Product Benefits

Multilayer shielding-oriented construction

The aluminum–PET composite provides a defined multilayer structure, while the graphene coating is included as a functional surface layer in the supplied specification.

Flexible width conversion

The stated finished-width range from 3 mm to 500 mm supports different cable and electronic assembly requirements, subject to material and production confirmation.

Typical Applications

Coaxial cables.
Local area network cables.
Electronic communication wires.
Computer peripheral cables.
Other electronic products requiring interference-shielding materials.

Storage and Handling

Store unopened material at room temperature below 23°C ± 2°C and relative humidity of 50 ± 10%.
The supplied specification states a safe storage period of six months for unopened material under the stated conditions.
Handle carefully; do not roll the product on the floor.
