FR Board (Flame-Retardant Board) is specially processed to inhibit or delay combustion when exposed to fire. Unlike ordinary boards that burn easily, these panels can resist ignition, self-extinguish after fire source removal, or slow down fire spread and toxic smoke release.
Meets UL94 V2 rating requirements - self-extinguishes within 10 seconds in vertical burning tests with no dripping that ignites underlying cotton.
- Auxiliary panels for low-voltage electrical equipment including circuit breaker boxes and junction box cover plates
- Internal insulating liners for power distribution cabinets and terminal boxes
- Housings for small electrical components such as low-voltage sensors and terminal blocks
| Advantage | Specific Performance |
|---|---|
| Basic Flame Retardancy | UL94 V2 rating prevents small fires from spreading in low-voltage equipment |
| Electrical Insulation | Volume resistivity up to 10¹⁶Ω*cm, dielectric loss tangent <0.001 |
| Chemical Resistance | Resistant to acids, alkalis, oils, and most coolants/cleaners |
| Lightweight Design | Density of 0.9-0.91g/cm³, 10%-20% lighter than traditional fire-retardant plastics |
| Weather Resistance | Water absorption rate <0.03%, suitable for outdoor electrical boxes |
