Abstract
An arc flash resistant material includes a para-aramid non-woven material substrate and a polyurethane film containing approximately 10-40% by weight of antimony oxide (Sb2O3, Sb2O5) and decabromodiphenyl oxide containing a high level of aromatic bromine laminated to a first surface and a second surface of the para-aramid non-woven material substrate. The arc flash resistant material may be breathable and include antistatic properties. The arc flash resistant material is light weight, exhibits an exceptionally high level of protection from an arc flash hazard, and possesses a low particulate level that is required for clean room applications.

An arc flash resistant material comprising:
- an arc flash resistant non-woven material substrate;
- and
- a flame-resistant polyurethane film laminated to a first surface and a second surface of the non-woven material substrate, wherein the flame-resistant polyurethane film comprises a polyurethane containing 10-20% antimony oxide (Sb2O3, Sb2O5) and decabromodiphenyl oxide containing a high level of aromatic bromine.
An arc flash resistant material comprising:
- a para-aramid non-woven material substrate;
- and
- a polyurethane film containing approximately 10-40% by weight of antimony oxide (Sb2O3, Sb2O5) and decabromodiphenyl oxide laminated to a first surface and a second surface of the para-aramid non-woven material substrate.
An arc flash resistant material comprising:
- a para-aramid non-woven material substrate weighing approximately 1.5 ounces per square yard (oz/yd2);
- and
- a polyurethane film containing approximately 10-40% by weight of antimony oxide (Sb2O3, Sb2O5) and decabromodiphenyl oxide laminated to a first surface and a second surface of the para-aramid non-woven material substrate, wherein the polyurethane film is configured to enable the passage of moisture.
