Patent ID: 8104519

Claim:
A pipe insulation product comprising: a tubular core of insulating material, the tubular core comprising: a length and a longitudinal axis; a substantially cylindrical outer surface; a substantially cylindrical inner surface; and a wall extending between the cylindrical outer surface and the cylindrical inner surface, the wall of the tubular core having a radially extending thickness, the wall of the tubular core having a slit extending completely there through, the slit extending parallel to the longitudinal axis of the tubular core for the length of the tubular core; a laminate that is roughly rectangular in shape and that is coextensive with and bonded to the substantially cylindrical outer surface of the tubular core and flexible so that the tubular core and laminate can be opened, placed about a pipe, and closed without degrading the laminate, the laminate comprising: a foil or metallized polymeric film sheet layer forming an inner layer of the laminate, wherein the foil or metallized polymeric film sheet layer is bonded to the substantially cylindrical outer surface of the tubular core, and wherein the foil or metallized polymeric film sheet layer provides a fluid vapor barrier to minimize fluid vapor transmission through the laminate; a scrim comprising a mesh of a plurality of fibers; a porous media sheet layer, wherein at least one of the scrim and porous media sheet layer provide reinforcement for the laminate; a polymeric film sheet layer forming an outer exposed layer of the laminate; and an adhesive, wherein: the adhesive bonds the foil or metallized polymeric film sheet layer, the scrim, the porous media sheet layer, and the polymeric film sheet layer together to form the laminate, and the laminate comprises a closure flap configured to adhesively couple opposite sides of the laminate so that the laminate forms a substantially cylindrical shape with at least a portion of the tubular core enclosed therein; and a charge dissipator applied to the polymeric film sheet layer in an amount sufficient to reduce a static charge on the exterior surface of the laminate without affecting the closure flap's ability to adhesively couple the opposite ends of the laminate, wherein the charge dissipator provides increased resistance to shipping damage during transportation of the pipe insulation product.
