Leveraging the open-cell, breathable, low density features of XPF, applications fall into two categories: protective equipment, and orthotic - prosthetic medical devices.
Protective equipment for sports, military and first responder applications would benefit from the dramatically improved impact protection that XPF provides. Compared to equivalent conventional polyurethane foam, our auxetic foam provides over 6 time better impact protection while allowing creaseless concave and convex forming. Ideal applications include helmets, footwear, elbow pads, knee pads, hip pads, shin pads, chest protectors, shoulder pads, arm pads and gloves. Design alternatives include equivalent protection with reduced weight and bulk and/or improved protection with reduced weight in the same three- dimensional shape as existing padding.
Orthotic and prosthetic medical devices would benefit from XPF’s ability to provide a constant pressure, pinch-point free solution capable of autonomously responding to swelling and inflammation. Across the clinical spectrum of supportive and protective braces and associated devices, inflammation causing volumetric changes of +/- 20% are typical. XPF’s unique auxetic properties provide autonomous and opposite volumetric changes with responsiveness of up to +/- 50%. As the injury swells, imposing a compressive stress on the device pad, XPF pads shrink providing a constant clinically desirable level of support without pressure points. Devices with conventional padding further agrivate inflammatory conditions, and are prone to pressure points and need constant patient adjustment. Ideal applications include prosthetic socks, orthotic braces, AFO’s, neck braces, walking boots, soft casts and post-operative braces.
