Silica gel, known for its moisture-absorbing capabilities, excels in regulating humidity levels across diverse settings. This desiccant skillfully absorbs moisture and water vapour, reducing the risk of mould growth and spoilage in perishable goods.

Its moisture-absorption prowess extends its utility to safeguarding and preserving various items, such as food packaging and medication containers. Additionally, it serves as an effective mould deterrent in shoes and provides protection for electronic devices against potential damage.

Cost-Effective Moisture Solution

This desiccant is composed of silicon dioxide (SiO2), a naturally occurring compound found in quartz. Its molecular structure includes one silicon atom bonded to two oxygen atoms, forming a robust and stable lattice.

Once dried, this substance transforms into an effective moisture absorber for high-humidity environments. Silica gel particles possess microscopic pores that can absorb up to 40% of their weight and reduce relative humidity (RH) by up to 40% in a sealed container.

The pores attract water molecules, which adhere to the surface of each gel granule, effectively controlling moisture levels. Even when fully saturated, the desiccant granules remain dry due to capillary condensation. Saturated desiccant can be reused by heating it to 300ºF (150ºC) to expel the moisture.

Humidity Control and Mould Prevention

Our white, non-indicating gel is odourless, tasteless, non-corrosive, and chemically inert, making it safe for direct food packaging. It is non-toxic and solely absorbs moisture from enclosed spaces. A humidity indicator card can monitor the desiccant’s effectiveness and replacement timing.

For an indicating desiccant, we offer blue-indicating silica gel with cobalt chloride, which changes colour (usually to pink or red) upon saturation. This signals the need for replacement. This moisture absorber can be used for electronics or transformer breathers.

Additionally, our environmental gel, or orange-indicating desiccants, contains a safe organic indicator called methyl-violet. This desiccant changes from orange to green as it absorbs moisture, indicating full saturation and the need for replacement or reactivation. This desiccant is non-toxic, non-corrosive, free of heavy metals, and environmentally friendly.

Airtight Packaging for Optimal Protection

We also offer silica gel packets manufactured in our factory with ISO 9001 and 14001 certifications. These packets are available in a wide range of sizes, from 0.5 to 1000 grams, catering to diverse long-term storage requirements.

Our desiccants undergo regular inspections in our quality assurance laboratory to ensure the highest quality standards. Our desiccants are packed and delivered in an airtight protective container for optimal protection and effectiveness. We also offer bulk order options, customisation, and printing services for specific requirements.

Silica Gel is widely used as a desiccant in various applications like electronics, shoes, and food items to prevent moisture damage.

Handling Silica Gel: Silica Gel is generally safe to touch, but it is not recommended to ingest it or get it in your eyes. Prolonged skin contact may cause dryness or irritation, so it is advisable to wash hands thoroughly after handling. For safety, keep desiccants out of reach of children and pets.

Composition and Functionality: Silica Gel is a moisture-absorbing desiccant made from Silicon Dioxide, a natural compound found in rocks and minerals. It works by adsorbing moisture molecules through its tiny, porous particles, offering a large surface area for effective moisture absorption.

Mould Prevention: Silica Gel can help prevent mould growth by reducing moisture, which is required by moulds to thrive. While desiccant packets can mitigate moisture in prone areas, they might not completely prevent mould if other contributing factors, like leaks or poor ventilation, are present. Combining desiccants with other mould prevention strategies is recommended for better results.

Effectiveness When Wet: When Silica Gel becomes wet, its efficiency as a moisture absorber diminishes. The saturated particles cannot adsorb additional moisture, so it is important to keep the gel dry before use and replace it once saturated.

Lifespan: The longevity of Silica Gel varies based on factors such as the amount of absorbed moisture, storage conditions, and gel quality. Properly stored in a cool, dry place, the gel can last up to two years. However, exposure to high humidity will reduce its effectiveness and lifespan.

Post-Handling Care: Though not toxic, it is wise to wash your hands after handling Silica Gel, especially if you have sensitive skin or allergies. Ingesting the gel can also cause gastrointestinal discomfort.
