Rail Interior Applications


  • Door Seals

    kSil™V-0 provides the sealing protection needed for rail carriage door seals. With its low compression set and dimensional stability, kSil™V-0 ensures excellent sealing performance lasting throughout the train’s lifespan.

  • HVAC Seals & Gaskets

    HVAC systems within rail carriages are designed to withstand heat fluctuations and varying degrees of vibration. kSil™V-0 has been specially formulated to withstand extreme temperatures from -60°C to +230°C, whilst sealing to IP66.

  • LED Lightning Gaskets

    LED lighting enclosures need to be protected from a range of elements from water, dust and moisture to high temperatures, which is why kSil™V-0 is formulated to protect from all of them. Its closed cell structure prevents water, dust and moisture ingress to IP66.

  • Flooring & Gangways

    kSil™V-0 provides excellent vibration and acoustic dampening as well as low compression set properties for rail flooring. Due to its compact, closed cell structure, kSil™V-0 effectively absorbs vibration and provides protection to train flooring systems.
