1. Prolonged growth
Silicone products will age when exposed to air for extended periods of time, especially in hot, humid or high-pressure environments. This aging will cause the silicone surface to decompose, forming a sticky layer that increases the elasticity of the silicone surface.
2. Plasticizer migration
In some cases, silicone may contain additives, such as plasticizers, to make the product brittle or brittle. Over time, however, plastic ingredients can leach from the material to the surface, causing the surface to become sticky. This usually happens with poor quality or poor quality silicone products.
3. The environment
The surface of the silicone can change due to dirt, dust, grease and other materials sticking to the environment. When these materials come into contact with the silicone surface, they will reduce absorption and create a more pronounced sticky feel.
4. Improper cleaning and maintenance
During use, if silicone products are not properly cleaned and maintained, dirt or grease can accumulate on the surface, slowly causing the silicone to stick. Therefore, keeping silicone products clean and dry is an effective way to prevent them from becoming sticky.
5. Chemical reactions
Although silica gel has excellent chemical stability, some chemicals (such as strong acids, strong bases or certain solvents) can cause silica gel to become chemically reactive and change its surface structure , to keep it sharp.
If your silicone products are sticky, here are some solutions:
Cleaning: Clean silicone surfaces with warm water and mild detergent to remove surface contaminants.
Powder: Rub a few drops of talcum powder or baby powder on the silicone surface to make it sticky.
Replacement: If the silicone is significantly aged or the plasticizer migration is irreversible, it is recommended to replace it with a new silicone material.
Silicone can become sticky for a variety of reasons, including corrosion, plasticizer migration, environmental damage and improper maintenance. With proper care and maintenance, the life of silicone products can be extended and their physical properties maintained.
