per ASTM D1056, combined with exceptional compression fatigue resistance, supports long-term performance in high-firmness cushioning and impact assemblies subjected to repeated loading cycles.
What is the service temperature range for V0575?
-40°F to 250°F.
Is V0575 suitable for regulated environments?
No compliance standards are specified on the manufacturer's TDS for V0575. End users requiring flammability, medical, automotive, or other regulatory qualification should request supporting documentation from H-O Products for the specific application.
How should V0575 be specified?
Specify grade (V0575), thickness, compliance requirements, dimensional tolerances, and finished format.
