Hapco uses comprehensive Shore hardness durometer charts and comparisons to help clients select the right materials for their project.

The Shore A hardness scale is an essential tool for assessing the resistance of materials, particularly polymers, to localised deformation or indentation. This scale, which ranges from 0 to 100, is …

The Shore A Hardness Scale measures the hardness of flexible mold rubbers that range in hardness from very soft and flexible, to medium and somewhat flexible, to hard with almost no flexibility at all.

Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials.

Feb 27, 2025 · The Shore hardness conversion table listed below is for the convenience of people to discuss these materials and have a common reference point. Note: The hardness values listed below …

The values in the table are approximate and provide a general guide for comparing different Shore hardness scales. Different materials with the same Shore hardness can feel different due to other …

May 24, 2023 · Shore A durometers range from 0 to 100 — the higher the durometer value, the harder the material. The Shore A scale is often used in the polymer industry to aid in material selection, …
