Coaxial cable with strippable center conductor precoat

A coaxial cable comprising:

• an inner conductor;
• a closed cell foam polyolefin dielectric layer surrounding said inner conductor;
• an outer conductor surrounding said dielectric layer and bonded to the dielectric layer;
• and a precoat layer disposed between said inner conductor and said dielectric layer, said precoat layer comprising a thermoplastic polymer composition comprising a blend of low density polyethylene having a melt index of at least 35 g/10 min. and ethylene acrylic acid copolymer, and said precoat layer forming a first bond interface with the inner conductor and a second bond interface with the dielectric layer, wherein the ratio of the axial shear adhesion force of the first bond to the axial shear adhesive force of the second bond is less than 1, and wherein the ratio of the rotational shear adhesion force of the first bond to the rotational shear force of the second bond is less than 1.

A coaxial cable comprising:

• an inner conductor, a dielectric layer surrounding said inner conductor;
• an outer conductor surrounding said dielectric layer;
• and a precoat layer disposed between said inner conductor and said dielectric layer;
• wherein the precoat comprises a blend of low density polyethylene and ethylene acrylic acid copolymer, and wherein the low density polyethylene has a melt index of at least 50 g/10 minutes, said precoat layer forming a first bond interface with the inner conductor and a second bond interface with the dielectric layer, the precoat layer being of sufficient thickness and continuity as to block axial migration of moisture along the inner conductor, and wherein the strength of said first and second interfaces is such that the precoat layer is removed completely and cleanly from the inner conductor as a result of the shear force applied to the precoat layer during preparation of the cable end for receiving a connector using a standard commercially available coaxial cable coring tool.
