Blue Aluminum Foil Mylar Film Roll, commonly known as AL+PET Laminated Film, is a composite material widely used in cable manufacturing, especially for shielding and insulation.
Blue Aluminum Foil Mylar Film AL+PET Laminated Film consists of a two-layer structure:
Aluminum: The thin aluminum foil gives the film the ability to shield electromagnetic interference (EMI) and radio frequency interference (RFI).
Polyester: Polyester film is an insulating material with high tensile strength, durability and resistance to temperature changes. PET ensures that the foil maintains its integrity during handling and installation, providing the necessary structural support for the aluminum layer.
Blue Aluminum Mylar Film is produced by tightly laminating PET and aluminum layers to form a bonded material. After lamination, the film is rolled into rolls, usually in widths suitable for various cable manufacturing processes. These rolls are then ready for the production of shielded cables.
Key Features and Benefits
EMI Shielding: Aluminum provides highly effective EMI shielding, such as in data cables and power cables.
Durability and Strength: PET ensures the durability of the film, providing tensile strength to prevent tearing or deformation during manufacturing or installation. The material is resistant to wear and tear, which can extend the service life of the cable.
Flexibility: Despite its strength and durability, the laminated film remains highly flexible, making it suitable for applications where the cable needs to be bent or flexed without compromising shielding performance.
Moisture and Chemical Resistance: The polyester layer has excellent resistance to moisture, oils, and solvents, providing additional protection for cables exposed to harsh environmental conditions.
High Temperature Resistance: The material is stable over a wide temperature range, typically -40°C to +150°C, depending on the thickness of the layer, which ensures that the cable will function properly even in extreme conditions.
UV Protection: The blue color of the Mylar film not only gives the cable a unique look but also provides additional protection against ultraviolet (UV) radiation, reducing the risk of degradation caused by prolonged exposure to sunlight.
