Silicone is a granular and porous hydrate of silica, belonging to the amorphous substance, with a transparent or milky white appearance. Silicone is made by washing and drying sodium silicate with acid, which has stable chemical properties and does not burn. Silicone is a highly active adsorbent material mainly used as a desiccant and adsorbent in column chromatography and thin layer chromatography. Generally speaking, it can be divided into two categories: organic silicone and inorganic silicone. Its service life is generally five to eight years.

The service life of silicone products varies with different processes. The following are several common silicone products and their service life:

Ordinary solid-state silicone buttons have a lifespan of around 300000 times;

Liquid silicone buttons have a lifespan of around 50000 times;

Ordinary solid silicone tube with a lifespan of over 1000 days;

Liquid silicone tube with a lifespan of over 1500 days;

Ordinary solid silicone miscellaneous parts with a lifespan of over 300 days;

Liquid silicone miscellaneous parts with a lifespan of over 500 days.

In short, the service life of silicone products may vary depending on the manufacturing process. Different products and processes may have different lifespans.

The service life of silicone products may vary depending on the usage scenario:

For example, the quality of food grade silicone and medical silicone raw materials can ensure a normal service life of over ten years, and the storage time is unlimited. For some silicone products that have been affected by irregular water, light, heat, humidity, oil, etc. for a long time, such as silicone rubber belts, silicone daily necessities, silicone accessories, etc., their service life will be affected to a certain extent, but under normal use, there will be no problems for ten years.
