TROPAgel® Desiccant Bags and Sachets

Less Storage and Transport Damage = More Profit

TROPAgel® Desiccant bags, filled with highly active drying agents, offer the ideal solution for the protection of moisture-sensitive goods such as, Machine tools, Data processing plants, Optical and precision instruments, Electronic equipment, Pharmaceuticals, Chemicals, Military components, Leather goods and Food.

TROPAgel® Desiccant bags prohibit Corrosion

Corrosion protection is further required during the transportation of industrial steel and iron products, as well as for copper and aluminium goods which are usually transported in a hermetically sealed environment, where the formation of condensation water will have a corrosive effect on the transported goods. The formation of such condensation water may be triggered by a sharp fall in temperature.

TROPAgel® Desiccant bags with high capacity

TROPAgel® desiccant bags are manufactured with highly efficient drying agents allowing for a high adsorption and drying rate thanks to their superior porous properties. The adsorption capacity may be as high as 30% of its weight at 80% RH and 25°C. TROPAgel® desiccant bags are chemically inert and nontoxic for metal or any other materials.

TROPAgel® Desiccant Bags and Sachets unit amounts

The filling of the desiccant bags is measured in units. One desiccant unit is equal to the amount of a drying agent capable of adsorbing a minimum of 3g at 20% relative humidity and 6g at 40% relative humidity of water vapour at an air temperature of 23°C (±2).

The DIN 55473 only allows for the description in desiccant units. The following table offers an overview of the approximate amount of desiccant in each bag.
