The latest self-working fire extinguishing agent, which allows to neutralize local ignition at its initial stage. This is an unparalleled autonomous fire extinguishing device, which appeared as a result of the use of domestic developments in the field of nanotechnology. The pyrosticer is a thin flat plate with millions of microcapsules containing a thermally activated extinguishing agent (flame retardant). When the temperature rises to 100-120 ° C, the microcapsules instantly burst, after which the flame retardant begins to actively affect the source of ignition. Pyrosticers are called an intelligent fire extinguishing system, since everything happens automatically when the external temperature changes. By releasing the gas from the microcapsules, this remedy continues to act until the ignition source is completely suppressed.
