Aluminum Foil Fiberglass Cloth Tape

• Tape Description

  Engineered using an advanced composite lamination process, this specialized aluminum foil tape features a robust multi-layer backing (7µm aluminum foil / flame-retardant adhesive / 110gsm 12×12 fiberglass cloth) protected by an easy-release silicone liner. The outer aluminum surface provides high light and radiant heat reflectivity with excellent flexibility, while the integrated glass fiber cloth supplies superior vertical and horizontal tensile strength to prevent tearing under mechanical stress.

  Beyond thermal insulation and duct sealing in HVAC and industrial systems, this tape serves as a type-approved safety barrier designed to prevent flammable hot oil sprays from contacting high-temperature surfaces in engine rooms and industrial machinery. Its airtight and watertight sealing capabilities create a permanent vapor barrier, protecting underlying equipment from heat, moisture, chemicals, and abrasion.

• Features & Benefits

  • High-Temperature & Radiant Heat Reflection: The reflective aluminum foil layer repels radiant heat and withstands high operating temperatures, safeguarding sensitive components.
  • Reinforced Tensile Strength: The embedded fiberglass cloth grid delivers exceptional tear resistance and structural strength under mechanical tension.
  • Airtight & Watertight Vapor Barrier: Creates an impermeable seal against moisture transmission, hot air, and water ingress.
  • Flame-Retardant Safety Construction: Formulated with FR adhesives to meet strict safety standards, making it ideal for engine room spray protection and thermal jacketing.
  • Solvent-Acrylic Adhesion: High-performance adhesive bonds reliably to metal, insulation jacketing, and smooth or irregular industrial surfaces.

• Applications

  • High-Temperature Sealing: Sealing and joining thermal insulation materials across furnaces, ovens, kilns, and high-temperature ductwork.
  • Engine Room & Safety Shielding: Wrapping fuel lines and hot surfaces to protect against flammable hot oil spray in marine and industrial engine compartments.
  • HVAC & Industrial Ducting: Sealing high-temperature air ducts, exhaust pipes, and thermal distribution systems to prevent thermal loss.
  • Aerospace & Automotive Heat Shields: Protecting sensitive electrical wiring, hoses, and mechanical parts from radiant exhaust and engine heat.
  • Industrial Pipe Wrapping: Wrapping and insulating high-pressure steam pipes, boilers, and industrial equipment exposed to harsh environments.

FAQ:

Q1. What is the layer construction of Fiberglass Aluminum Foil Tape?
A: The tape features a composite backing made of 7µm aluminum foil, flame-retardant glue, and a 110gsm 12×12 glass cloth weave, coated with a solvent-based acrylic adhesive and backed by a silicone release liner.

Q2. How does this tape differ from standard aluminum foil tape?
A: Unlike standard foil tape, this tape is reinforced with a woven fiberglass cloth backing. This gives it significantly higher tensile strength, superior tear resistance, and enhanced durability in high-stress, high-temperature environments.

Q3. Can this tape be used for engine room fire prevention?
Yes. It is designed as a spray protective jacket to prevent flammable hot oil mists from spraying onto hot engine surfaces and causing fire hazards in marine and industrial environments.

Q4. Is Fiberglass Aluminum Foil Tape an effective vapor barrier?
A: Yes. The impermeable aluminum layer provides airtight and watertight sealing, effectively blocking moisture vapor transmission and preventing corrosion under insulation.

Q5. Does this tape require tools to apply?
A: Because of the heavy-duty fiberglass cloth reinforcement, it is recommended to cut the tape using shears or a utility knife rather than tearing it by hand to ensure clean edges and proper seating.
