Abstract (en)
[origin: EP0914966A1] The elastomer layer (4) is made slightly compressible by including a large number of cavities produced by microspheres (5). These are pre-expanded or are expanded inside the elastomer material e.g. by containing a solvent which expands at a temperature of 100 - 150 degrees C. The content of microspheres in the material is between 0.5 and 10 percent by weight and preferably 2 - 4 percent, while their diameter is between 10 and 30 microns. The thickness of the elastomer layer, which is in the form of a sleeve, is less than 0.7 mm and preferably 0.3 mm or less. In a variant the cavities can be created by chemical expansion of an elastomer layer during hardening.
