The main reasons for the yellowing of silicone are as follows

The main reasons for the yellowing of silicone are as follows:

1: Oxidation reaction: Oxygen in the air slowly oxidizes with the silicone material, resulting in color change. 

2: Pollution and improper cleaning: accumulation of dirt and the use of detergents containing corrosive ingredients can also contribute to yellowing.

Storage environment: Humid or high temperature environment accelerates the aging of silica gel, which in turn yellows.

3: Sulfurizing agent: the use of ordinary type non-yellowing sulfurizing agent will lead to silicone products in the production of a few years or months after the yellowing phenomenon.

4: mold temperature and vulcanization time: mold temperature is too high or vulcanization time is too long will lead to silicone products in the molding of yellow color.

5: the quality of raw materials: the raw material itself is of poor quality, anti-yellowing ability is weak, will also lead to yellowing silicone products in the process of use.

In order to prevent silicone yellowing, you can take the following measures:

1: Choose high-quality silicone raw materials: use silicone raw materials with high transparency and good anti-yellowing properties. 

Control vulcanizing agent and process: Use anti-yellowing vulcanizing agent, and strictly control the mold temperature and vulcanization time.

Correct storage: Store silicone products in a cool and dry place, avoid direct sunlight. 

2: Regular cleaning: Use appropriate cleaning agents such as toothpaste, detergent or alcohol to clean the surface of the silicone, and avoid using cleaning agents containing corrosive ingredients. 

Through the above methods, you can effectively slow down the process of silicone yellowing and keep its beauty and durability.
