COPOLYMER COATED ALUMINUM TAPE

The Star Materials Copolymer Coated Aluminum Tape (CCAT) is used inside of underground power/telecommunication cables. Its main purpose is to ensure stability and continuity of flawless power and telecommunication. Additionally, the CCAT function is to avoid interference, moisture penetration and corrosion but also to avoid separation of inner cable sections or groups.

This tape consists of an aluminum tape on one side and an adherent ethylene copolymer coating on the other side, is available either as natural or in blue color.

The Copolymer shows excellent adhesion to the aluminum substrate. It bonds to low density polyethylene (PE), linear low-density PE, medium density PE and high-density PE. The aluminum is of a great purity and quality, and has high conductivity characteristics.

We offer this tape either single sided or double sided. Please check below table for thicknesses.
