How soft can liquid silicone be?

Liquid silica gel is a kind of organic silicone material. It is a platinum-based liquid silica gel. After the two components AB are mixed and solidified at a ratio of 1:1, the transparent state is soft and resilient. It is also called jelly glue. Silicone gel liquid is characterized by low viscosity and strong fluidity, and the material has passed the EU FDA food-grade contact certification. It is environmentally friendly, non-toxic and odorless. It is widely used for filling precision components, electronic appliances, filters, instruments, auxiliary materials, chest pads, etc. Potting. It can be operated manually or by machine, and it can be cured at room temperature and quickly cured by heating.
So, how soft can liquid silicone be? Common silicone gel itself is very soft, its softness is close to human skin, or even softer. It is impossible to measure the hardness of silicone rubber with the Shore A type unit commonly used, and even the Shore C type unit is difficult to measure. Generally speaking, it is particularly soft. Another feature is that the surface of the silicone gel is self-adhesive after curing. If there is no material to wrap it, it will be sticky. For example, when making silicone gel bra patches, they are usually wrapped with TPU film.
