Birchsorb hyperdesiccant™

Combat Container Rain with Moisture Control for Shipping Containers

Insurers estimate that 10% of goods shipped worldwide are damaged beyond repair by humidity and temperature changes creating what is known as “container rain”, causing mould, corrosion, peeling and destroyed or damaged packaging.

Birchsorb is long lasting and hyper efficient.

While traditional moisture control solutions do not last over the course of long shipping routes, leaving goods vulnerable to damage, BirchSorb hyperdesiccant™ is designed to last for up to 12 weeks.

Birchsorb outperforms its competitors.

BirchSorb™ is a unique moisture control solution for shipping containers - it absorbs three times its own weight in moisture quickly and efficiently, with no chance of moisture re-release even in hot environments. It’s more effective than Silica Gel, Desiccated Clay or Calcium Chloride while remaining cost-efficient to use - and thanks to our global network, it’s available worldwide.

We produce, refine, test and innovate all of our solutions on-site giving us optimum performance, industry-leading supply and delivery times, and unrivalled quality for every product in the Birch Chemicals line.
