Heat-activated microcapsule technology for fire suppression.
FireXNull develops passive, heat-activated microcapsules that release a clean suppressant the moment heat is detected — no power, no sensors, no manual activation.
Heat is the trigger. Nothing else is needed.
FireXNull develops heat-activated microcapsule technology: passive protection that releases a clean suppressant agent the moment it detects heat.
No external power, wiring, sensors, batteries, pressure cylinders, or manual activation — just heat.
FXN-M200 Advanced Microcapsule Additive
Engineered for integration into compatible coatings and material systems — localized fire-suppression functionality built directly into your materials.
FXN Microcapsules integrated into a compatible coating system and tested under direct flame exposure, releasing clean agent at the point of ignition.
Available for evaluation. Compatibility and performance depend on your formulation and processing method.
Available for evaluation as a component-level additive in compatible material systems.
For enclosed electrical systems and wire connections
The same heat-activated microcapsule technology, built into finished products for electrical enclosures and wire connections.
