Advanced fire-suppression materials

Heat-activated microcapsule technology for fire suppression.

FireXNull develops heat-activated fire suppression microcapsules for compatible coatings, materials and electrical enclosures. Our passive technology releases a clean suppression agent at a preset activation temperature—without external power, sensors or manual activation.

01 / Material integration

FXN-M200 Microcapsule Additive

A heat-activated fire suppression additive for formulators developing compatible coatings, polymers and composites.

Coating Systems

For integration into compatible protective coating formulations.

Adhesives

For evaluation in compatible adhesive formulations.

Sealants

For evaluation in compatible sealing compounds.

Composites

For integration into compatible composite material systems.

Compatibility and fire suppression performance depend on the final formulation and must be validated by the formulator.

02 / Ready-to-use products

For enclosed electrical systems and wire connections

The same heat-activated microcapsule technology, built into finished products for electrical enclosures and wire connections.
