Nylatron® 66 SA Flame Retardant (FR) Polyamide PA66 shapes were developed to fulfill the requirements of the plastic flammability test, which determines the tendency of the material to either extinguish or spread the flame once the it has been ignited. This test procedure is described in UL 94, and this particular Nylatron® grade fulfills the V-0 criteria from a thickness of 1 mm, while also meeting the requirements of EN 45545-2 regulation- a standard specific to railway applications. For these reasons, Nylatron® SA FR PA66 components are often favored solutions for applications within the transportation and railway markets such as, cable holders, clamps, and channels, and connections / sockets.
