Blue silicone is a type of silicone that is used to absorb moisture and has a discoloration characteristic. It has blue or light blue glassy particles on the outside.

Main features

Color discoloration characteristics: After the blue silicone absorbs moisture, the color will change from blue to pink. This characteristic allows it to intuitively indicate the relative humidity of the environment and the degree of moisture absorption of the desiccant.

Hygroscopic properties: Blue silicone has strong moisture absorption ability, can absorb moisture in the air and keep the environment dry.

Widely used: Blue silicone is widely used in the packaging of precision instruments, leather, clothing, food, medicine and household appliances for moisture resistance.

Specifications and packaging

Specifications: The particle size of blue silicone has a variety of specifications, such as 1~3mm, 2~4mm, 2~5mm, 4~8mm, etc., which can be customized according to user needs.

Packaging: Blue silicone has a variety of packaging forms, including 25KG composite bags, 25KG cardboard buckets, 12.5KG and 25KG iron barrels, 800KG and 500KG container bags, etc.

Use and precautions

Use: Blue silicone can be used alone or in combination with ordinary silicone desiccant to indicate the moisture absorption of the desiccant.

Note: Blue silicone contains a small amount of cobalt chloride, which is toxic and should be avoided from contact with food and inhaling it into the mouth. If a poisoning occurs, seek medical treatment immediately.

Regeneration and processing

Regeneration: After the blue silicone is saturated, its moisture absorption capacity can be restored through regeneration treatment. The regeneration method includes thermal desorption, calcination method, etc.

Treatment: Used blue silicone should be treated in accordance with relevant regulations to avoid pollution to the environment.
