*depending on curing agent quantity
Shore 0-20
Very soft silicones with very high flexibility. Suitable for moulds with pronounced undercuts.
Shore 20-40
Medium-hard silicones. The most common materials for impressions with undercuts and good dimensional stability.
Shore 40-80
Hard silicones. For self-supporting moulds, vacuum casting resins, and rapid prototyping.
Shore Hardness A scale - comparison table

Highly flexible moulds made of silicone rubber allow the reproduction of complicated moulded parts with undercuts. The main areas of application are, for example, the production of model parts, furniture ornaments, relief images, decorative candles, architectural models, decorative buttons, doll bodies, sealing profiles as well as reproductions in monument conservation.
Master models made of the usual materials such as wood, metal, plastic, plaster, stone, and wax are well suited for impressions with silicone rubber. All silicones are self-releasing, no release agent is required. More information on the product.
