• Incombustible Lighting Cover for Trains

    New material FRP

    Passed the combustion test for materials used in railroad vehicles

    Patent protected (transparent incombustible materials and their manufacturing method)

    Patent Number 5589227

  • Does not break! Does not burn! Does not blind!

    EXVIEW is an incombustible and highly optically transparent glass-fiber-reinforced plastic (GFRP).

    Certified as incombustible for use in trains

    Passed the combustion test for materials used in railroad vehicles with no molten drops! (Passed the adaptability test for incombustibility and molten-drop resistance)


    Compared with other materials, EXVIEW shows less deformation and excels with its heat resistance capabilities. It also conforms to flame resistance standards, as certified by the cone calorie meter heat buildup test.

    (Test carried out by the Japan Railway Rolling Stock & Machinery Association)

    Soft diffusion of LED light


    Reaching a total light transmittance of 65% (upper limit)!

    Light source diffusion effect!



    Intricately diffusing the LED source makes it possible to produce a soft light. Also, since transmittance is adjustable, the material can be used as a lighting cover in a variety of environments.


    Multi-use applications

    The shaping mold makes highly flexible, three-dimensionally shaped manufacturing possible. The products can be used in a variety of environments.


    Railroad vehicles/vessels: Lighting cover or interior material in aircraft, cars etc.

    Interior material for buildings: Lighting cover in buildings and hanging fire barriers

    Special uses: Advertising lights, billboard lights, guide lights

    Recommendation comment

    EXVIEW is a new, innovative lighting cover. By combining Miyagi Kasei's FRP technology with the transparent clay film technology held by the National Institute of Advanced Industrial Science and Technology using a new lamination process, we succeeded in creating a never-before-seen material that combines lightness, the high sturdiness of GFRP, incombustibility and transparency. EXVIEW as a material is expected to make a difference not only as a lighting cover in bullet trains and subways, but also in environments where lightweight lighting is essential, such as underground shopping centers, aircraft, etc.

    Manufacturing of FRP (fiber-reinforced plastic) products

    We are involved in the entire production chain, from design and development to trials and mass production.

  • FRP molding techniques​

    Light RTM production molding technique

    After the glass base material is set into the mold, a vacuum is created in the uneven mold to shrink it down. Finally, the resin is inserted via an injecting machine.

  • Infusion​

    The glass base material is set into the mold. Then, using film or similar materials, a vacuum is created and the resin poured in.

  • Hand lay-up/Spray-up​

    After the glass base material is set into the mold, it is impregated with resin using a roller. After removing air bubbles from the installation, the material is laminated.

  • FRP products

    We manufacture products for a variety of fields with our emphasis on interior/exterior panels for cars and related products.
