DESICCANT SILICA GEL

What is Silica Gel – Basic properties

Desiccant Silica Gel is silicon dioxide in a translucent granular form. It has a high porosity allowing it to absorb excess moisture in confined spaces.

Depending on the conditions of relative humidity and temperature to which silica gel is exposed, is more or less able to absorb moisture. Thus, at high temperatures the absorption capacity decreases.

Silica Gel packets are desiccant bags widely used to protect products from damage by moisture, during transport and during storage thereof. With the introduction of desiccant silica gel within the packaging prevents possible degradation or deterioration of those likely to have changes in the presence of ambient moisture products.

Silica gel sachets are definitely an ideal place to ensure the quality of goods during shipping or stockpiles in warehouses, can guarantee the condition of the product upon arrival at destination or after their stay in stock product.

Silica gel is a non-toxic and non-corrosive drying agent. Desiccant Silica Gel is used for many applications in several sectors.

Use

Silica packets can be used in any application that needs an absorption of humidity, both in packaging and closed spaces. The common feature is that the areas in which the silica gel is used must be confined, as otherwise absorb ambient moisture with consequent saturation product.

The desiccant silica gel is currently used in the following industries:

• Food industry (can be in direct contact with food through a special fabric bag)
• Pharmaceutical industry
• Textile, leather, fur, etc.
• Technology sector
• Chemical industry
• Medical equipments
• Optical instruments (photographic material)
• Technical equipments
• Flower drying silica gel
• Horticulture (dried plants, flowers and seeds)
• Pets

Desiccant silica gel is widely used for export, transport or storage of food or pharmaceutical products, as there is the possibility of placing the Silica Gel in direct contact with food or active ingredients using bags that meet the requirements of FDA (with bags Tyvek) type.

Specifications

Absorption capacity silica gel: 23 ± 2% of its own weight at an ambient temperature of 23 ° C and relative humidity of 40%.

Desiccant material: amorphous silica dioxide. Silica gel can be used with a substance that changes color, can recognize when the bag can no longer absorb moisture and, therefore, must be replaced (orange = active / green = exhausted).

Principal chemical and physical characteristics of desiccant silica gel:

4.- BULK: Another way to supply silica gel, both white and silica gel orange. The white product indicates no moisture absorption, whereas the orange product changes color when saturated with moisture. Silica gel comes in boxes of 25 kg of the product, with the following granulometry:

• Bulk Orange 2-5 mm: Change from orange (active) to green (saturated)
• Orange bulk 1.5 to 2 mm: Change color orange (active) to transparent (saturated)
• Bulk White 2-4 mm: No color change
