Factors affecting the selection of silicone hardness for sex toys

Factors affecting the selection of silicone hardness for sex toys
Simulation requirements
Products that pursue high simulation (such as reverse molds and real dolls) usually use 10-30 degrees of soft silicone to simulate the soft touch and elasticity of real skin.
Some products will be designed in layers (such as outer soft silicone + internal hard skeleton), taking into account both touch and structural stability.
Functional positioning
Stimulation products (such as vibrators and massagers): mostly use 20-40 degrees, which not only ensures the comfort of contact with the skin, but also provides sufficient support to transmit vibration.
Insertable products (such as anal plugs and urethral stimulators): The hardness may be higher (30-50 degrees), which is convenient for precise control of insertion depth and stability.
Safety and durability
Silicone with too low hardness (such as 0 degrees) may be easy to deform and tear, and needs to be matched with an internal support structure;
Silicone with too high hardness (such as above 60 degrees) may lack ergonomic adaptability and needs to be used with lubricants.
