Railway Rolling Stock
The requirements for the fire protection of railway rolling stock were very diverse, but under EN45545-2 the test procedures and classification within Europe are being harmonised.
The risk to life and escape times for railways and trams vary a great deal depending on what proportion of time the train spends in tunnels.
Clearly, the level of smoke emission and toxicity of a fire in a contained space is a major hazard. With the drive to lighter more efficient structures the low smoke low toxicity Phyrolex flame retardants can make a major contribution to lightweight structures.
Typical resin systems that have been investigated for use with Phyrolex are:
- Polyester: Phyrolex HMED and MDD offer excellent results with significant smoke reduction. When used in SMC and BMC products it is possible to achieve flame retardancy with far lower loading of FR- a Phyrolex HMED loaded SMC has achieved a HL2 with a 35% weight saving over ATH.
- PU coatings for composites and aluminium: Phyrolex HMED produces excellent coatings to flame retard these substrates.
- Polysiloxane sealants: Phyrolex HMED produces excellent flame retardant and fire protective cold curing sealants
- Latex based resins for use on carpet backing and seat covers- Phyrolex HMED disperses into latexes and offers excellent protection.
- Rubber flooring: Phyrolex HMED provides good fire protection when used in this application
- Phyrolex HMED can provide excellent fire protection to rubber flooring.
- Phyrolex PCP can create outstanding coatings for protecting seat fabrics including thermoplastic types.
- Phyrolex HMED can produce excellent rigid and flexible foams for passing any fire test including the CRIB 7 seat test.
- Phyrolex PPEs can create outstanding phenolic foams and composite panels that can provide upto 60 minute bulkhead protection.
- Phyrolex PCP can create outstanding two pack varnishes and coatings with class leading performance- our ready to go coatings have been Certified to HL3 under EN45545-2 for timber, epoxy and polyester, as well as achieving a Cat 1A under BS6853 on epoxy prepregs. In addition they have shown to be able to create up to 30 minute barrier panels under EN1381 on timber, epoxy and polyester.
