Nomex®* is extremely heat resistant. It will not char at
temperatures lower than 675° Fahrenheit. This
makes it extremely desirable in safety garments used in potentially high
heat applications.
Decomposition: Begins to decompose at about 700°
Fahrenheit.
Melting Point: Does not melt.
Effects of Acids & Alkalis: Unaffected by most acids, except some
strength loss after long exposure to hydrochloric, Sulphuric, and nitric
acids. Generally good resistance to alkalis.
Effects of Mildew, Aging, Sunlight & Abrasion: Excellent resistance
to mildew and aging. Prolonged exposure to sunlight causes some strength
loss. Good abrasion resistance.
