Contact Us |
High Temp Tapes Company is an aluminum foil fiberglass cloth tape manufacturer for industrial heat reflection, pipe wrapping, thermal shield layers, and equipment insulation work. The tape combines woven fiberglass cloth backing with a reflective aluminum foil lamination, giving it better tear strength, puncture resistance, and wrapping support than thin foil-only tape. It is made for insulation surfaces, heated metal housings, and curved pipe sections where heat reflection and mechanical protection are both needed.

Benefits
- Reflective aluminum foil lamination helps reduce radiant heat impact on pipe and equipment surfaces.
- Fiberglass cloth backing improves fabric tear strength, puncture resistance, and dimensional stability.
- Better mechanical support than thin foil-only tape on curved, rough, or frequently handled surfaces.
- Suitable as a heat reflective pipe wrapping tape where overlap strength and surface contact are important.
- Solvent acrylic adhesive is suitable for standard insulation work, while silicone adhesive can be selected for higher-temperature requirements.
- Clean slitting edge control helps reduce loose fiberglass yarns during roll conversion and on-site wrapping.
- Sample wrapping observation can check foil lift, edge fray, adhesive transfer, and fiber shedding before bulk use.
- Stable roll tension helps the tape unwind more smoothly during hand wrapping, die-cutting, and narrow-width slitting.
Applications
- Pipe wrapping for hot water pipes, steam lines, and insulated metal pipe sections
- Thermal shield layers around equipment housings and machinery protection areas
- Equipment insulation seams that need reflective surface protection and cloth strength
- Heat reflective wrapping over insulation blankets, jackets, and removable covers
- Industrial insulation systems where the tape must resist tearing during installation
- Curved and uneven metal surfaces where dimensional stability is important
- Narrow-width converted rolls for fabrication, insulation assembly, and maintenance work
- Protective wrapping where radiant heat reflection and fabric-supported strength are both required
Product Overview
Aluminum foil fiberglass cloth tape is made for insulation work where a reflective foil surface alone is not strong enough. The aluminum foil lamination helps reflect radiant heat from pipes, equipment covers, insulation jackets, and heated metal surfaces. Under the foil, the fiberglass cloth backing gives the tape fabric-supported strength, so it can handle wrapping, pressing, overlap bonding, and narrow-width slitting with better stability.
The main difference from ordinary foil-only tape is the woven glass cloth layer. This glass cloth reinforced foil tape helps reduce foil splitting when the roll is pressed around curved surfaces or converted into smaller widths. It also gives the tape better resistance against puncture, rubbing, and edge tearing during installation.
In typical factory sample checks, a 170 um class tape may show peel adhesion around 16-20 N/25 mm and tensile strength around 250-270 N/25 mm. Actual results depend on foil thickness, glass cloth weight, adhesive grade, surface condition, and test method. Before bulk slitting, sample rolls are usually checked for foil lift, edge condition, wrapping fit, fiber shedding, and adhesive transfer after repeated unwinding.
How Does Fiberglass Cloth Backing Improve Heat Shield and Mechanical Protection?
Fiberglass cloth backing works as the strength layer of the tape. When the tape is wrapped around pipes, insulation blankets, equipment covers, or heated metal parts, the woven fabric helps resist tearing, puncture, rubbing, and shape distortion. The aluminum foil lamination faces the heat source and supports heat reflection, while the cloth backing keeps the tape stable under handling pressure. This makes it suitable as a thermal shield insulation tape in areas where a reflective surface also needs fabric-supported strength.
What Should Be Checked to Reduce Edge Fray During Slitting and Wrapping?
For aluminum foil fiberglass cloth tape, edge quality should be checked before large roll conversion or repeated pipe wrapping work. The fiberglass cloth backing gives the tape its fabric tear strength, but a poorly slit edge may release loose yarns during unwinding, overlapping, or hand pressing around curved metal surfaces. Clean blade condition, roll tension, backing weave density, and adhesive anchoring all affect slitting edge fray control. During sample confirmation, the tape can be unwound, cut, wrapped around a test pipe, and rubbed lightly along the edge to observe fiber shedding. This helps confirm whether the foil lamination stays stable and whether the cloth edge remains neat during thermal shield or equipment insulation use.
FAQ
Is this tape suitable for high-temperature pipe wrapping?
Yes. It is suitable for industrial pipe wrapping where heat reflection, cloth strength, and surface protection are needed. The exact temperature range should be confirmed by adhesive grade and sample testing.
What makes this tape stronger than ordinary foil-only tape?
The woven fiberglass cloth backing improves tensile strength, puncture resistance, and tear resistance. It helps support the aluminum foil lamination during wrapping, pressing, cutting, and overlap bonding.
Can the tape be custom slit for narrow insulation work?
Yes. High Temp Tapes Company can provide custom slitting widths depending on roll format, edge requirement, and application method. A slitting edge check is recommended before bulk production.
What should be tested before bulk use?
A sample should be checked for peel adhesion, foil lift, edge fray, fiber shedding, wrapping fit, and peel after heat exposure. These observations help match the tape to real insulation conditions.
