Rubber with shore hardness 50
WebbThis document specifies a method for determining the indentation hardness (Shore hardness) of vulcanized or thermoplastic rubber using durometers with the following scales: — the A scale for rubbers in the normal-hardness range; — the D scale for rubbers in the high-hardness range; WebbThe Shore A Hardness scale is one such unit of measurement, use to determine the hardness of flexible rubbers and elastomers. The scale ranges from extremely pliable to hard with almost no flexibility at all. In general, the higher the Shore A Hardness, the harder a material will be. As an example, a rubber band would have a Shore A Hardness of ...
