20 Kg bulk silica gel | white granular | drum

Loose white granular silica gel is a high-purity desiccant, packaged in a sealed 20 kg polyethylene drum. This premium-grade drying agent is widely used in industrial environments for large-scale moisture control and process applications, ensuring effective protection against humidity.

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 characteristics make it safe and versatile for a wide range of applications.

Structure: Characterized by a porous structure with a high specific surface area, which gives it superior moisture adsorption capacity.

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

Adsorption 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 ambient humidity:

* Note: The values indicated are obtained under laboratory conditions and represent average data. Actual performance may vary depending on usage configuration, airflow, grain size, and container used.

Main Application Fields

Loose silica gel is particularly suitable for medium to large-scale industrial applications such as:

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

Packing and Availability

This variant of granular silica gel is packaged in a sealed 20 kg polyethylene drum, ideal for industrial use and large-scale supply. The product is available for immediate delivery.

Other formats are also available – from 500 g to 25 and 30 kg drums – to meet different operational needs. Immediate availability and ease of ordering support efficient supply chains, even in dynamic production settings.

Safety and Compliance

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