EN45545 Halogen-Free PA（EN45545 无卤 PA）

EN45545 Halogen-Free PA:High-Performance, Eco-Friendly Nylon for RailSafety

EN45545 halogen-free PA(polyamide) is a next-generation engineering plasticengineered to meet the stringentEN45545-2:2020+A1:2023 fire safety standards forrailway vehicles. By eliminating halogens (e.g., chlorine, bromine)from its formulation, this material combines exceptionalflame retardancy, mechanical strength, and environmentalsafety with low smoke and non-toxic emissions. It is anideal choice for critical rail applications such aselectrical housings, connectors, structural components, andhigh-load bearings, where fire resilience, durability, andsustainability are paramount.

Shanghai KZL ChemicalCo., Ltd. is a trusted supplier of EN45545 halogen-freePA, offering certified materials with S G S-verifiedcompliance to ensure safety, reliability, and regulatoryalignment for global rail projects.

Key Features of EN45545Halogen-Free PA

1. EN45545-2:2020+A1:2023Certified

   
   

2. Flame retardantperformance: Achieves UL94 V-0 or V-2(formulation-dependent) with zero halogen content,ensuring controlled flame spread and minimizing fire risks inhigh-risk areas (e.g., electrical cabinets, enginecompartments).

   
   

3. Smoke & toxicitycontrol: Ultra-low smoke density (EN 45545-2 Annex D) andno hazardous halogenated gases, reducing toxicemissions (e.g., CO, HCN) to protect passengers duringevacuations.

   
   

4. Materialclassification: Compliant with R1–R28 usagecategories (e.g., R12 for electrical components, R27 fordisplay covers) and HL1–HL3 risklevels.

   
   

5. Superior Mechanical &Thermal Properties

   
   

6. High tensilestrength (≥80 MPa) and rigidity, ensuringdimensional stability under mechanical stress and temperaturevariations.

   
   

7. Excellent wear andabrasion resistance, ideal for high-load bearings andstructural parts.

   
   

8. Thermalstability (HDT ≥150°C), suitable for demandingenvironments like engine rooms and power systems.

   
   

9. S GualityAssurance

   All EN45545 halogen-free PA fromShanghai KZL Chemical are backed by S G S-certified testreports, providing independent verification of:

   
   

10. Flame spread, smoke density, andtoxicity indices.

    
    

11. Mechanical properties (tensilestrength, impact resistance).

    
    

12. Compliance with EN45545-2, RoHS(halogen-free), and REACH regulations.

    “S G S certificationguarantees transparency, ensuring your materials meet the highestsafety and environmental benchmarks.”

    
    

13. Eco-Friendly &Customizable Solutions

    
    

14. Halogen-free andadditive-free formulation avoids environmental and healthrisks associated with traditional halogenated flameretardants.

    
    

15. Available with glassfiber or mineral reinforcement for enhanced strength andheat resistance.

    
    

16. Customizable forlightweighting, conductivity, or chemicalresistance to meet diverse rail applicationneeds.
