Testing & Proof
Proven where it matters — under fire
Materials for battery safety only count if they hold up in a real thermal runaway. Here is the third-party and in-house evidence: UL2596 enclosure tests, nail penetration, direct-flame and potting demonstrations.
The moment it matters
Direct flame, contained
A closer look at peak flame during the UL2596 enclosure test — the protected pack holds while heat and pressure build.
UL2596 — EV battery enclosure
Pyrowerkz contains a battery fire
Third-party UL2596 EV Battery Enclosure Material Safety Test (Project No. 4791261656). Without protection, the plastic lid blows off and fire spreads. With a Pyrowerkz-adhered lid, the pack contains the fire and holds structural integrity under impact and pressure.
What we test for
UL2596
Battery enclosure fire safety
Third-party EV battery enclosure material safety testing — fire containment and structural integrity through a thermal-runaway event.
Nail penetration
Induced cell failure
Deliberate cell puncture to trigger and observe thermal-runaway propagation — and how our materials arrest it.
Direct flame
Up to 1200-1500 °C
Direct-flame exposure of coated substrates and sheets, measuring backside temperature and burn-through resistance.
Potting
Cell-to-cell propagation
A normal pack sees multiple explosions from propagation; a Thermorphous-potted pack protects all but the punctured cell.
Direct-flame demonstration
A coated sheet under a direct torch
A Matwerkz protective sheet held under direct flame — the material chars and insulates rather than igniting or burning through.
SF203 coating: 1200 °C, backside stayed at 126 °C
In flame testing, a plastic (PP) substrate coated with SF203 withstood direct flame at 1200 °C for over 10 minutes — preventing ignition, burn-through and structural failure. After 3 minutes of fire exposure, the backside temperature of the coated sample remained as low as 126 °C, whereas an uncoated sample would have burned through.
