WebThe thermodynamic properties of an elastomer can be understood in terms of what happens to these cross-linked networks as the bulk material is stretched from its relaxed state.

WebOutstanding mechanical properties, ... A related phenomenon can easily be demonstrated by hanging a weight on a strip of unfilled rubber such as that used for elastic bands. If the strip is heated using a hot air blower, the weight will rise, i.e. contrary to expectations, the strip will get shorter, and this is known as the Gough-Joule effect. ... WebRubber elasticity refers to a property of crosslinked rubber: it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length. This can be repeated many times with no apparent degradation to the rubber. Rubber is a member of a larger class of materials called elastomers and it is difficult to …
