10g Silica Gel Desiccant

Description

What is 10g Silica Gel Desiccant and How Does It Work?

10g Silica Gel Desiccant is a glass-like, porous form of silicon dioxide (SiO₂). It can adsorb up to 30% of its own weight in moisture. And yes — that’s adsorb, not absorb. Silica Gel adsorbs moisture as water molecules adhere to the surface of each bead. Each granule contains millions of microscopic pores, with pore openings measured on a nanometre scale. These pores create a huge internal surface area that binds water through surface adsorption and capillary action.

Silica Gel packets provide an economical and effective method of protecting items from moisture damage during transit and storage. Our sachets are filled with non-indicating beaded silica gel desiccant and are available in a variety of sizes.

Silica Gel is ideal for protecting electronic equipment, cameras, tools, computers, musical instruments, preservation packaging, and all humidity-sensitive products.

Our silica gel sachets are packaged in Aihua material. Despite the name, Aihua “paper” is not paper — it is a polymer made from Polypropylene (PP) and Polyethylene (PE). It is lightweight, flexible, tear-resistant, semi-transparent, smooth, and contains no harmful substances.

The Pro-Ex silica gel range is food grade.

Suitability

Silica Gel desiccants are available in different grades, each offering slightly different adsorption characteristics. A particular type of silica gel will typically reach its maximum adsorption capacity at a specific relative humidity, with performance decreasing above or below that point.

Under optimal conditions, silica gel may adsorb up to 30% of its own weight, but in practical use it is usually lower. Its adsorption ability decreases at temperatures above 30–40°C. While some moisture can still be adsorbed at temperatures up to 80°C, the risk of re-evaporation of previously adsorbed moisture makes silica gel unsuitable for environments where temperatures above 40°C may occur, even temporarily.

Note: Silica Gel desiccants are not suitable as shipping desiccants, but are ideal for smaller packaging applications where the risk of high temperatures is low.
