TROPAgel® highly activated desiccant bags

TROPAgel® bags are made using highly activated desiccants. Be it clay, silica gel or molecular sieves combined with non-woven , Tyvek® or paper, our wide range of products can flexibly cater to your specific requirements, offering you just what you need.

TROPAgel® desiccant bags are chemically neutral, and not corrosive to metals or other materials. To ensure optimum function, it is important to use sufficient desiccant, and determine the exact amount required using a proper calculation method complying with DIN 55474.

TROPAgel® desiccants

Standard TROPAgel® desiccant bags contain clay/bentonite or silica/white gel. The bags’ adsorption capacity complies with DIN 55473 requirements. Our wide range of desiccants for these bags includes:

  • Clay: A natural, safe all-rounder, suitable for standard applications in all areas of industry
  • Silica gel: Commonly found in small packaging used in industry, pharmaceutics, diagnostics and the food sector due to its high adsorption capacity
  • Orange gel: Silica gel with a colour indicator from orange to white – safer and more efficient due to the ability to check saturation visually
  • Rubingel: Silica gel with a colour indicator from ruby/red to yellow – safer and more efficient due to the ability to check saturation visually
  • Molecular sieve: Suitable for pharmaceutics and diagnostics, as well as special technical applications (various types: 3Å, 4Å, 5Å, 10Å / 13X)

The benefits of TROPAgel® desiccant bags

  • Efficient and reliable regardless of requirements
  • Flexible dimensions to suit any purpose
  • Environmentally friendly – may be disposed of as household waste

The highly adsorbent TROPAgel® desiccant bags provide reliable protection against moisture and corrosion. Top DIN 55473-certified quality.

TROPAgel® desiccant bags are suitable for all kinds of applications, including machine tools, controls, visual measuring instruments, electronic devices, chemical and pharmaceutical products, diagnostics and food.

Desiccant bag materials

Standard TROPAgel® desiccant bags bear DIN-Certco seals 5B003 and 5B004, are designed in accordance with DIN 55473 (12/2015 edition), and are dust-proof.

All desiccant bags can also come with a 40% indicator, enabling you to monitor the relative ambient humidity.
Bag material types:

  • VA – Dust-proof bag made from highly tear-proof fleece / suitable for all packaging purposes
    |1/6 - 32 units / with hanging straps when units are 16+.
  • TA – Dust-proof Tyvek bag made from a special highly tear-proof and low-particulate material / for the pharmaceutical industry, electronics, and heavily used packaging / complies with FDA requirements (21 CFR 177.1520) [e.g. Mini desiccant bags]. 
    |1/6 - 16 units
  • PA – Dust-proof desiccant bag made from kraft paper / resistant to mechanical loads
    |1/6 - 2 units
  • VA  / ESD – Desiccant bag made from highly tear-proof non-woven, with additional anti-static coating  (ESD-certificate
    |1/6 - 32 Units

Custom designs and product development

We’ll be glad to design customised desiccant bags tailored to your requirements.

Our desiccant bags are available in special sizes and different forms, including chains. As an additional service, we can print custom lettering or designs (e.g. company logos) onto the bags according to your specifications.

 
 

Desiccant quantities

The standard desiccant bags are filled by units in accordance with DIN 55473. One desiccant unit is equal to the amount of desiccant which – at equilibrium with air – can adsorb at least 6 g of water vapour at 23°C (±2°C) and 40% relative humidity.
DIN 55473 stipulates that only desiccant units be used as the unit of measurement. See the table below for the approximate fill quantities – based on clay.

Basic Packets

TROPAgel® desiccant bags come in basic packets with the usage instructions printed on them.
These packets consist of DIN 55473-compliant poly bags, and are suitable for all bag types.

Shelf life

TROPAgel® desiccant bags may be stored in a dry place at room temperature for extended periods of time without losing any of their effectiveness. Every packet contains a moisture indicator for visual checks set at 8% relative humidity .
Shelf life in sealed packaging:
    Standard (in a cardboard box) – 6 - 9 months
In a metal bucket (optional)  – up to 24 months

Shipping

The packaging used for shipment consists of a corrugated cardboard with a net weight of approx. 20 kg. A full pallet holds 27 cardboard boxes. The standard packaging contains the following quantities of our desiccant bags:
