Covestro Addigy® PA6/66-GF20 FR LS
Validated FDM Thermoplastic
Addigy® PA6/66-GF20 FR LS is a glass-filled nylon material designed for FDM additive manufacturing applications in the railway and aerospace industries. This flame-retardant Stratasys Validated Material has low smoke generation characteristics, and its glass-filled composition provides excellent thermal performance at elevated temperatures.
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.
