Shore Hardness Explorer

Slide across the Shore A scale — or tap a material — to feel where your part should sit.

Available material: 65A Black Elastomer

Everyday anchor objects are approximate references. Schematic illustration based on a 2.5 mm Shore A measurement travel (100 points × 0.025 mm, ASTM D2240 geometry); above ~90A a Shore D durometer is normally used. This is not a durometer test and does not predict part performance — the right hardness and material for a part are confirmed at quotation.
