Nomex IIIA Overalls
(4.5 Ounce Fabric)

Inherently flame Resistant

Nomex IIIA aramid is a permanently, inherently flame resistant and anti-static fiber blend with a unique molecular structure consisting of 93% Nomex, 5% Kevlar and 2% static dissipative fiber. Weighing only 4.5 oz per square yard for lightweight comfort, garments made of NOMEX IIIA will not burn in air, melt, drip or break open and act as a protective barrier when exposed to intense heat, flash fires or electric arcs.

Flame resistant Nomex IIIA suits dissipate electrical charges from fabric to fabric and fabric to surface rubbing, they provides an extra level of comfort against nuisance static, however the only way to protect against other likely sources of sparking is by grounding.

Nomex IIIA fiber blends have good resistance to many chemicals such as organics, acids and bases, but are not designed to protect the wearer against molten chemicals or in critical static control operations.

NOMEX IIIA is widely recognized as a premier fabric providing protection against possible exposure to flame or arc with applications in petrochemicals, utilities, military, auto racing and firefighting. Nomex is inherently flame resistant and this property cannot be degraded by laundering.
