How long can silicone desiccant prevent moisture

The validity period we usually set for use is within one year when the desiccant is not opened and sealed for use. If it is already in use, it should be calculated based on factors such as the environment, humidity, sealing, space size, and weight of use. Its moisture-proof time is directly proportional to these factors, and it depends on the moisture absorption rate. Generally, the moisture absorption rate of silicone is about 30%. After the moisture absorption is saturated, it becomes ineffective.

The use time of desiccants is not in the true sense of time, but rather in terms of moisture absorption rate. That is to say, as long as it absorbs 30% of its own weight of water, it basically has no effect, it doesn't depend on how long it has been used.

Silicone desiccants are insoluble in water and any solvents, and their raw materials have been certified by the US FDA. They can come into direct contact with drugs and food. Our company's products meet certification requirements such as ROHS, REACH, and DMF free. In addition to the above factors, silicone desiccants also have strong moisture absorption ability and strong adsorption performance, and will not melt after moisture absorption. It has the characteristics of being harmless, odorless, non corrosive, and non polluting, and even if ingested, it will not be absorbed by the human body. Widely used in: biological reagents, food, pharmaceuticals, electronics, health products, etc.
