Rubber hardness determines the playing characteristics of table tennis blades (or paddles). However, depending on the manufacturer, hardness is measured on different Shore durometer scales. This Demonstration provides a conversion chart for the common durometer scales, so that different measures of rubber hardness can be converted and compared. A table for both topsheet and sponge for the common table tennis blades is given in the rubber hardness list.

Details

The Shore A scale is used for testing soft elastomers (rubbers) and other soft polymers. Hard elastomers and most other polymer materials (thermoplastics and thermosets) are measured on the Shore D scale. Chinese table tennis rubbers are normally measured on the Shore A scale, while the rubbers from European factories are measured on the Shore O scale. One can use the "hardness conversion" tab to convert from several Shore scales, while the "rubber hardness list" provides the hardness of both topsheet and sponge of table tennis rubber on the desired scale. For example, a European table tennis rubber with a 50 hardness degree (Shore O) is equivalent to a 37–38 hardness degree Chinese table tennis rubber (Shore A).
