Low Smoke Flame Retardant Filament

Certified for use in railway 

PA6/66-GF20 FR LS Low Smoke is one of few commercial filaments that meets norms EN 45545-2, NFPA 130 (ASTM E162, ASTM E662), SMP 800-C and FAR 25.853. Its certifications for flame, smoke and toxicity (FST) make it suitable for railway and other transportation applications.

The Low Smoke filament is a cost-efficient and easier-to-print solution for applications that need to meet European and North American railway norms. The innovative material can be printed easily on standard filament printers, eliminating the need for high temperature printers.

The proprietary formulation uses a non-halogenated flame retardant with a reduced ecological impact, and the composition has been optimized to avoid typical smoke development and achieve the low smoke requirement of the European and North American standards.

The glass filled material performs at high temperatures.

Applications

  • Electrical in-train parts such as connectors, covers or enclosures, outlet boxes, panels
  • Small electrical components such as cable guides,  reading lights
  • Other internal and external train applications, also visible parts
  • Aerospace components
