Nomex case lining

Description

[DuPont] A registered trademark for a meta-aramid fiber that was originally developed in the 60s for fire/electrical insulation applications. Nomex fibers are composed of poly(m-phenylene isophthalamide), which is made from m-phenylene diamine and isophthalic acid. The fibers have excellent dielectric, thermal and mechanical properties and are resistant to fire, water, and biological growth. They retain their properties at temperatures up to 370C (700F). Nomex fibers are available as both woven and nonwoven fabrics. Due to its fire resistance, Nomex fabrics are used in fire fighters clothing, military flight suits and other applications in the space program. Soft forms of Nomex are used for as a lining material in packing museum objects. Nomex can also be laminated then expanded to form the lightweight core in honeycomb structural boards.

Applications

  • Lining cavities cut in foam
  • Cane be sewn and bonded with hot melt adhesives without melting

Health and Safety

Fire resistant and self-extinguishing. Degrades in ultraviolet light. May be susceptible to snagging on corners.

Sustainability Factors

Physical and Chemical Properties

Resistant to acids, alkalis, bleaches and most solvents. Fiber is smooth. Permeable to air and moisture. Fiber cross section = dogbone.

Working Properties

The spunwoven version of Nomex is typically used in museum applications. It has the unique ability to stretch in one direction, preventing bunching and folding of loose material within a cavity (PACCIN).

Sizes and Forms

Forms include fibers, paper/fabric, felts, and rigid honeycomb boards. Flexible fabric typically comes rolls with widths of 39”. Thicknesses range from 3 to 30 mils.
