Fire-resistance standards almost always apply to the composite parts used in rolling stock, public transport or construction works. Different countries may follow diferent standards for fire
retardancy, and material selection should be made accordingly.
Fire-retardant composite material can be made using special resins, fillers or coatings. For the parts made by manual moulding or closed moulding, we recommend using a fire-resistant gelcoat and a resin that work together.
Examples of application:
1. locomotive masks 2. operator’s panels 3. rolling stock interior parts 4. train and tram seats 5. toilet modules
