How to solve the problem of yellowing of silicone products?

Nowadays, silicone products can be seen everywhere in the market. Especially in the fields of daily life, medical food, industrial equipment, digital electronics, etc., our common silicone products include silicone hoses, silicone phone cases, silicone kitchen supplies, etc.

However, after long-term use, we will find that silicone products gradually turn yellow, especially for transparent silicone products.

During the production of silicone products, controlling yellowing issues can be approached from the following three points:

1. Using high-quality silicone raw materials

2. Add sulfurizing agents with anti yellowing properties

3. Control the temperature and vulcanization time of silicone product molds in terms of process

There are several ways to control yellowing of silicone products in daily life:

1. Cleaning with toothpaste: Apply toothpaste evenly onto the yellowed silicone product, wait for a moment, then gently brush with a soft bristled brush, and finally rinse with clean water. Can the friction agent and cleaning ingredients in toothpaste effectively remove yellow stains?

2. Use bleach powder: Dilute the bleach powder according to the instructions, soak the silicone product for a period of time, and the yellow stains will be removed by the strong oxidizing properties of the bleach powder. Pay attention to wearing gloves and masks to ensure safety?

3. Using lemon juice: Add lemon juice to clean water and soak the silicone product for 10-15 minutes. The fruit acid in the lemon juice helps dissolve yellow stains. Then gently brush with a soft bristled brush, and finally rinse with clean water?

4. Using rice washing water: Soak the silicone product in the rice washing water for 10-15 minutes. The alkaline component of the rice washing water can neutralize the acidic substances on the surface of the silicone. After soaking, gently brush with a soft bristled brush and finally rinse with clean water?

5. Use essential oil: Apply essential oil onto yellowed silicone gel, wipe repeatedly with a glasses cloth, and then rinse with clean water. Can the ingredients in Fengyoujing effectively remove yellow stains?

6. Using disinfectant (such as 84 disinfectant): Soak silicone products in water mixed with 84 disinfectant for 10 minutes. The bleaching effect of the disinfectant can turn yellowed silicone white. But should we pay attention to safety measures when using it?

7. Use an eraser to wipe: For silicone products with less severe dirt, you can use an eraser to wipe the surface dirt to achieve a cleaning effect

Overall, the yellowing phenomenon of transparent silicone products can only be alleviated, but cannot be completely avoided. Generally speaking, yellowing of silicone products does not affect normal use, and it is recommended that you do not need to replace them frequently.
