You can order your silica gel products directly from our B2B Shop or contact us to request for a quote.

Should you choose low-dust or dust-proof silica gel bags?

Silica gel bags are considered a classic desiccant. These compact units mean silica gel is ideal for use with sensitive goods as they can be placed directly against product packaging. We offer silica gel packets in various designs with a choice of low-dust or dust-proof wrapping material. Low-dust and dust-proof enveloping bags differ in their density and the amount of dust that can penetrate through them.

Silica gel packets with low-dust or dust-proof wrapping material can also be manufactured to customer specifications.

Using silica gel desiccant in bulk

When processing, storing and transporting products, loose silica gel can be used in a variety of ways to protect against moisture and wetness damage such as corrosion and mould. It’s mainly used in industrial drying plants, laboratories, compressed air drying, and in pressure compensation tanks. It’s ideal for drying air and gases. Loose silica gel comes in airtight packaging, in cans or bottles, or as a packet or sack.

Buying silica gel orange – order loose or in small packets

In addition to the properties of the classic whitish-colourless silica gel, loose silica gel orange has an extra feature. It has a practical indicator that changes colour from orange to green at a saturation of approx. 6%. The more water it absorbs, the more intense the green colour becomes. When silica gel becomes a green-blue colour, the maximum saturation of the desiccant has been reached. The indicator is an uncomplicated and invaluable aid.

How much silica gel desiccant do I need?

This question requires a precise answer. Depending on the type and quality of the silica gel product, it will have an absorption capacity of 25%–39%. Very large-pored silica gel can in some cases absorb over 60% moisture. The exact quantity of silica gel you need will depend on the temperature and relative humidity within the protective airtight wrapping (i.e.,the airtight wrapping in which the goods are packaged). The goods in need of protection must also be taken into account when calculating the amount.

What is recharging silica gel?

Unbagged and bagged silica gel releases absorbed water vapour again at very low humidity, which can be used for regeneration. However, industrial desiccants are normally not intended for recharging silica gel. The cost of the energy required for recharging silica gel usually exceeds the cost of replacement. Loose silica gel is an exception in this respect. It's mainly used in laboratories and can be regenerated at approx. 130°C.
