Abstract
A resilient protective wrap usable to wrap a body part of a user for protection against injury includes at least one resilient fabric layer that is stretchable at least in one direction, and an open cell water-based polyurethane foam laminated on the resilient fabric layer and made from a material including an aqueous dispersion of polyurethane. The polyurethane foam has a thickness of at least 1 mm, a largest elongation ranging from 200%-450%, a modulus of elasticity ranging from 2 to 7 kgf/cm2, a tensile strength of at least 4 kgf/cm2, and a density ranging from 180-600 g/l.
