What is the reason for the tension difference in the mold silicone

What is the reason for the tension difference in the mold silicone, I believe many customers may have such confusion. Next, we will analyze the reasons for the poor tension of the mold silicone.
In the process of making molds, many operators add a large amount of silicone oil to the silicone in order to reduce its viscosity and make it easier to operate. This makes the silicone very soft, the product not resistant to pulling, the tear strength decreases, and the tensile strength deteriorates. As a result, the mold is not durable, has a short service life, and the number of mold turns is reduced.
Here, the editor of HANAST added a little knowledge that the mold silica gel itself does not emit oil, which is due to the addition of composite silicone oil (a complex of silicone oil and white mineral oil) in the operation process, because white mineral oil is a Petrochemical, not silicone oil.
