NOMEX® by Dupont
Maximum value for your money
 
Nomex is the internationally recognized, time-tested and trusted workhorse fibre for thermal protection. This fabric is inherently flame resistant and contains a self extinguishing meta-aramid. Although low in weight Nomex has high tensile strength and is unaffected by most acids.

Shield gives you the assurance of all-around quality and authenticity of materials through:

•  Manufacturing specifications
•  Certification of materials (fabric and all accessories)
•  Traceability to source and throughout production

At the end of the day, you will be fully protected by International Standard certification.
 

 
Features and Applications  
 
Details
Nomex is an aramid fiber manufactured by Dupont. For clothing applications, it is usually blended, by KEVLAR with another Dupont aramid. A blend of 95% NOMEX and 5% KEVLAR called NOMEX III was offered for many years. To address concerns of nuisance static electricity generated on NOMEX III, IIIA, a blend of 93% NOMEX, 5% KEVLAR and 2% static dissipative fiber was introduced.
 
Applications
Petrochemicals, utilities, military applications, auto racing, volunteer and professional fire fighters. NOMEX is offered in woven, knit, and fleece fabrications.
 
Not Recommended For
Use around any molten substance, welding operations, or in a critical static control application.
 
Flame Resistance
NOMEX is inherently flame resistant and this property cannot be degraded by laundering.
 
Colors
Dye able in a wide range of colors with mixed colorfastness to laundering some shades good, some fair.

Also available in a solution dyed foam where fiber dyed in the fiber forming process. This limits color selection, but provides improved color fastness at increased cost.
 
Effect of Acids and Alkalis
NOMEX is unaffected by most acids, except for some strength loss after long exposure to hydrochloric, citric and sulphuric. It has generally good resistance to alkalis.

Effect of Bleaches and Solvents the fiber is unaffected by most bleaches and solvents, except for slight strength loss form exposure to sodium hypochlorite bleach. However the fabric does not provide personal chemical protection to the wearers. Where chemical exposure is a hazard, appropriate specialized barrier garments, should be selected.
 
Effect of Mildew, Aging, Sunlight and Abrasion
NOMEX has excellent resistance to mildew aging and abrasion. Naturally (undyed) NOMEX is not white and will yellow with exposure to sunlight. Accordingly, some lighter dyed shades will discolor rapidly. These lighter shades are available in solution dyed form.
 
Thermal Stability
NOMEX has good thermal stability and does not melt. The fiber decomposes between 700 - 800F. NOMEX is inappropriate and not recommended for use around any molten substances or welding operations. Hot molten contact will stick to the fiber, forming holes.
 
Moisture Regain / Static Control
Moisture regain is moderate compared to other synthetic flame resistant fibers, but only about 70 of cotton.

Nuisance static has been a perceived problem of NOMEX, IIIA addresses this concern. Antistatic performance of NOMEX IIIA is not dependent on ambient relative humidity. It is important to recognize that NOMEX IIIA is designed to combat nuisance static only and, like 100% cotton, it should not be considered for use in critical static control applications.
 
Processing
For best color retention, laundry processing should be carried out at 140 F or less in buffered, nonionic detergents. However, higher temperature / harsher detergent laundering will only affect the color, not the performance of the fabric. NOMEX garments may be dry cleaned in either perchlorosthylene or petroleum solvents. They may be conditioned or tunnel finished at up to 280F fabric temperature.
 
Garment Cost
Garments of NOMEX IIIA cost about five times as much as conventional 65% polyester / 35% cotton and about 2 times more than FR cotton.
 
Garment Life
Under normal wear conditions as long as 3 – 5 years or 2 – 3 times the life of conventional 65% polyester / 35% cotton and 3-5 times the life of FR cotton.

NOMEX IIIA is extremely durable and can be expected to perform well for many years in applications where longevity can be utilized.
 
.............................................................................................................................................................................................
 
For more than 30 years, protective apparel made from DuPont NOMEX® aramid fiber has provided superior protection from the heat and flame of flash fires. Garment of NOMEX® IIIA help protect workers in the petroleum, petrochemical, checimal, and electricand gas utility industries.
