Abstract: A composite laminate comprising at least one moisture vapor permeable nonwoven sheet having first and second surfaces and a fluorinated polymeric coating on the first surface of the sheet wherein (i) the fluorinated polymeric coating is present in an amount such that the total fluorine content of the coated non-woven sheet is 0.05 to no greater than 0.4 gsm, and (ii) the composite laminate, after exposure to wet timber, exhibits a retained hydrohead of at least 60 percent.

Abstract: A system for protecting temperature sensitive products. The system comprises a cover that fits over a product. The cover has a first component, a second component, and a closure system. The first component covers the top of the product and at least a portion of a first side of the product, and the second component covers at least a portion of the other sides of the product. The closure system closes openings between the first component and the second component and tightens the cover around the product. The cover is removable from the product by releasing the closure system and pulling the second component of the cover in a horizontal or downward direction away from the first side of the product.

Abstract: The present invention is directed to a separator for an electrochemical cell comprising a web, the web comprising fibers of a polyimide and a protective region wherein the protective region impedes electrochemical reduction of the polyimide inside the electrochemical cell. The present invention is further directed to a multi-layer article and electrochemical cell containing the separator.
