Abstract
The invention is directed to a method of forming an annular component useful as an air barrier comprising wrapping a sheet around a building drum to create an annular component having overlapping opposing edges thereby forming an overlapping seam, the sheet having a modulus as determined according to ASTM D412-92 greater than about 6.5 MPa, wherein the edges of the seam are modified prior to wrapping.
Claims25
A method of forming an annular component useful as an air barrier comprising wrapping a sheet around a building drum to create an annular component having overlapping opposing edges thereby forming an overlapping seam, the sheet being a blown or cast film of a dynamically vulcanized alloy and having a modulus as determined according to ASTM D412-92 greater than about 6.5 MPa,
- wherein the edges of the sheet are modified prior to wrapping.

An article comprising an annular component useful as an air barrier, the annular component having a modulus as determined according to ASTM D412-92 greater than about 6.5 MPa,
- wherein the annular component has an overlapping seam and the gauge of the component at the overlapping seam is equivalent to the average gauge of the component.
A method of forming an annular component useful as an air barrier comprising wrapping a sheet around a building drum to create an annular component having overlapping opposing edges thereby forming an overlapping seam, the sheet formed from a dynamically vulcanized alloy and having a modulus as determined according to ASTM D412-92 greater than about 6.5 MPa,
- wherein the total thickness of the sheet at the overlapping seam is reduced from greater than or equal to about 2x to about x, where x is an average total thickness of the sheet, and wherein the edges of the sheet are modified prior to wrapping.
