25 Kg bulk silica gel | white granular | drum

Bulk white granular silica gel is a high-purity desiccant packaged in a sealed 25 kg polyethylene drum. This high-quality dehydrating agent is widely used in industrial settings for humidity control on a production scale and in process applications, ensuring effective moisture protection.

It is available in three main grain sizes to suit different technical requirements:

6 - 8 mm (default): larger grains, suitable for large volumes and systems with air circulation. They promote lower pressure drop and better flow distribution, making them ideal for large-scale filters and dynamic applications.

2 - 5 mm: intermediate and versatile grain size, suitable for most applications. It represents a balance between available surface area and airflow permeability.

0.5 – 2 mm: finer grains, suitable for limited spaces, compact cartridges, or small filters where it is necessary to maximize the amount of material in limited volumes. They require caution in airflow applications due to the higher compactness of the bed.

Product Features

Composition: Purified silicon dioxide processed into high-quality granules.

Properties: Odorless, tasteless, non-toxic, non-corrosive, and chemically inert. These features make it safe and versatile for a wide variety of applications.

Structure: Characterized by a porous structure with a high specific surface area, providing excellent moisture adsorption capacity.

Stability: Non-deliquescent, meaning it retains a dry surface even when fully saturated, without releasing moisture into the environment.

Absorption Capacity

Silica gel removes moisture up to 65 °C but performs best at room temperature (20–30 °C) and under high relative humidity (60–90% RH).

Below are indicative values of its adsorption capacity depending on environmental humidity:

* Note: The values shown are based on laboratory conditions and represent average data. Actual performance may vary depending on usage configuration, airflow, particle size, and container used.

Main Application Areas

Bulk silica gel is particularly suitable for medium and large-scale industrial applications, such as:

• Industrial Production: Used for humidity control in manufacturing processes and for protecting raw materials and finished products in large volumes.
• Drying Systems: Used in industrial air dehumidification systems to prevent corrosion and material degradation.
• Laboratories and Chemical Sector: For drying reagents, gases, and moisture-sensitive materials in controlled environments.

Packaging and Availability

This version of granular silica gel is packaged in a sealed 25 kg polyethylene drum, ideal for industrial use and bulk supply. The product is available for immediate delivery.

Other formats are also available – from 500 g to 20 and 30 kg drums – to meet different operational needs. Fast availability and easy ordering help ensure efficiency even in dynamic production environments.

Safety and Compliance

Silica gel complies with safety and non-toxicity standards. It is free from DMF (dimethyl fumarate) and meets CE regulations.
