NOMEX® Type 418 is designed for high-voltage applications, including motor conductor and coil wrap, transformer ground and layer insulation. It is a calendered product with high inherent dielectric strength (30 to 40 kV/mm), which can be readily impregnated with varnishes where this is desirable. NOMEX® Type 418 is available in 5 thicknesses,  from 0.08 to 0.36 mm (3 to 14 mil). This calendered blend of aramid and mica offers increased voltage endurance over NOMEX® Type 410 when subjected to corona attack. NOMEX® Type 419 is the uncalendered precursor of NOMEX® Type 418, and is available in two thicknesses, 0.18 and 0.33 mm (7 and 13 mil). NOMEX® Type 419 is used in applications which take advantage of the lower density (0.5) which allows improved conformability and saturability
