The thickness of aluminum foil waterproof tape typically ranges from 0.05 mm to 0.15 mm, with 0.08 mm being a common specification. The thickness is determined by both the aluminum foil substrate and the adhesive layer: the aluminum foil thickness is approximately 0.03-0.07 mm, and the adhesive layer thickness is approximately 0.02-0.08 mm.
Thicker tapes (e.g., 0.1 mm and above) offer better waterproof sealing and durability, suitable for outdoor or rough surfaces; thinner tapes are more flexible and easier to apply to complex shapes. The choice of thickness should consider the application scenario: 0.1 mm and above can be used for roof joints; 0.06-0.08 mm is suitable for pipe wrapping. Thickness affects roll length and application feel; thicker is not always better, a balance between adhesion and flexibility is necessary.
International standards specify thickness tolerances, and high-quality products have uniform thickness. Consumers can check the thickness by observing the cross-section or referring to technical parameters to ensure it meets project requirements.
