Understanding Shore Hardness
Shore hardness is a measure of the hardness of elastomers, rubbers, and soft plastics, providing a numeric value that represents the material’s resistance to indentation. The Shore A scale, which ranges from 0 to 100, is commonly used for flexible materials like rubber. A higher Shore A value indicates a harder material, which is essential for applications requiring more durability. For instance, 50 Shore A O-rings offer a balanced combination of flexibility and strength, making them suitable for a variety of applications.
