Thus if you need a rubber or o ring durometer that feels like a running shoe sole review our rubber hardness chart below then pick shore 70a. It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken. The main topics of interest in topology are the properties that remain. For example a square can be deformed into a circle without breaking it but a figure 8 cannot.

Rubber sheet geometry noun a humorous name for topology. Concept of topology rubber sheet geometry topology does not distinguish between a circle and a square but it does between a circle and a figure eight. A sheet of rubber especially one from which shapes can be cut or which is used to protect against water dirt etc. Generally most rubber materials fall under the rubber durometer scale of shore a.

A rubber durometer of shore 70a is the most commonly chosen material hardness for all applications. Hence a square is topologically equivalent to a circle but different from a figure 8.
