Nylatron™ FST PA66 nylon shapes are fire, smoke and toxicity retardant, which enables them to withstand extreme temperatures up to 175°C (347°F). In addition to these characteristics, Nylatron™ FST PA66 is also JAR/FAR 25.853 compliant. As the first engineering plastic to achieve this standard, this polyimide grade was developed specifically for use in aircraft interior environments. Additionally, the material is often favored as a replacement for metal parts applications such as brackets, seal bushings, slide rails and duct seals.
