Built-In Fire Protection Inside Materials

Heat-activated microcapsules that suppress fire at the source inside coatings, polymers, and OEM systems.

No wiring, no sensors, no power
Activates automatically at high temperature
No residue, safe for electronics

The Problem

Fires start inside materials and components
No protection at material level
Traditional systems react too late
Hidden ignition sources (wires, batteries, coatings)

How It Works

Each microcapsule contains FK-5-1-12 clean agent.When temperature rises, capsules rupture and release the agent directly at the ignition point, suppressing fire instantly.

Inside the Technology

See how microcapsules are formed and how the clean agent is encapsulated inside a polymer shell.
