Abstract:
1. A method for preparing a coated fabric which comprises (I) applying a vulcanizable elastomer composition to a layer of fabric, wherein the vulcanizable elastomer composition is made by a method comprising the steps of: (1) mixing a cross-linkable functionalized polyethylene with at least one cross-linkable liquid elastomer to form a non-reactive extrudant, wherein the mixing occurs at a temperature in the range of 10° F. above or below the melt point of the cross-linkable functionalized polyethylene, and wherein the non-reactive extrudant contains from 20 to 80 parts per hundred of the cross-linkable liquid elastomer, (2) extruding the non-reactive extrudant, and (3) mixing the extrudent with at least one curing agent, wherein the mixing is sufficient to form the vulcanizable elastomer, and wherein the vulcanizable elastomer has a complex dynamic viscosity of less than 5 McP (5,000 N*s/m 2 ) for at least 2 minutes at a maximum flow temperature; and (II) heating the layer of fabric having the vulcanizable elastomer applied thereto to a temperature which is within the range of 200° F. to 310° F. for at least 2 minutes to produce the coated fabric.
