2.  Nomex is an inherently flame-resistant, high-temperature resistant fiber that will not
melt, drip, or support combustion in air. Nomex is a one kind of high-performance fiber.
 Nomex is the brand name of a heat and flame resistant textile made by the DuPont
Chemical Company.
Fiber type: Synthetic fiber
Source: Aramid
Characteristics: Chemical resistant, Electrical resistant, Fire resistant
Typically used in: Glove, Trousers, Shoe, Shirt, Hood, Balaclava
Parent company: DuPont

3.  Nomex was first created back in the early 1960s but would be marketed in 1967. Dr. Wilfred
Sweeney created it in the now world-renowned DuPont laboratory. Nomex’s technical name
is ‘Synthetic Aromatic Polyamide Polymer’.
 In early 1966 Competition Press and Auto week reported: "During the past season, experimental
driving suits were worn by Walt Hansgen, Masten Gregory, Marvin Panch and Group 44's Bob Tullius.

4. The properties of Nomex include great electrical insulation properties at high temperatures.
The general properties of Nomex are listed below.
 Heat and Flame Resistant
 High Ultraviolet Resistance
 High Chemical Resistance
 Low Thermal Shrinkage
 Formable for Molded Parts
 Low Elongation to Break
 Low Electrical Conductivity

6.  The chemical name of Nomex is poly (m-phenylenediamine isophthalamide), which is
produced from the reaction of m-phenylenediamine and isophthaloyl chloride whose
structures are shown below :
