Because the softness, color and feel of silica gel are very close to human skin, the preferred material for these DTYs is liquid silicone, but the liquid mold silica gel is divided into additive gel and condensation gel. I don’t know which ones are more. Suitable for contact with the skin!

The viscosity of the rubber before vulcanization is lower, which is convenient for perfusion. It does not exotherm during vulcanization, no low molecular by-products are released, the shrinkage rate is small, the vulcanization can be deep, and the operation is simple. After vulcanization, it becomes a soft, transparent or translucent elastomer that retains its elasticity over a long period of time at temperatures ranging from -65 to 200 °C. Excellent electrical and chemical stability, water resistance, ozone resistance, radiation resistance, weathering resistance, moisture resistance, shock resistance, good low compression set, low combustion; physiologically inert, non-toxic, odorless, and vulcanized Speed can be controlled with temperature and so on.

The condensation type silica gel generally consists of five components of a base rubber, a crosslinking agent, a catalyst, a filler and an additive. Usually, the base rubber, the crosslinking agent and the filler are made into one component, and the catalyst is used as a single component, so the mold silicone is used. Also known as two-component vulcanized silica gel, RTV-2 room temperature curing silica gel. The vulcanization is carried out at room temperature, and an appropriate amount (1% to 5%) of a catalyst (curing agent) is added to the main rubber component to form a crosslinking reaction to form a flexible, elastic colloid.

Both silicones have their own characteristics, but for the sake of arrangement, if the silicone needs to be applied to the mold or directly contact with the skin, it is recommended to use the addition of silicone. The addition of silicone is also called FDA certification. Silicone that can be in contact with food!
