Rail transportation has extremely high requirements for interior materials regarding lightweighting, fire safety, environmental friendliness (non-toxic), and durability. PP Honeycomb (especially flame-retardant FRPP grade) is an ideal choice:
- Interior Wall and Ceiling Panels: Forms the core of sandwich panels for carriage sidewalls, end walls, and passenger compartment ceilings. Significantly reduces vehicle weight, aiding energy savings and speed; its flat surface facilitates decorative fabric application; the honeycomb structure also contributes to excellent noise reduction, enhancing passenger comfort.
- Seats and Luggage Racks: Used for seat back and pan frames, luggage rack backer boards, and base panels. Lightweighting reduces vehicle mass, high stiffness ensures load-bearing capacity, and fatigue resistance guarantees long service life.
- Driver Consoles and Control Cabinets: Fabrication of driver dashboard panels, electrical cabinet bodies. The material is insulating, moisture-proof, and dimensionally stable.
- Toilet and Kitchen Modules: Flooring, wall panels, and cabinet bodies for integrated bathrooms. PP honeycomb is completely waterproof, resistant to cleaning agents, inhibits bacterial growth, is lightweight, and facilitates modular installation.
- Door and Window Interior Panels: Door interior panels and window sill liners.
All PP honeycomb used in rail transportation must comply with stringent fire (e.g., EN45545, DIN5510), smoke toxicity, and heat release standards, necessitating the use of certified, specialized flame-retardant grades.
