Silicone molds are made from silicone as the raw material, and regardless of the type of silicone mold, there is a slight degree of shrinkage. The degree of index shrinkage varies, and shrinkage does not affect products that are not very precise, as the degree of shrinkage is very small.
Silicone molds include molds made of industrial grade silicone and molds made of food grade silicone. The degree of shrinkage varies depending on their type. Industrial grade silicone is a condensed type of silicone with a shrinkage rate of less than 0.2%. The characteristics of condensed silicone depend on the degree of vulcanization and the additives used. Food grade silicone is an additive silicone with a shrinkage rate of less than 0.1%. Food grade silicone is a safe and healthy silicone mainly used in tableware applications. Its structure is stable and it is an inorganic polymer material formed by the condensation of silicic acid. Generally speaking, the shrinkage effect of silicone molds is very small, unless some large molds may have some impact, but with proper maintenance, shrinkage can be avoided.

matters needing attention
1. Silicone molds should be stored in a dry environment because silicone is a highly absorbent material.
2. When demolding, the mold should be completely cured before being removed, otherwise it will cause deformation and shrinkage of the silicone mold.
3. When using, it is important to follow the instructions and make the mold according to the manufacturer's instructions. The silicone mold is designed according to the manufacturer's specifications.
4. The larger the silicone mold, the easier it is to shrink, and caution should be taken when using it.
5. When using, gauze can be used to prevent mold deformation and shrinkage.
6. After using the silicone mold, it needs to be cleaned in a timely manner.

Some silicone molds have special usage environments, and it is normal for them to shrink after prolonged use. With the advancement of technology, many silicone molds now have good anti shrinkage properties. It is recommended that when choosing to purchase silicone molds, you choose to customize them from the manufacturer to ensure the quality assurance of bulk purchase of silicone molds.
