Which hardness is suitable for human body?

Which hardness is it appropriate to use human body? Many friends don't know this, so the silicone rubber they buy has too high hardness or too high viscosity. The following describes the characteristics of human silicone rubber and the skills of hardness selection.

For example: what we do is the face (head). Which hardness of human silicone material should we choose? It is recommended to use hardness 20 to 25 shoreA. Of course, it also depends on personal requirements. What I am talking about is the hardness used by most people at present. What about making artificial limbs (fingers)? Most friends of this product tend to be hardness 5 to 10 shoreA. If surface skin, it is recommended to be hardness 10 to 20. And the chest, hips, the whole silicone doll, silicone breast and artificial breast? Which hardness should I use? This product has some special requirements. The hand feel, softness, fluidity, curing time and so on all require very good and accurate. Therefore, this glue will not be very soft. It can be used from 0 to 5 shoreA. The usage of human silicone is not necessarily how to use. It is to use and select silicone raw materials according to different environments and parts.

Different temperatures will directly affect the speed of operation time and curing time. Uneven mixing will affect the curing effect of silicone rubber, and incorrect proportion will also affect the curing effect of silicone rubber. In short, the requirements of human silicone rubber are very strict, and problems will occur if you are careless.
