Abstract

The invention relates to a protective plastic film or sheet for use in protecting against smoke, heat, corrosive liquids and other hazardous elements. The sheet comprises a fire resistant substrate layer having a primary surface, a layer of titanium covering a major portion of the primary surface of the substrate layer, and a plurality of perforations extending through the polyimide and titanium layers. The perforations allow passage of moisture vapor while the film or sheet provides protection against exposure to smoke, heat, corrosive liquid and other hazardous elements. Also disclosed is equipment for use by emergency personnel made from such plastic films or sheets.

Claims

AMENDED CLAIMS[received by the International Bureau on 18 October 2000 (18.10.00); original claims 1-10 amended; remaining claims unchanged (2 pages)]
1. A protective plastic film or sheet for use in protecting against smoke, heat, corrosive liquids and other hazardous elements, comprising:
a. a fire resistant substrate layer having a primary surface;
b. a layer of titanium that reflects thermal radiation and resists corrosive chemicals, the layer covering a major portion of the primary surface of the substrate layer; and
c. a plurality of perforations extending through the substrate and titanium layers,
whereby the perforations allow passage of moisture vapor while the film or sheet provides protection against exposure to smoke, heat, corrosive liquid and other hazardous elements.
2. The protective film or sheet of claim 1, whereby the titanium layer covers the entirety of the primary surface.
3. The protective film or sheet of claim 1, comprising a second layer of titanium covering a major portion of a second surface of the substrate layer, and the perforations also extend through the second layer of titanium.
4. The protective film or sheet of claim 1, wherein the titanium layer has a thickness between about 100 to 1000 angstroms.
5. The protective film or sheet of claim 1, whereby the substrate layer comprises a thermoset plastics material.
6. The protective film or sheet of claim 5, whereby the substrate layer comprises a polyimide.
7. The protective film or sheet of claim 1, further comprising an additional layer permeable fibrous backing material.
8. The protective film or sheet of claim 1, whereby the perforations have diameters in the range of about 0.1 to 10 microns.
9. The protective film or sheet of claim 1, whereby the substrate has a thickness in the range of about 25 to 75 microns.
10. Emergency equipment for use by firefighters or other emergency personnel to protect against smoke, heat, corrosive liquids and other hazardous elements, the emergency equipment comprising a protective film or sheet comprising:
a. a fire resistant substrate layer having a primary surface;
b. a layer of titanium that reflects thermal radiation and resists corrosive chemicals, the layer covering a major portion of the primary surface of the substrate layer; and
c. a plurality of perforations extending through the substrate and titanium layers,
whereby the perforations allow passage of moisture vapor while the emergency equipment provides protection against exposure to smoke, heat, corrosive liquid and other hazardous elements.
11. The emergency equipment of claim 10, whereby the titanium layer covers the entirety of the primary surface.
12. The emergency equipment of claim 10, comprising a second layer of titanium covering a major portion of a second surface of the substrate layer, and the perforations also extend through the second layer of titanium.
13. The emergency equipment of claim 10, wherein the titanium layer has a thickness between about 100 to 1000 angstroms.
14. The emergency equipment of claim 10, whereby the substrate layer comprises a thermoset plastics material.
