Inspiration Shore Hardness Rubber Chart, Shore 00 scale is used for extra soft materials whereas shore a scale is used for soft materials.

Shore hardness rubber chart. Download this shore hardness chart for a quick reference guide and comparison of scales. The shore 00 hardness scale measures rubbers and gels that are very soft. Shore a hardness scale is used for measuring the hardness of flexible mold rubbers. Shore hardness is a measure of the resistance a material has to indentation.

When selecting rubber sheet there are various thicknesses and lengths but also varying hardnesses. What is shore hardness and how is it measured. This information is provided as a selection guide only. Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials.

Shore hardness comparative chart. Here are a few examples of hardness based on durometer scale. Shore scale d on the other hand is used for rigid materials. Shore hardness chart.

As you can see from the image shore hardness 20 a corresponds to a rubber band. Approximate durometer hardness comparisons the values listed are approximate and are not to be used as an exact equivalent.

However you will find that only two of these scales are most commonly used for measuring the hardness of rubber compounds a scale for softer ones and d scale for harder ones.

Lower numbers indicate less resistance and softer materials. To elaborate on these universal scales. Durometer chart shore durometer is a scale used industry wide to measure the hardness of rubber and plastic materials. Generally most rubber materials fall under the rubber durometer scale of shore a.

Rubber band 30 shore a inner tube 55 shore a rubber tire 65 shore a rubber shoe heel 70. There are different shore hardness scales for measuring the hardness of different materials soft rubbers rigid plastics and supersoft gels for example. 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 shore a hardness scale measures the hardness of flexible mold rubbers that range in hardness from very soft and flexible to medium and somewhat flexible to hard with almost no flexibility at all.

The rubber durometer chart below gives you an idea of the rubber hardness that you want for your application. The shore durometer is a device for measuring the hardness of a material typically of polymers elastomers and rubbers. Shore hardness is measured using a durometer gauge which uses a spring loaded steel rod to compress the surface of the sample and provide a reading.
