Benefits of Addigy PA6/66-GF20 FR LS

From a regulatory perspective, Addigy PA6/66-GF20 FR LS meets the following transportation safety standards:

  • EN 45545 – European fire protection standards for railway vehicles.
  • NFPA 130 – Fire protection standard for underground, surface, and elevated transit and passenger rail systems.
  • SMP 800-C – Bombardier standard for toxic gas generation.
  • FAR 25.853 – FAA standard for flammability ratings associated with aircraft compartment interiors.
Non-Toxic and No Harmful Gasses

This material also uses non-halogenated flame retardant, which is non-toxic and does not release harmful gasses. Non-halogenated additives are also an environmentally greener alternative and are not subject to regulation. 

Faster, Lower-Cost Alternative

Addigy PA6/66-GF20 FR LS FDM filament offers a faster, lower-cost alternative to molding and machining to replace obsolete parts and support other low-volume production applications, particularly in regulated industries.
