Copolymer Coated Aluminum Tape

Copolymer Coated Aluminum Tape

The Star Materials Copolymer Coated Aluminum Tape consists of an aluminum tape coating on one side and an adherent ethylene copolymer on the other side, available either as natural color or blue. 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. This tape is mostly used for the production of telecommunication cables in order to avoid interference but also to ensure the separation of inner cable groups.
