1. A compression product comprising an elastic component or material, the elastic component or material having a delayed continuous relaxation behavior, the elastic material being capable of applying a compression or a supporting force or a local pressure to a part of the body of a subject, the elastic material furthermore being capable of passing through a first phase during which the material is expanded, a second phase during which the component or material relaxes without recovering its original shape, and a third phase during which the component or material recovers its original shape with successive deceleration, wherein relaxation is self-initiated in the absence of an external stimulus,
wherein the relaxation behavior is delayed in time as compared to an elastic component or material not containing N-diol,
wherein the elastic component or material comprises:
(a) a non-quaternized polyurethane (PU) polymer containing N-diol (PU-N);
and/or
(b) a quaternized polyurethane (PU) polymer or ionomer containing quaternized N-diol (PU-N+);
and, optionally,
(c) elastane.
