Aluminum foil tape is an industrial tape made of rolled aluminum foil as the base material and coated with high-performance pressure-sensitive adhesive. Its core properties include high-temperature resistance, UV resistance, strong sealing, and conductive heat insulation, making it an essential material in HVAC (heating, ventilation, and air conditioning), electronic manufacturing, building waterproofing, and other fields.
Core uses and industry applications of aluminum foil tape
Heating, ventilation, and air conditioning (HVAC)
Used for sealing duct joints to prevent air and heat leakage
Repair the insulation layer of air conditioning pipes to improve energy efficiency
Building waterproof engineering
Roof crack repair, waterproof roll overlap sealing
Basement moisture barrier reinforcement (such as aluminum foil tape + insulation cotton)
Electronic and electrical manufacturing
Electromagnetic shielding (EMI/RFI protection)
Insulation packaging of transformers and lithium batteries
Automotive industry
Fixing the exhaust pipe insulation layer
Wire harness protection and sealing
Solar engineering
Photovoltaic panel backplane joint sealing, weather resistance, and anti-aging
Key parameters for purchasing aluminum foil tape

General range: 0.03 mm~0.1 mm, the thicker, the higher the mechanical strength
Adhesive type
Acrylic glue: high temperature resistant (up to 150℃+), environmentally friendly, and odorless
Rubber-based glue: strong initial adhesion and low cost
Back adhesive adhesion
Industry standard: ≥10 N/cm (actual measured value affects the durability of the seal)
Fire rating
UL certification (such as UL 723): flame retardant grade (Class A), First choice for high-end projects
Heat resistance
Ordinary type: -20℃~80℃
High temperature type: -40℃~200℃
Industry trend: Environmental protection and high performance become the mainstream
Solvent-free adhesive: Complies with EU REACH regulations
Composite structure: Aluminum foil + fiberglass cloth to enhance tear resistance
