Silicone desiccant is a moisture-absorbing dehumidifier that removes moisture from the air. The drying principle is to physically absorb water molecules into its structure or to chemically absorb water molecules and change their chemical structure into another substance.

The main component is silica gel, with a chemical formula of mSiO2.nH2O, which is made from natural minerals through purification and processing into granular or bead-like forms. As a desiccant, its microporous structure (average pore size of 2A) has a good affinity for water molecules. Silica gel is most suitable for humid environments at room temperature (20~32°C) and high humidity (60~90%), which can reduce the relative humidity of the environment to about 40%.

The appearance is transparent or semi-transparent solid granular, colorless, odorless, non-toxic; it absorbs moisture through physical adsorption, with mild performance and no violent changes, making it reliable and safe. The humidity of the desiccant itself is below 8%, and under the correct dosage and 100% atmospheric humidity, the desiccant can control the atmospheric humidity to 40%. It is widely used in the prevention of moisture in products such as crafts, clothing, footwear, luggage, leather, medicines, food, instruments and instruments.
