Flame Retardant Silicone Foam Sheet (Fire-Resistant Silicone Sponge)
UL 94 V-0 Silicone Foam Sheets Supplier
Flame retardant silicone foam sheets are engineered cellular elastomers designed to provide both thermal insulation and fire resistance for demanding environments.
These materials combine the high temperature tolerance of silicone with enhanced flame retardant properties that comply with common safety standards, making them suitable for electrical cabinets, appliances, transportation, battery, rail interiors, aerospace components and industrial enclosures where fire performance is critical.
Flame retardant silicone foam sheets can be designed to meet multiple fire and safety standards depending on application:
- UL 94 V-0 / VTM-0 – Vertical burn and flame tests for plastics and foams
- FMVSS 302 – U.S. automotive interior flammability
- EN 45545-2 – Railway fire safety standard
- NFPA 130 / NFPA 701 – Transit and textile flammability
- ASTM E84 (Class A/B) – Surface burning characteristics
- IEC 60695 – Fire hazard testing for electrical components
UL94 V-0 Approved Flame Resistant Silicone Sponge Sheet
Flame retardant silicone foam is a specially formulated variant of silicone sponge that incorporates fire-resistant chemistry and additives. Unlike standard silicone foam, which primarily focuses on thermal resistance and compression sealing, flame retardant silicone foam is optimized to resist ignition, self-extinguish once the source is removed, and minimize flame spread and smoke generation.
This makes it the preferred solution for installations where regulatory fire performance is required.

Quotations typically require:
- Target flame standard (UL 94 / EN 45545 / FMVSS 302 etc.)
- Thickness and density
- Format (sheet, roll, strip, kiss-cut, gasket)
- Dimensions or drawings (DXF/DWG/PDF acceptable)
- Required adhesive backing (if any)
- Estimated annual volume / order quantities
- Delivery terms and destination country
- Providing regulatory standards up front significantly reduces back-and-forth in quotation.
Flame retardant silicone foam should be specified when the installation is subject to regulatory fire performance requirements such as UL 94, EN 45545-2, FMVSS 302 or building fire codes. This applies to electrical cabinets, rolling stock interiors, appliance housings and battery modules where ignition resistance and self-extinguishing behavior are safety-critical. Standard silicone foam is suitable for non-regulated insulation and general enclosure sealing.
Yes. Flame retardant silicone foam offers both insulation and compression sealing. The cellular structure provides thermal isolation, while controlled compression force deflection enables environmental sealing against dust, air and moisture when the gasket is clamped between panels or doors.
Not directly. Flame retardant silicone foam improves ignition resistance and self-extinguishing behavior but does not expand to form a char barrier like intumescent materials. For fire containment or structural fire barriers, intumescent or ceramic fiber materials may be required.
Yes. Silicone foam gaskets can be provided with pressure-sensitive adhesive on one or both sides and kiss-cut on liners to support automated or manual assembly. Adhesive type should be selected according to substrate material and service temperature.
Yes. Silicone provides excellent UV, ozone and weathering resistance, making it suitable for outdoor cabinets and infrastructure installations. This differentiates it from polyurethane foams, which degrade quickly under UV exposure.
