Detailed description
Pure Aluminum Foil Tape is made from pure aluminum foil, coated on one side with a high-performance pressure-sensitive adhesive and then laminated with a release paper (or film). Its core is the soft aluminum foil. For applications requiring only sealing and insulation, and in relatively mild environments, aluminum foil tape offers the most cost-effective option. Key applications include HVAC equipment, refrigerators and refrigeration equipment, electronics, and kitchen hoods.

It cleverly combines the excellent properties of aluminum foil (such as heat reflection, thermal conductivity, moisture sealing, and weather resistance) with the strong adhesive properties of the adhesive, making it a key material for sealing, shielding, thermal conductivity, and protection in a wide range of applications, including heating, ventilation, and air conditioning (HVAC), refrigeration, electronics, and construction.
Aluminum foil fiberglass cloth tape, sometimes simply referred to as “aluminum foil fiberglass cloth tape,” is a high-performance reinforced aluminum foil tape.
It is not made from a single layer of aluminum foil, but rather a composite tape. Its structure consists of an aluminum foil outer layer laminated with fiberglass cloth through a unique lamination process, and then coated with a high-performance pressure-sensitive adhesive. This construction is designed to perfectly combine the advantages of both materials: retaining the excellent heat-reflecting, sealing, and moisture-proof properties of aluminum foil while leveraging the unparalleled mechanical strength and durability of fiberglass cloth. As a result, it is considered a “heavy-duty upgrade” to standard aluminum foil tape, specifically designed for use in demanding industrial environments that require even greater strength, abrasion resistance, and durability.
1. Heat Reflection & Insulation:
Aluminum foil’s surface reflects a significant portion of radiant heat, making it an excellent thermal and insulation material.
2. Sealing & Moisture Barrier:
Aluminum foil itself is completely impermeable to water and air, so the tape forms a perfect seal, effectively blocking moisture and water vapor.
3. Thermal & Electrical Conductivity:
Thermal conductivity enables it to conduct heat quickly and evenly, often used to improve cooling and heating efficiency.
Thermal conductivity makes it suitable for electromagnetic shielding (EMI) and electrostatic discharge (ESD) grounding.
4. Weather Resistance & Durability:
Aluminum foil offers excellent corrosion and aging resistance, resisting UV rays and extreme weather conditions, making it ideal for long-term outdoor use. 5. Strong Adhesion:
Utilizes high-performance pressure-sensitive adhesive to ensure a strong, long-lasting bond across a wide temperature range.
1. Backing Material
The backing is the main body of the tape, providing its core metallic properties.
Soft Temper Aluminum Foil:
Composition: This is the base material for all aluminum foil tapes. High-purity soft-temper aluminum foil is typically used.
Properties: “Soft” means the foil is extremely flexible, offering excellent ductility and conformability, allowing it to easily wrap around irregular surfaces and pipes, ensuring a tight, seamless fit.
2. Reinforcement Material: To enhance the mechanical strength of the tape, a layer of reinforcement is added between the aluminum foil and the adhesive layer.
Fiberglass Scrim:
Composition: A grid-like structure formed by interlaced fiberglass yarns. Function: This greatly increases the tape’s tensile strength, preventing it from breaking easily under extreme tension. This is the core of “reinforced aluminum foil tape.”
Fiberglass Cloth:
Composition: A cloth made of tightly woven glass fiber filaments.
Function: This provides not only extremely high tensile strength but also exceptional tear and puncture resistance. This is the core of “aluminum foil fiberglass cloth tape” and the strongest type.
3. Adhesive
The adhesive is crucial to determining the tape’s bonding performance, temperature resistance, and durability.
Acrylic Adhesive:
Features: This is the most popular and versatile adhesive type. It offers:
High Bond Strength: It forms a strong, permanent bond on a variety of surfaces.
Wide Temperature Range: It maintains stable performance over a wide temperature range (e.g., -30°C to +120°C). Excellent Weathering Resistance: Excellent UV and aging resistance, making it ideal for long-term outdoor use.
Classification: Available in solvent-based and emulsion-based types, solvent-based acrylic adhesives generally offer superior overall performance.
Rubber Adhesive:
Features: Its primary advantage is very high initial tack, but its temperature and weather resistance are inferior to acrylic adhesives.
Applications: Used in indoor applications where high initial tack is required but long-term weathering resistance is less critical.
Conductive Adhesive:
Features: Conductive particles (such as nickel, copper, or carbon powder) are added to acrylic adhesives, making the adhesive inherently conductive.
Applications: Specially designed for use in the electronics industry where electromagnetic shielding (EMI) and electrostatic discharge (ESD) shielding are required, ensuring a complete conductive path between the adhesive tape and the adhered object.
4. Release Liner
Composition: Typically silicone-coated glassine paper or PET film.
Purpose: Protects the adhesive surface from contamination during storage and transportation, and facilitates precision die-cutting.

Specific Applications:
Securely attaching the evaporator and refrigeration piping (usually copper tubing) to the refrigerator’s interior or back panel. 3. Electronics Industry
In precision electronic products, aluminum foil tape (especially conductive aluminum foil tape) is a key material for resolving electromagnetic interference (EMI) issues.
Specific Applications:
Wrapping cable harnesses to prevent internal signal leakage or interference from external signals.
Applied to the inside of electronic device housings to form a ground shield.
Used to dissipate static electricity and provide an electrostatic discharge (ESD) path.
4. Building Repair and Outdoor Applications
Aluminum foil tape’s excellent weather resistance and water resistance make it a reliable “all-weather” repair material.
Specific Applications:
Used for temporary repairs and sealing cracks and seams in metal roofs, color-coated steel sheets, and gutters.
Used for wrapping and protecting pipes exposed to the outdoors to protect them from UV rays and environmental corrosion.
Function:
Waterproof and weather-resistant: Strong adhesion and a corrosion-resistant aluminum foil base provide a durable, reliable waterproof seal that effectively withstands wind, rain, and sunlight.
5. Automotive and Aerospace
Specific Applications:
Used for wrapping wiring harnesses, fuel lines, and sensitive components within the engine compartments of automobiles and aircraft. Function:
Thermal Insulation: Reflects the significant radiant heat generated by the engine and exhaust system, protecting wiring harnesses and components from high-temperature damage.
