SpletShore D uses a sharp conical point for its indenter tip and a higher stiffness spring to make it ideal for testing harder polymers such as cured epoxies or highly cross-linked … SpletThe Shore A scale is used for measuring the hardness of softer, more flexible materials. Shore A “0” denotes extremely soft, gel like materials such as silicones, while semi-rigid plastics will be measured at the highest end of the scale around 90-95A. 90 Shore A materials are suited to machining compared to softer materials that can be ground. j b g thomas
