Core Characteristics of Aluminum Foil Mylar Tape
Material Composition:
Composed of a thin aluminum foil layer (typically 4–9 µm) laminated to a polyester (PET) film for durability and flexibility
Some variants include a conductive adhesive layer for enhanced EMI shielding .
Key Properties:
Electromagnetic Shielding (EMI/RFI): Blocks interference in electronics (e.g., laptops, smartphones) with aluminum purity ≥99.95% .
Thermal Resistance: Withstands temperatures from -40°C to 150°C, with high-end variants (e.g., flame-retardant tapes) tolerating up to 260°C .
Chemical & Weather Resistance: Resists moisture, UV rays, and solvents, making it suitable for outdoor and industrial use .
Tensile Strength: ≥50 MPa for tear-resistant applications like cable shielding .
Adhesive Types:
Acrylic: Offers long-term adhesion and solvent resistance (common in HVAC and electronics) .
Conductive Adhesives: Used for EMI shielding in high-frequency cables (e.g., HDMI, DVI) .
