While other scales exist there are three commonly used shore scales in the rubber and plastics industry. The shore durometer is a device for measuring the hardness of a material typically of polymers elastomers and rubbers. The shore 00 hardness scale measures rubbers and gels that are very soft. Several batches of tires typically form with different grades of hardness within the same batch due to varying pounds and measures of the chemicals added to the mix.

For example a material with a shore hardness of 95a is also a shore 45d. Shore who developed a measurement device called a durometer in the 1920s. Lower numbers indicate less resistance and softer materials. The most effective way.

The rubber durometer chart is a scale of measuring the hardness of a rubber material developed by albert shore in the 1920s. This website is driven by the ping pong community worldwide.

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. The harder the sponge is the more speed it will give. Tires are manufactured in a rubber plant and the process consists of mixing a variety of chemicals into a large rubber block mold. The durometer scale was defined by albert f.

Generally most rubber materials fall under the rubber durometer scale of shore a. Hardness may be defined as a material s resistance to permanent indentation. The durometer hardness specifically measures an elastomer s resistance to indentation. While the rubber is used in the sport of table tennis the hardness value is just for the sponge.

Rubbers by highest sponge hardness rating view users ratings and reviews of table tennis equipment to compare products and find the right rubber blade or racket to fit your playing style. A vital sponge characteristic is the level of hardness of it.
