Durometer shore hardness scale.

Rubber durometer scale. Style 1 testers can be held in your hand or mounted to a stand with the included knob. Approximate durometer hardness comparisons the values listed are approximate and are not to be used as an exact equivalent. The rubber durometer chart below gives you an idea of the rubber hardness that you want for your application. They can be held in your hand or mounted to a stand with the included knob.

Shore in the 1920 s. Here are a few examples of hardness based on durometer scale. Generally most rubber materials fall under the rubber durometer scale of shore a. The shore durometer is a device for measuring the hardness of a material typically of polymers elastomers and rubbers.

A durometer scale also called a shore hardness scale and rubber hardness scale was created so people can have a point of reference to compare different materials such as soft rubbers rigid plastics gels and other non metallic materials. As time progressed multiple durometer scales were created. The shore durometer scales that are most commonly used in plastics rubber and silicone are the a d and 00 shore scales. Understanding shore s durometer hardness scale can create a world of difference when picking out material as the ratings will always tell you how hard flexible and resilient each rubber is.

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. Originally the result was just signified by a number for example 50 durometer. A chart showing general hardness comparisons is below. The durometer scale was defined by albert f.

These scales were invented so that people can discuss these materials and have a common point of reference. Shore who developed a measurement device called a durometer in the 1920s. There are different shore hardness scales for measuring the hardness of different materials. For more information about durometer scales please see the bottom of about rubber.

For example you would not choose a rubber with a durometer of 70a to make a mold of a plaster standing. Lower numbers indicate less resistance and softer materials. The shore durometer scale was created by albert f. Hardness is an important consideration in sealing materials.

Hardness may be defined as a material s resistance to permanent indentation. Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. This information is provided as a selection guide only. Durometer measures the hardness in polymers elastomers and rubbers.

Rubber band 30 shore a inner tube 55 shore a rubber tire 65 shore a rubber shoe heel 70. When selecting rubber sheet there are various thicknesses and lengths but also varying hardnesses. Remember that the higher the rating the harder and less pliable the rubber material will be compared to elastomers with a lower durometer rating.
