Soft-flexible
Like a soft eraser. Mould and prosthetic silicones.
Feroca Materials
What does the Shore scale measure?
Shore 00
For very soft materials: gels, soft foams, prosthetic silicones. Equivalent to Shore A but shifted 50 units towards softer materials.
Shore A
The most widely used scale for silicones and rubbers. Covers from mould gels (A10–A20) to technical rubbers (A70–A90). A typical silicone mould is A25–A40.
Shore D
For rigid materials: polyurethane resins, epoxy and technical plastics. From D60 onwards, the material behaves like a hard plastic.
Overlap zones
The three scales overlap: there are materials that can be described on two different scales. The bar positions are a indicative visualization — exact equivalences depend on the material type and are not linear. For precise conversions, refer to the ASTM D2240 tables.
