AL51 is a high-performance, general-purpose aluminum foil tape constructed with 2.0 mil dead-soft aluminum designed for excellent conformability and durable sealing performance. The aggressive high-shear acrylic adhesive provides strong, long-lasting adhesion while maintaining reliable moisture and vapor barrier protection.

This construction delivers excellent heat and light reflectivity, making it well suited for thermal management and surface protection applications. The dead-soft aluminum allows the tape to conform smoothly to surfaces, providing a clean, uniform finish while maintaining seal integrity.

Commonly used for HVAC duct sealing, protective masking during chemical or processing operations, and general industrial sealing, AL51 provides dependable performance across a wide range of temperature environments.

Format Applications

Strip Format: Ideal for continuous seams, duct joints, insulation runs, and long-span sealing
Dot Format: Designed for precision applications including screw coverage, puncture repair, and localized masking

Primary industries include HVAC, industrial manufacturing, marine, aerospace, and appliance sectors.
