Choosing PrimePart FR (PA 2241 FR)
A halogenated flame-retardant EOS PA12 for aircraft-interior parts where its stated FAR/JAR/CS test configuration matches the qualification plan.
- Consider it for
- Aircraft-interior ventilation ducts · Exhaust valves and interior brackets · FR prototypes using the specified EOS SLS route
- Tradeoffs
- The source ties flammability, smoke and toxicity results to stated specimen thicknesses and methods. Those material results do not certify a finished component, assembly or installation.
- Design and validation
- Record wall thickness, orientation, conditioning, finish and the exact required aerospace test. Build the part-level compliance plan before release to production.
- Finishing
- White is the as-printed colour and this catalog row is not dyeable. Any coating, marking or cleaning step changes the tested configuration and must be reviewed in the qualification plan.
- Before choosing
- Which exact aerospace standard, thickness and installed configuration governs? Is halogen-based PA2241 FR acceptable for the program, or is another FR chemistry required?
