Buy silica gel from a German wholesaler

Silica gel is used to protect against moisture damage, as it can lower relative humidity. It takes the form of transparent beads comprised of silicon dioxide. The many small pores in the beads give silica gel a large internal surface area. This makes it suitable as a desiccant, as it adsorbs moisture in the form of water vapour from the ambient air. Buy silica gel from ThoMar OHG to obtain desiccants of perfect quality.

Buy silica for more dryness and security

Silica gel offers protection against moisture damage by lowering the relative humidity in a closed room (in-box desiccant) and thus the risk of condensation. Available loose / bulk and in packets, silica gel from ThoMar OHG is harmless and does not contain DMF. It is registered and approved according to REACH.

Silica gel bags – low-dust or dust-proof

Silica gel bags are considered THE classic desiccants. The small packaging units make silica gel the ideal companion for sensitive goods, as they can be added directly to product packaging. We offer silica gel packets in various designs with different types of wrapping material – low-dust or dust-proof. Low-dust and dust-proof enveloping bags differ in the density of their materials 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.

Silica gel as bulk material

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 is mainly used in industrial drying plants, in laboratories, in compressed air drying and in pressure compensation tanks. It is ideal for drying air and gases. Loose silica gel is filled in airtight packaging, in cans or bottles or as a packet or sack.

Silica gel orange – loose or in small packets

In addition to the properties of the classic whitish-colourless silica gel, loose silica gel orange has a special 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 useful aid.

Sizing: How much silica gel do I need to buy?

The question cannot be answered with a rule of thumb. Silica gel can absorb moisture. Depending on the type and quality of the product, the absorption capacity is between 25 and 39%. Very large-pored silica gel can in some cases absorb over 60% moisture. The exact quantity depends on the temperature and relative humidity within the protective airtight wrapping (airtight wrapping in which the goods are packaged). The goods in need of protection must also be taken into account when performing the calculation.

Regeneration: How often do I need to buy silica gel?

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