silicone masks work well. At present, many domestic companies and masks are using silicone.

1. Silicone is non-toxic and tasteless, some rubbers are toxic and delicious.

2. Silicone is soft and comfortable. The comfort of rubber is obviously not as good as that of silicone. Silicone is easier to bind to the face and has a tight seal.

3. The chemical stability of silica gel is very strong, and it is not easy to react with other chemicals. In particular, it does not react to oils, paints, acids and alkalis. Rubber deforms quickly in oil.

4. Silicone is easy to clean.

5. The service life of silica gel is very long. Even if the seal ring of silica gel is generally under the environment of high temperature, high pressure, water and oil, there is no problem within 5 years, and the aging resistance of rubber is obviously poor.
