AB Technology Group is a manufacturer and distributor of high temperature, heat & flame resistant LadderTapeä bolt-hole style gasket tape.
LadderTapeä bolt-hole style tapes are typically used as gasket seal material on access doors for ovens, furnaces and kilns, where a gasket/seal is desired on both sides of the securing fasteners such as a bolt line. LadderTapeä is also used on commercial kitchen exhaust duct flange joints as a sealing tape.
The tape purposely has warp yarns missing in the center area of the tape, with just the horizontal weft yarns holding the remaining outside sections of the tape together, giving the tape its "ladder" look and easy pass-thru over studs.
Very High Temperature and Heat Resistant Fiberglass LadderTapeä / Bolt Hole Tape
1000°F / 537°C continuous rating, high insulation value
· Very high temperature and heat resistant fiberglass sleeve and tape products are used to protect a
wide range of hoses, lines, tubes, wires and cables from high temperatures and flame. Often the
sleeve products are used in layers to provide additional protection and insulation value. Perfect
where molten metal exposure is not an issue and a lower cost alternative to silicone rubber coated
fiberglass (firesleeve). Fabric and tape is available with a PSA coating. Many items are suitable
for hot work protection during welding operations.
Many of our Fiberglass and Silica products are an excellent asbestos alternative, and can be used to replace asbestos sleeve, tape, fabric and insulation commonly used for wiring and pipe insulation.

Extreme High-Temperature and Heat Resistant InSilMax Silica and Silica XT LadderTapeä / Bolt Hole Tape
Silica protection products with 2000°F / 1093°C continuous rating
· Generally, Silica high-temperature products can be used to 2000°F / 1093°C continuously. It melts
above 3000°F / 1648°C.
· Silica sleeve; braided and texturized. Standard wall thickness is 1/16" and heavy wall is 1/8".
Product photo boarders are color coded based on the maximum continuous rating; many products
have higher short exposure ratings - but you should also consider the application when
choosing a product; such as molten splash, weld splatter, infrared shielding or abrasion resistance.
Fiberglass Products Withstand 1000°F / 537°C continuous exposure; with excursions to 1200°F / 648°C. In addition to protection, sleeve and tape can also provide an insulation value.
LadderTapeä / Bolt Hole Tape are available in the following ratings:
