30 Micron Aluminum Foil Tape for HVAC Duct Sealing and Moisture Barrier Applications
Product Overview
30 Micron Aluminum Foil Tape is manufactured with a high-tensile aluminum foil backing and premium solvent acrylic adhesive. Designed for HVAC, insulation and construction applications, it provides a durable moisture barrier, strong sealing performance and long-term resistance to heat, humidity and environmental exposure.
Key Features
Excellent Moisture and Vapor Barrier Performance: The aluminum foil backing creates an effective barrier against moisture penetration and vapor transmission, helping protect insulation systems and HVAC installations from condensation damage.
Strong Permanent Bonding: The solvent acrylic adhesive provides high initial tack and long-term holding power for reliable sealing of duct joints, seams and insulation facings.
High Reflectivity: Aluminum foil reflects heat and light efficiently, contributing to improved thermal insulation performance and energy efficiency.
Weather and Aging Resistance: Suitable for both indoor and outdoor environments, offering resistance to UV exposure, temperature fluctuations and environmental aging.
Wide Operating Temperature Range: Maintains performance across temperatures from -30°C to +120°C, making it suitable for both hot and cold climate applications.
