Abstract
A seam tape, patch material, accessory material, or component material may be used for an inflatable safety product. The seam tape, patch material, accessory material, or component material includes an emissivity of less than or equal to 0.48. An inflatable safety product or an accessory for an inflatable safety product may include the seam tape, patch material, accessory material, or component material.
Claims21
An inflatable safety product comprising a fabric or flexible composite material as a seam tape, patch material, accessory material, or component material, wherein the fabric or flexible composite material comprises an emissivity of less than or equal to 0.48 and a radiant heat resistance of at least 180 seconds, when exposed to radiant heat flux of 1.5 Btu/ft2-sec or greater, for at least 180 seconds, wherein the fabric or flexible composite material comprises:
- a substrate having opposing surfaces, the substrate comprising polyethylene, ultra-high molecular weight polyethylene, polypropylene, polyamide, aromatic polyamide, polyarylate, or a liquid crystal polymer;
- a metallic layer covering at least one of the opposing surfaces of the substrate;
- and
- an intermediate layer between the substrate and the metallic layer, wherein the intermediate layer is adhesive layer and/or a film layer.
An inflatable safety product comprising a fabric or flexible composite material, the fabric or flexible composite material comprising:
- a substrate;
- and
- a metallic layer covering at least one surface of the substrate,
- wherein an emissivity of the fabric or flexible composite material is less than or equal to 0.48,
- wherein the fabric or flexible composite material comprises a radiant heat resistance of at least 180 seconds, when exposed to radiant heat flux of 1.5 Btu/ft2-sec or greater, for at least 180 seconds, and
- wherein the substrate comprises at least one of polyethylene, ultra-high molecular weight polyethylene, polypropylene, polyamide, aromatic polyamide, polyarylate, or a liquid crystal polymer.
A method of joining panels of an inflatable safety product, the method comprising adhering or welding a first panel and a second panel in a seam region formed by the first panel and the second panel using a seam tape, wherein:
- the seam tape comprises a substrate and a completely covering metallic layer covering at least one surface of the substrate;
- the substrate comprises polyethylene, ultra-high molecular weight polyethylene, polypropylene, polyamide, aromatic polyamide, polyarylate, or a liquid crystal polymer;
- and
- the seam tape comprises an emissivity of less than or equal to 0.48, wherein the seam tape comprises a radiant heat resistance of at least 180 seconds, when exposed to radiant heat flux of 1.5 Btu/ft2-sec or greater, for at least 180 seconds.
An inflatable safety product comprising a fabric or flexible composite material as a seam tape, patch material, accessory material, or component material, wherein the fabric or flexible composite material comprises an emissivity of less than or equal to 0.25 and a radiant heat resistance of at least 180 seconds, when exposed to radiant heat flux of 1.5 Btu/ft2-sec or greater, for at least 180 seconds, wherein the fabric or flexible composite material comprises:
- a substrate having opposing surfaces, the substrate comprising polyethylene, ultra-high molecular weight polyethylene, polypropylene, polyamide, aromatic polyamide, polyarylate, or a liquid crystal polymer;
- a metallic layer covering at least one of the opposing surfaces of the substrate;
- and
- an intermediate layer between the substrate and the metallic layer, wherein the intermediate layer is adhesive layer and/or a film layer.
