Silicone molds are made of silicone as raw materials, and no matter what type of silicone mold you have, there will be a slight degree of shrinkage. The degree of exponential contraction varies, and the contraction does not affect less precise products because the degree of contraction is small.

Silicone molds include molds made of industrial-grade silicone and molds made of food-grade silicone. The degree of shrinkage varies according to its type. Industrial grade silicone is a condensed silicone with a shrinkage rate of less than 0.2%. The properties of condensed silicones depend on the degree of vulcanization and the additives used. Food grade silica gel is an additive silica gel with a shrinkage rate of less than 0.1%. Food grade silicone is a safe and healthy silicone that is mainly used in tableware applications. Its structure is stable, and it is an inorganic polymer material formed by condensation of silicic acid. Generally speaking, the shrinkage effect of silicone molds is minimal, unless some large molds may have some effects, but shrinkage can be avoided with proper maintenance.

Precautions
1. Silicone molds should be stored in a dry environment, because silicone is a material with strong water absorption.
2. When demolding, it should be taken out after the mold is completely cured, otherwise it will cause deformation and shrinkage of the silicone mold.
3. Be sure to follow the instructions for use when using, and make the mold according to the manufacturer's instructions. Silicone molds are designed according to the manufacturer's specifications.
4. The larger the silicone mold, the easier it is to shrink, so you should be cautious when using it.
5. Gauze can be used to prevent mold deformation and shrinkage.
6. The silicone mold needs to be cleaned in time after use.

Some silicone molds have a special use environment, and it is normal for them to shrink after long-term use. With the advancement of technology, many silicone molds now have good shrinkage resistance. It is recommended that when you choose to purchase silicone molds, you should choose factory customization to ensure the quality assurance of bulk purchase of silicone molds.
