Embodiment 1
[0032] Mix the two components A and B according to the weight ratio of 1:1, the total weight is 200g, then add 0.385g of crosslinking agent and 0.05g of catalyst, mix well, degas in vacuum, and then heat at 100±5℃ for 3h to vulcanize ; Wait for it to cool down, put it in a constant temperature box at 25°C and let it stand for 24 hours at a constant temperature, and measure the penetration of the silicone gel to be 8.7mm. Take part of the gel and degas it, inject it into the outer capsule of the breast prosthesis, heat and vulcanize it, and observe its feel and elasticity after cooling.
Embodiment 2
[0034] Mix the two components A and B according to the weight ratio of 2:1, the total weight is 200g, then add 0.365g of crosslinking agent and 0.05g of catalyst, mix well, degas in vacuum, and then heat at 100±5℃ for 3h to vulcanize ; Wait for it to cool down, put it in a constant temperature box at 25°C and let it stand for 24 hours at a constant temperature, and measure the penetration of the silicone gel to be 11.59mm. Take part of the gel and degas it, inject it into the outer capsule of the breast prosthesis, heat and vulcanize it, and observe its feel and elasticity after cooling.
Embodiment 3
[0036] Mix the two components A and B according to the weight ratio of 2:1, the total weight is 200g, then add 0.375g of crosslinking agent and 0.05g of catalyst, mix well, degas in vacuum, and then heat at 100±5℃ for 3h to vulcanize ; Wait for it to cool down, put it in a constant temperature box at 25°C and let it stand for 24 hours at a constant temperature, and measure the penetration of the silicone gel to be 10.82mm.
