Aluminum Foil Fiberglass Heat Tape

Aluminum Foil Fiberglass Heat Tape Material: Aluminum foil with fiberglass backing Color: Silver reflective surface Adhesive: High temperature silicone adhesive Thickness: Common range 0.16-0.22 mm Width: Standard and custom slit widths available Use: Hot pipe wrapping and heat shielding Contact Us

Insulative Tape Company is a manufacturer of aluminum foil fiberglass heat tape for hot pipe wrapping, equipment insulation, heat shielding, and short-term high temperature exposure around industrial heat sources. The reflective aluminum surface should face the heat source to help reduce radiant heat, while the fabric reinforced backing gives the tape better resistance against puncture, tearing, and movement on curved surfaces. With a typical thickness of 0.16-0.22 mm, it is made for areas where a flexible heat protection tape is easier to apply than a rigid shield or heavy insulation cover.

Benefits

• Reflective aluminum surface helps reduce radiant heat exposure around nearby components.
• Fabric reinforced backing improves puncture and tear resistance, with typical tensile strength around 180-260 N/25 mm.
• High temperature silicone adhesive performs better through heat cycling than general-purpose adhesive.
• Flexible construction wraps more easily around pipe bends, hose routes, valve edges, and uneven surfaces.
• Helps protect insulation seams from abrasion, edge lifting, and light mechanical contact.
• Suitable for small heat-risk areas where rigid shields or thick blankets are difficult to fit.

Applications

1. Hot pipe wrapping tape for steam lines, heated ducts, exhaust-adjacent pipes, and exposed insulation edges.
2. Equipment insulation heat tape for panels, valve covers, pump surroundings, access doors, and heated metal surfaces.
3. Heat shielding near hoses, lines, guards, brackets, and parts exposed to intermittent radiant heat.
4. Welding protection around fixture edges, bench surfaces, and nearby covers exposed to sparks.
5. Thermal spray protection around selected workpiece borders, repair areas, and temporary shielding surfaces.
6. Maintenance repair where fabric reinforced heat shielding tape is needed for a small exposed area.

Where Can Aluminum Foil Fiberglass Heat Tape Be Used Around Hot Equipment?

Aluminum foil fiberglass heat tape is useful around hot pipe sections, valve edges, equipment panels, maintenance access areas, heated ducts, hose routes, and metal surfaces close to radiant heat. For pipe wrapping, a 25%-50% overlap is commonly used to improve edge coverage, especially around bends and insulation joints where the tape is more likely to open after repeated heating and cooling. The aluminum side should face the heat source, and the tape should be pressed firmly onto a clean, dry, oil-free surface to reduce edge lifting during thermal cycling.

Product Overview

This heat-resistant aluminum fiberglass tape is used where heat protection needs to follow the shape of the part, not just cover a flat surface. It works well around hot pipes, equipment edges, heated panels, hose routes, and nearby work areas exposed to radiant heat. It is not ordinary duct sealing tape, FSK facing tape, or general masking tape. The aluminum facing, commonly 25-50 um, helps reflect heat away from the protected area, while the fiberglass backing keeps the tape stable around bends, corners, access covers, valve areas, and uneven metal surfaces.

For hot pipe wrapping, the tape can be applied over existing insulation, around exposed pipe bends, or along insulation seams that need extra surface protection. On equipment, it is often used around pump surroundings, heated duct sections, metal guards, maintenance covers, and hot surface edges. Continuous service temperature, direct contact temperature, and short-term peak exposure should be reviewed separately. A tape rated for -50C to 260C continuous service may still require testing when the surface is exposed to 300C-500C short peak heat, because the adhesive layer is usually the part most affected by long heat cycles.

Technical Data Sheet

How Does Heat-Resistant Aluminum Fiberglass Tape Help During Welding or Spray Work?

During welding, flame spray, thermal spray, or nearby repair work, nearby surfaces may face sparks, radiant heat, overspray heat, and short-term high temperature exposure. Heat-resistant aluminum fiberglass tape helps protect fixture edges, workpiece borders, equipment covers, and adjacent metal surfaces by combining thermal reflection with a fabric reinforced backing. The fiberglass layer supports the tape against tearing, puncture, and uneven contact points. After heat exposure, sample areas are usually checked for edge lift, backing fracture, and adhesive residue. It is not a replacement for a full welding blanket, but it is useful for edge protection, temporary shielding, and controlled heat protection around smaller work areas.

FAQ

Can this tape be used directly on hot pipes?

Yes, it can be used for hot pipe wrapping, but the pipe surface temperature, contact time, and adhesive grade should be checked before production use. A small test area is recommended when the surface is close to the upper temperature range.

Which side should face the heat source?

The reflective aluminum side should face the heat source when the goal is radiant heat reflection or heat shielding.

Is it suitable for long-term high temperature exposure?

It can handle continuous heat within the recommended range, but short peak exposure and long direct contact are different working conditions. The adhesive, overlap area, and surface cleanliness should be reviewed together.

What should be checked before application?

Check surface cleanliness, operating temperature, overlap width, edge pressure, vibration, and possible contact with oil, moisture, or abrasion. Peel adhesion of 5-8 N/25 mm is a useful reference, but final performance depends on the actual surface and heat cycle.
