  • Publication number: 20110104484
    Abstract: An underlayment material includes a sheet of masticated rubber. A vapor barrier film is extruded onto the sheet of masticated rubber. In one embodiment, a portion of the vapor barrier film extends beyond at least one edge of the sheet of masticated rubber so as to form a flap extending therefrom. An elongated adhesive strip is disposed on a first side of the vapor barrier film. The elongated adhesive strip includes a removable cover film that protects the elongated adhesive strip until the cover film has been removed. The elongated adhesive strip is positioned so as to facilitate sealing of the flap extending from the vapor barrier film of a first unit of the underlayment material to the elongated adhesive strip of a second unit of the underlayment material.

    Abstract: A fluid absorbent tape is divided into sections that can be separated to customize the length of the tape and simplify use. In one embodiment of the invention, the fluid absorbent tape includes an absorbent material enclosed in a fluid permeable cover to form an elongated fluid absorbent tape. Separating structure formed in a transverse direction through the elongated fluid absorbent tape divides the elongated tape into a first section of fluid absorbent tape and a second section of fluid absorbent tape. The first section of fluid absorbent tape is separable from the second section of fluid absorbent tape along the separating structure. In another embodiment of the invention, the fluid absorbent tape includes a fluid absorbent material including a super absorbent polymer. An elongated fluid permeable cover having a length encloses the fluid absorbent material, and is divided into sections along the length.
