Rail TransitVehicle interior
Covering the interior matching of all high-speed trains, subways, light rails, and trams, it complies with EN 45545 Rail Transit fire protection standards and meets Rail Transit strict fire protection, lightweight, and durable operation standards.
●Car interior area: the car ceiling, wall filling, and interior partitions simultaneously achieve sound insulation, noise reduction, and fire protection. Lightweight materials reduce the weight of the vehicle.
●Cabin and vestibule: Customized special-shaped sound-absorbing components to reduce wheel-rail friction and noise reflection from vehicle-mounted equipment, optimizing the driver and passenger operating environment
●Vehicle HVAC system: Pipe moldings made of hydrophobic special melamine sponge, which isolates water vapor erosion, maintains stable sound absorption and flame retardant properties for a long time, and is suitable for vehicles with year-round vibration and alternating temperature differences.
●Vehicle equipment cabin: various electrical control cabinets and air-conditioning unit linings to isolate high temperatures, suppress equipment noise, and have flame retardant properties to avoid the risk of circuit fires
Technical parameters
performance dimension | Core parameters | illustrate |
Sound absorption and noise reduction | NRC ≥ 0.85 | Broadband and efficient sound absorption, opening rate 99.9% |
Thermal insulation | Thermal conductivity 0.035 W/(m·K) Airgel model≤0.015 W/(m·K) | Better than traditional rock wool/glass wool |
Flame retardant safety | UL94 V-0 /B1 level | Intrinsically flame retardant, self-extinguishing when removed from fire, no droplets and low smoke |
Lightweight | Density 8-12 kg/m³ | 5-10 times lighter than traditional materials, reducing structural load |
Temperature resistance range | -160℃ ~ +240℃ | Stable performance in extreme temperature environments |
