Vydyne® FR350J

Vydyne FR350J is an unreinforced, flame-retardant PA66 resin designed for unattended appliance electrical connectors. FR350J exhibits best-in-class glow wire ignition temperatures (GWIT) of 960° C at all thicknesses (0.4-3.0 mm) and 800° C with no flame according to UL testing via IEC 60695-2-13. Finished molded parts passed the unattended appliance standard, IEC 60335-1, and achieved GWEPT of 775°C with no flame.

In addition to high GWIT values, Vydyne FR350J is engineered with high elongation and ductility to allow engineers greater design freedom with final molded part geometries. FR350J resin has superior melt flow, reduced mold pressure and reduced cycle time – increasing your production yields while reducing costs.
