THE FOAM FOR RESPONSIVE ENERGY RETURN
R-Series: Engineered for stable energy return and long-term resiliency
R-Series suits applications where long-term performance under repeated cyclic compression is critical. Instead of relying on pneumatic response for resiliency, R-Series is engineered with an elastomeric structure that maintains stellar cellular and dimensional integrity through 1M+ cycles at 50% compression — reducing material fatigue while improving product reliability in demanding, repetitive compression applications.
REDUCED DEGRADATION OVER TIME
Consistent performance across product lifecycle
As an open-cellular polyurethane foam designed for controlled response under repeated loads, R-Series doesn’t rely on the pneumatic rebound for resiliency that is characteristic of closed-cell polymer foams. This provides uniquely responsive recovery and robust energy return, culminating in very low hysteresis loss and long product life.
10-25 pcf densities
Varying firmness and color options to choose from, including designing your own.
Maximum energy return
Low hysteresis loss validated by cyclic compression fatigue resistance.
Design versatility
Resilient material behavior supports many performance and application needs.
Cost efficiency
Extended performance reduces costly replacement frequency.
PREDICTABLE PERFORMANCE WITHOUT TRADE-OFFS
Dynamic cyclic compression response
R-Series maintains a controlled, repeatable response under cyclic loading for consistent energy return and recovery across a range of densities and firmness options. Its dimensional and firmness stability reduces rebound variability during compression and recovery over your product’s lifecycle. In dynamic applications, R-Series enables more predictable performance without compromising firmness, durability and responsiveness.
R IS FOR RESILIENCY
Ideal for footwear, sporting goods and die cutting
R-Series excels in applications that demand consistent performance under repeated compression. It maintains its energy return and structural integrity through continuous use, helping reduce variability in dynamic environments. This makes it a reliable choice for products designed for long-term responsiveness and durability.
hyPURcel R-Series property sheets
Available in rolls and sheets with custom widths up to 62” wide and splice-free lengths up to 100’, skived to your required gauge. hyPURcel foams can be enhanced with functional additives such as antimicrobial, fire retardants, antioxidants and UX stabilizers. Value-added finishing processes include PSA, film, slitting, sheeting and fabric laminations. Custom color matching is also available.
Understanding hyPURcel naming conventions: The first two digits indicate density (lbs/ft3), and the last two indicate compression deflection (psi) per ASTM standards.
