Rapid heat absorption
An endothermic response draws substantial energy away from the fire source and helps lower local temperature.

About Akusta
An active fire barrier created by the material itself
FlameEL® Akusta is a Steam-Releasing Flame-Retardant resin (SRFR resin) developed by KhaiEL. Unlike a material that only resists fire passively, it absorbs substantial heat at elevated temperatures, releases water vapor to cool the source, and forms a protective layer on the material.
The system is designed for self-extinguishing performance and the suppression of flame spread, with lower reliance on harmful emissions during fire protection. Its moldability also helps integrate fire protection into different shapes and component designs.
Product Features
Four core material attributes
From heat management to processability, Akusta integrates an active fire-suppression mechanism into a moldable resin system.
Steam suppression
Aluminum hydroxide decomposes under heat and releases water vapor to cool and suppress the fire.
Protective barrier
Decomposition creates an alumina layer that isolates the source and limits further flame spread.
Moldable design
The resin can support component geometry and molding needs so fire protection can become part of the structure.
Fire Suppression Mechanism
A three-stage active response
High temperature triggers a continuous reaction—from heat absorption to steam release and finally the creation of a solid barrier.
Rapid heat absorption
The material first absorbs a significant amount of energy from the fire source, lowering the surrounding temperature.
Endothermic steam release
As temperature rises, aluminum hydroxide decomposes endothermically and releases steam to cool and suppress combustion.
Alumina isolation layer
The resulting alumina forms a protective barrier that isolates the source and helps preserve the base material.
Technical Snapshot
Key figures reported in the article
These values are taken from the Archify feature. Final material and component design should be evaluated against technical documents and project-specific testing.
Composition
High aluminum-hydroxide content
The core component is Al(OH)₃, whose endothermic decomposition drives the active fire-suppression response.
