Protect-o-Burn International is the leading developer of Self-Expanding Hydrogel, a superior fire extinguishing system for battery fires, which effectively eliminates radiant heat transfer and oxygen, providing rapid cooling and exceptional protection through encapsulation
Protect-o-Burn International established itself more than 20 years ago in the market with Self-Expanding Fire Fighting Foam and has in excess of $115bn in assets under its technology protection, utilising third-party pre-engineered designs, maintaining international code compliance and AHJ involvement throughout the process.
Protect-o-Burn International is at the forefront as the global leader in the development of Self-Expanding Hydrogel, suited for all related Battery Fires, offering superior protection pre- and post-ignition. Hydrogel is listed under EN 3-7, supplied and developed in conjunction with Anogas BV.
The benefits of Self-Expanding Hydrogel
The critical amount of radiant heat transfer, in combination with the Thermal runaway that has taken place, is totally eliminated with the unique barrier that Self-Expanding Hydrogel provides, with the micro clay platelets super expanding rapidly, secluding all oxygen, covering the entire area and rapidly cooling down – far superior to water and additives!
Our Patented Self-Expanding Technology ensures a totally inert environment, not only secluding oxygen but also having a rapid cooling effect, as opposed to a bubble having an oxygenated state.

We enhance the cell structure in the area of joining and, through a chemical push-pull principle, create excellent reach with just internal pressure. There is no need for external pressure sources or mixing on site in the event of a fire. From handheld units to large, fixed installations, there is no area too small or too big that cannot be protected.
SEH is an innovative fire extinguishing agent with a minimum expansion ratio of 1:10 based on a revolutionary patented technology.

Protect-o-Burn offers a single unit that can protect various BESS units from a single location. A 12,000-litre complete autonomous unit provides up to an immediate 120,000 litres of Self Expanding Hydrogel!
With this unique, new approach, no Fluorine chemistry is necessary and there is no compromise made in fire extinguishing effectiveness, environmental friendliness and human safety.
The main ingredients of SEH are very small mineral clay platelets, with a huge surface area of more than 500 m² per gram. The clay platelets are modified with a thermal responsive additive and dispersed in water. The water content of SEH is more than 95% and more than 99% of its content is nature based.


The only Aviation Flight Safety Bag that totally encapsulates a PED and maintains the Self-Expanding Hydrogel integrity for up to 24 hours, not only meeting the UL5800 test protocol and FAA minimum criteria, but exceeding it by far!
We offer a wide range of CE / TUV SUD handheld and wheeled extinguishers with MED Marine certification.
