Rubber hardness chart
WebbHere is a rubber temperature chart that provides high and low temperature ranges for all popular rubber materials. The closer that your material is to the limit of your rubber temperature range, the faster the material will degrade. Also, notice that Silicone has high rubber temperature resistance and also great low rubber temperature resistance. WebbRubber hardly ever slides on other rubber like materials but on tracks grossly dissimilar from it in surface texture, chemical constitution and elastic behavior, ... macroscopic mechanical properties such as tensile strength, elongation at break, hardness etc. Thomas (Thomas, 1958, 1974) proposed the problem of abrasion is presented using
