Ceramifiable / Fire Barrier Silicone Foam
A silicone foam that behaves as a normal compressible gasket under standard service conditions, but undergoes ceramification when exposed to fire, forming a rigid inorganic barrier that maintains the seal and blocks flame propagation through the penetration.
Strengths
- Converts to ceramic upon fire exposure — structural seal survives post-fire
- Maintains closure of cable and duct penetrations after the fire event
- Handled and compressed like a normal foam — no special installation tooling
- Qualified to fire-resistance test standards (UL, IEC, EN — grade dependent)
- Die-cut conversion to custom cable-tray, duct, or panel shapes
- Suitable for passive fire protection (PFP) system integration
Customization
- Custom compound matched to a specific fire test standard rating
- Density grade and thickness selection per closure force requirement
- Adhesive backing for fixed-installation products
- Coextruded profiles for pipe sleeve and annular penetration seals

Installation Notes
- Cable tray and conduit penetration fire stops
- EV battery module inter-cell fire-barrier layer
- Marine and offshore structural bulkhead seals
- Railway vehicle compartment fire partitions
- Building construction passive fire protection
- Industrial switchgear and control panel fire strips
Installation Notes
- Install compressed at 20–30% deflection — do not over-compress
- Wear standard PPE during cutting and handling
- Post-fire residue is inert ceramic mineral — dispose as inert waste
- Engage relevant fire certification body before use in life-safety applications
Frequently asked questions
What is the most distinctive function of Ceramifiable / Fire Barrier Silicone Foam?
Its most distinctive function is high-temperature ceramic conversion, allowing the foam to form a rigid ceramic-like protective layer that blocks flames and slows heat transfer.
Is this material only for fire barrier use?
No. At room temperature it also provides sealing, damping, and thermal insulation before any fire event occurs.
What makes it relevant for battery and ESS systems?
The TDS explicitly states it is used in energy storage units and between power battery cells to delay thermal runaway propagation.
Can it be converted into custom parts?
Yes. The TDS lists both customized sheet products and customized die-cut products.
What flame rating is listed?
The TDS lists UL94 V0 flame retardancy.
