Applications: The paper is used in electrical laminates such as circuit boards and transformer cores as well as fireproofhoneycomb structures where it is saturated with a phenolic resin. Honeycomb structures such as these, as well asmylar-Nomex laminates are used extensively in aircraft construction. Both the firefighting and vehicle racing industries use Nomex to create clothing and equipment that can withstand intense heat. A Nomex hood is a common piece of racing and firefighting equipment. It is placed on the head on top of afirefighter's face mask. The hood protects the portions of the head not covered by the helmet and face mask from the intense heat of the fire. Race car drivers wear driving suits constructed of Nomex and or other fire retardant materials, along with Nomex gloves, long underwear, balaclavas, socks, and shoes to protect them in the event of a fire. The FIA and the SFI Foundation provide specifications for flame-resistant drivers clothing to be used in racing. The standards range from single layer suits that provide some protection against flash fires to much thicker multilayer SFI-15 suits required by the National Hot Rod Association that can protect a driver for up to 30 seconds against the intense heat and almost invisible flames generated by the nitromethane, ethanol and methanol fuels that are used in championship drag racing (straight line acceleration contests)
