Why Choose Foil Tape?
Extreme temperature resistance
Aluminum foil tape offers exceptional performance in extreme temperatures, withstanding a range from -30°C (-22°F) to 550°C (1022°F). The aluminum layer provides excellent heat dissipation and reflectivity, achieving up to 97% thermal radiation reflectance (ASTM C1371). This makes it indispensable for HVAC duct sealing, industrial insulation, and thermal shielding in high-temperature applications.
Moisture and Vapor Barrier
The dense aluminum structure provides impermeable protection against water, vapor, and air infiltration. Tested to ASTM E96 standards, aluminum foil tape achieves a water vapor transmission rate (WVTR) of <0.02 g/m²·24h. This makes it ideal for creating airtight seals in HVAC systems, reducing energy loss, and improving system efficiency.
High Adhesion and Bonding Strength
Featuring advanced acrylic or silicone adhesives, aluminum foil tape delivers peel strengths exceeding 20 N/25mm (ASTM D3330). It adheres securely to metal, plastic, and composite surfaces, even in freezing or humid environments. Its cohesive strength ensures long-term reliability in dynamic or static applications, such as piping insulation and equipment sealing.
Structural Durability
Engineered with a tensile strength of over 450 N/50mm (ASTM D882), aluminum foil tape resists tearing, punctures, and abrasion. Its robust structure ensures durability in heavy-duty applications, such as protective wrapping for mechanical components and industrial equipment.
Chemical and UV Resistance
With excellent resistance to oils, acids, and alkaline substances, aluminum foil tape is designed for chemically aggressive environments. It maintains stability under prolonged UV exposure, making it suitable for outdoor and industrial applications such as pipeline wrapping and chemical plant maintenance.
Eco-Friendly and Sustainable
Aluminum foil tape is 100% recyclable, with a recycling energy requirement of just 5% compared to initial production. Its eco-friendly composition aligns with modern sustainability goals, making it a preferred choice for green building and manufacturing projects.
Applications Of Foil Tape
