There are two most common Durometer scale, Shore A for flexible elastomers(range in hardness from very soft to medium, and to hard with almost no flexibility at all.) and Shore D for hard elastomers(hard rubbers, hard plastics). Before producing silicone items, It is very important to select the correct shore hardness of liquid silicone for different applications.
Shore A 0-degree application: it can be used for filling mould of super-soft silicone rubber mold, making of imitation prosthesis, such as mask, penis, sex articles, silicone rubber sheet, making of the soft gasket.
Shore A 5-degree application: it can be used for filling mold of super soft silica gel mould, making hand-made soap and candle silica gel mould, making imitation prosthesis products, such as mask, penis, sex articles, and silica gel sheet, making soft gasket products.
Shore A 10-degree application: can be used for soft silica gel mold filling mold production; hand soap, candle silica gel mold production; simulation of the production of prosthetic products, such as silica gel hands, feet, masks, penis, sex products, silica gel sheet, and soft gasket production.
Shore A 15-degree application: can be used for soft silicone mold filling mold production; hand soap, candle silicone mold production; simulation of the production of prosthetic products, such as silicone hand, foot, mask, penis, sex products, silicone skin, and soft gasket production.
Shore A 20-degree application: can be used for food-grade candy chocolate mold or single mold manufacturing; epoxy, polyester resin, polystyrene, vinyl plastic, paraffin wax, and other materials mold; Small cement components, cultural stone, concrete, gypsum, and other products of mold manufacturing; 3d printing mold production, candle manual soap pouring mold production; mechanical properties of waterproof sealing use.
Shore A 25-degree application: can be used for food-grade candy chocolate mold or single mold manufacturing; epoxy, polyester resin, polystyrene, vinyl plastic, paraffin wax, and other materials mold; Small and medium-sized cement components, cultural stone, concrete, gypsum, and other products of mold manufacturing; 3D printing model production, candle manual soap pouring mold production.
Shore A 30-degree application: can be used for metal crafts, alloy car and other precision mold manufacturing; epoxy, polyester resin, polystyrene, vinyl plastic, paraffin, and other materials mold; Large cement components, cultural stone, concrete, gypsum, and other products of mold manufacturing; high-precision hand plate model design, rapid prototyping design; used in vacuum bag multi-mold spraying class production.
Shore A 40-degree application: can be used for metal crafts, alloy car, and other precision mold manufacturing, as well as fixture protection; epoxy, polyester resin, polystyrene, vinyl plastic, paraffin, and other materials mold; Large cement components, cultural stone, concrete, gypsum, and other products of mold manufacturing; high-precision hand plate model design, rapid prototyping design; lost wax casting process of silicone mold production; product measurement reference production.
Shore A 50-60 degree application: can be used for metal crafts, alloy car, and other precision mold manufacturing, as well as fixture protection; epoxy, polyester resin, polystyrene, vinyl plastic, paraffin, and other materials mold; Large cement components, cultural stone, concrete, gypsum, and other products mold manufacturing; high-precision hand plate model design, rapid prototyping design; product measurement reference production.
The hardness described above is only for the most extensive use. For special uses, it is important to know the part or product that you will be molding clearly.
