Product Description
Why does the silicone mould appear to be dry outside but wet inside?
Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.
Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it.
Why is the tear strength of silicone molds weak?
There are three reasons:
1) In order to reduce the viscosity of silicone rubber and pursue good quality, a large amount of silicone oil can be added to the silicone rubber when making the mold. In fact, it may have the opposite effect. The addition of silicone oil can severely reduce tension and tear strength. And the silicon mold will be in a fragile and fragile state.
2) too much catalyst may be added to the silicone rubber, we recommend that customers add catalyst no more than 5%, 2% is fine.
3) After the silicone mold is finished, you may use it prematurely. We recommend that customers start using the mold after 24 hours. More importantly, it would be better if you could make an outer mold to protect the silicone mold.
Why does the mold silicone have poor tension?
In the process of making the mold, in order to reduce the viscosity of the silicone rubber and make the silicone rubber easy to operate, a large amount of silicone oil is added to the silicone rubber, which will make the silicone rubber very soft, resulting in poor tensile strength and reduced tear strength. The phenomenon of poor tensile force, resulting in the phenomenon that the mold is not durable, the service life is short, and the number of mold overturns is small.
