Abstract
A cushion-like shaped body () having an elastic, gel-like filling () in a thin-walled outer layer () are frequently used as seals, cushions, vibration dampers or shape compensation materials. This shaped body () is to be able to withstand severe strains, distortions, compressions and flexural forces, both in the event of brief severe stress and in the event of prolonged stress. For this purpose, the cushion-like shaped body () has a filling () of a polyurethane having Shore 000 hardness less than or equal to 80 and a compression set less than or equal to 14%, and this filling () is present within a shell having an outer layer () of a soft silicone material having a layer thickness of 0.075 to 1 mm and a Shore A hardness between 3A and 45A. Such a shaped body () is able to return to its original form without lasting elongation after tensile strain at room temperature up to 250%. There is no formation of cracks, detachment phenomena, bubbles, folds or other lasting damage. The elongation does not cause visible detachment between filling () and outer layer ().
