Abstract
A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing.
Claims20
A member for use in undersea applications comprising a plurality of conduits assembled into a bundle;
- the conduit being an unbonded, flexible, continuous, spoolable tube;
- the bundle being wrapped with a pressure-sensitive tape comprising:
- a backing consisting of a polymeric film;
- and
- a layer of corrosion resistant liquid crystal polymer (LCP) yarn of filaments of polyester of 2-naphthalene-6-carboxylic acid and 4-hydroxy benzoic acid oriented parallel to the length of the tape and adhered directly to the polymeric film by a first pressure sensitive adhesive;
- a second pressure sensitive adhesive coated on the first pressure sensitive adhesive and LCP filaments, the second pressure sensitive adhesive defining a functional adhesive layer of the tape, wherein the second pressure sensitive adhesive is the same as the first pressure sensitive adhesive;
- and
- wherein the tape is constructed such that it provides an initial tensile strength of at least 1000 lb/in.

A pressure sensitive tape consisting essentially of:
- a backing consisting of a polymeric film;
- a layer of corrosion resistant liquid crystal polymer (LCP) yarn of filaments of polyester of 2-naphthalene-6-carboxylic acid and 4-hydroxy benzoic acid oriented parallel to the length of the tape and adhered directly to the polymeric film by a laminating layer of a first pressure sensitive adhesive;
- and
- a second pressure sensitive adhesive coated on the first pressure sensitive adhesive and LCP filaments, the second pressure sensitive adhesive defining a functional adhesive layer of the tape, wherein the second pressure sensitive adhesive is the same as the first pressure sensitive adhesive;
- wherein the pressure sensitive adhesive further defines the functional adhesive layer of the tape, and
- wherein the tape is constructed such that it provides an initial tensile strength of at least 1000 lb/in.
