Silicone-Coated vs. Fiberglass: Choosing the Right Material for Vehicle Fire Blankets
As electric vehicles (EVs) become more prevalent in commercial fleets and parking structures, the demand for effective fire suppression has shifted. For procurement managers and safety engineers, the core question is: Which material will hold up under the 1000°C+ heat of a lithium-ion battery fire?
1. Standard Fiberglass: The Baseline
Fiberglass is the traditional choice for general fire safety. While non-combustible, standard fiberglass has a temperature limit of approximately 550°C – 600°C. In the event of a “thermal runaway” in an EV battery, these temperatures are exceeded almost instantly, causing standard fiberglass to become brittle and fail.
2. Silicone-Coated Advantage: 1000°C+ Protection
By applying a specialized technical silicone layer over high-silica fiberglass, the blanket’s performance is transformed. High temperature fire blankets for EV fires must act as a containment cell, preventing oxygen ingress and containing toxic smoke. Silicone coating provides the structural integrity needed to survive 1000°C+ peaks.
3. Material Comparison
| Feature | Standard Fiberglass | Silicone-Coated |
|---|---|---|
| Max Temp | ~600°C | 1000°C – 1300°C |
| Gas Sealing | Porous (Leaks smoke) | Gas-tight Barrier |
| Durability | Low (Fibers break) | High (Abrasion resistant) |
