Understanding hardness
equipment. Relative relationship between Shore hardness scales. Hardness is often one of the first criteria considered when choosing thermoplastic elastomers (TPEs). But confusion can arise when discussing hardness because of the variety of ways to measure it. Hardness is defined as a. Understanding
