EN45545 Fire-Safe Silicone Profiles & Tubing for Railways
Every polymer part in a rail vehicle has to pass fire, smoke and toxicity rules. For seals, gaskets and cable protection, that means compounds tested to EN45545-2 at the hazard level the car requires.
Centroid extrudes and moulds silicone profiles, sheets and packings from EN45545 HL3-certified compounds for metro, high-speed, sleeper and passenger rolling stock. We also supply fire-retardant self-fusing silicone tape and cold-shrink tubing for cable work in locomotives and along the track.
We support rolling-stock builders and their tier suppliers with custom profiles, small pilot batches and documentation for homologation.
What Railways & Metro buyers need
- EN45545-2 HL3 compliant compounds with test reports
- Low smoke density and low toxicity in fire
- Weathering and vibration resistance for exterior and underframe use
- Custom door, window and panel profiles to car-builder drawings
- Cable sealing that installs without heat in confined spaces
Standards commonly specified
- EN45545-2 HL3
- NFPA 130
- RDSO approvals (on request)
Compliance varies by product and compound. Ask us for the certificates and test reports for your part.

Frequently asked questions
What does EN45545 HL3 mean?
EN45545-2 sets fire-behaviour requirements for railway materials. HL3 is the highest hazard level, required for vehicles such as underground metros and sleeper cars where evacuation is hardest.
Can you supply test reports for homologation?
Yes. We share compound certification and test documentation for EN45545 parts on request.
Do you make custom door and window seals for trains?
Yes. Send us the profile drawing and we will extrude or mould it from a certified compound.
Need a custom part for railways & metro?
Send a drawing or sample and our engineers will recommend a compound and quote.
