A rubber durometer can be used to measure the hardness of not only solid rubber but also cellular rubber (e.g. foams, sponges), plastics, and other elastomeric materials.\u00a0 There are many hardness and can be categorized dependent on the type of rubber, or application in which the method of manufacturing is formed.<\/p>\n<p>&nbsp;<\/p>\n<h2>What is Hardness?<\/h2>\n<p>\u8be5 <a href=\"https:\/\/www.nde-ed.org\/\">NDT Resource Center<\/a> defines <strong>hardness<\/strong> as the material&#8217;s <em>resistance to localized deformation<\/em>. When measured with a durometer, a steel indentor of standardized geometry is penetrated into the material with a standardized pressure. The hardness reading is then read from the gauge on a Shore scale either immediately or after a required time of penetration.<\/p>\n<p>&nbsp;<\/p>\n<h2>What is Shore Durometer?<\/h2>\n<p>Albert Ferdinand Shore invented the Shore hardness scale for the durometer in the 1920s. There are 12 different scales of Shore hardness, the most common of which is Shore A. Each Shore type is defined by their indentor shape and spring force.<\/p>\n<p>Because a durometer is measured by the indentation depth into a material &#8211; e.g. a durometer reading of 100 is when there is no penetration at all into the material, a durometer reading of 0 is when there is 0.100&#8243; (2.54 mm) or more of penetration depth &#8211; the different Shore types were invented for the different types of materials to be measured.<\/p>\n<p><a href=\"http:\/\/coirubber.com\/wp-content\/uploads\/2018\/04\/durometer-shore-applications.jpg\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-58813\" src=\"http:\/\/coirubber.com\/wp-content\/uploads\/2018\/04\/durometer-shore-applications.jpg\" alt=\"durometer-shore-applications\" width=\"609\" height=\"617\" srcset=\"https:\/\/coirubber.com\/wp-content\/uploads\/2018\/04\/durometer-shore-applications.jpg 609w, https:\/\/coirubber.com\/wp-content\/uploads\/2018\/04\/durometer-shore-applications-296x300.jpg 296w\" sizes=\"(max-width: 609px) 100vw, 609px\" \/><\/a><\/p>\n<p>\u6211\u4eec\u7684 <a href=\"http:\/\/coirubber.com\/wp-content\/uploads\/2017\/07\/COI-Durometer-Conversion-Chart.pdf\">durometer chart<\/a> gives you an idea of how the same durometer readings compare between each Shore type.
