Silicone Foam Rubber SM150-FG1
SM150-FG1 is an ultra-thin two-layer composite material uniformly coated with solid ceramifiable silicone rubber on one side. At room temperature, it retains the elasticity, sealing capability, and processability of silicone rubber. Under high-temperature flames or extreme overheating above 500°C, special additives react with the silicone matrix and sinter into a hard, porous ceramic-like crust, helping provide fire resistance, flame retardancy, ablation resistance, and an insulating thermal barrier.
Principaux avantages
- Ultra-thin two-layer composite structure for space-constrained fire-barrier and sealing applications
- High-temperature ceramic conversion that forms a hard porous ceramic-like crust under flame exposure
- Exceptional thermal insulation with low thermal conductivity to help prevent heat transfer
- Fire resistance, flame retardancy, ablation resistance, and thermal barrier capability in one material system
- High electrical insulation performance for protected battery and electrical structures
- Environmentally friendly material direction with customized sheet and die-cut support

Informations techniques
Review the product positioning, core data, fire-barrier behavior, application fit, and supply direction for SM150-FG1 foamed silicone rubber.
Q1
What is SM150-FG1 designed for?
SM150-FG1 is designed for ultra-thin fire-barrier, sealing, and insulation applications where the material must behave like silicone rubber at room temperature but convert into a ceramic-like protective crust under extreme heat.
Ultra-Thin Composite Direction
Suitable where the structure needs a very thin material with sealing capability plus thermal-barrier behavior.
Ceramifiable Silicone Behavior
At room temperature it behaves like silicone rubber; under high-temperature flame it sinters into a hard porous ceramic-like crust.
Fire Barrier + Thermal Insulation
Designed to provide fire resistance, flame retardancy, ablation resistance, and an insulating thermal barrier in one material system.
Protection-Oriented Use
Suitable for insulation, sealing, and fire-protection roles in battery packs and charging infrastructure.
Q2
What are the core technical data for SM150-FG1?
The datasheet provides the following values for evaluating fire-barrier capability, electrical insulation, and thin-structure suitability.
| Propriété | Norme d'essai | SM150-FG1 |
|---|---|---|
| Couleur | Visuel | Blanc |
| Épaisseur (mm) | / | 0.3–3.0 |
| Density (kg/m³) | ASTM D3574-95 | 1500 ± 30 |
| Résistivité volumique | JIS C 1302 | >1 × 1014 Ω-cm |
| Rigidité diélectrique | ASTM 149 | >5.0 kV |
| Conductivité thermique | ASTM D5470 | <0.3 W/(m·K) |
| Dielectric Constant | JIS C 1302 | 3.5 F/m |
| Flame Retardancy | UL94 | V0 |
| Tensile Properties | ASTM D412 | 1.7 MPa |
| Tearing Properties | ASTM D412 | 70 |
These values are suitable for early-stage screening. Final suitability should still be validated against the actual fire-barrier, sealing, and assembly conditions.
Q3
What performance strengths does SM150-FG1 emphasize?
The datasheet points to ceramic conversion under high temperature, exceptional thermal insulation, excellent compression resilience, and strong electrical insulation as the core functional directions.
