Adtech high-temperature insulation ropes are engineered to withstand extreme environments and deliver a high-quality, reliable seal in a wide range of industrial uses – from doors, oven, and tadpole seals to general caulking and stuffing applications. Our fiberglass ropes offer an economical solution for applications that reach up to 1000°F/540°C. For even greater thermal protection, ropes made from our Leached Silica and MaxSil®Tex lines provide continuous service up to 2000°F/1100°C. 

There are a number of factors that go into creating the perfect insulation rope. After all, every application requires its own set of unique performance capabilities. Off the shelf solutions don't always meet all requirements.

And that's ok. Because creating custom insulation solutions is what we do best. Our team combines an impeccable command of cutting-edge fiber technology with decades of hard-earned experience to create high-temperature ropes tailor-made for the most demanding requirements. 

Insulation Ropes

Our line of fiberglass ropes is made using E-Glass fibers, which are strong, chemically stable, electrically and thermally insulating, waterproof, and extremely resistant to high temperatures. The fibers are knitted, braided, or twisted into a durable rope and customized for required thickness and density. McAllister Mills' fiberglass ropes have a service temperature of 1000°F/540°C and can be coated with vermiculite, PTFE, and other helpful materials.

Fiberglass Dense-Knitted Round Ropes

Our dense-knitted round ropes are some of the most economical solutions for applications with service temperatures up to 1000°F/540°C. The firmer density provides superior sealing properties, and the knitted format prevents the rope from unraveling when cut. Dense-knitted fiberglass ropes resist most acids, alkalis, and solvents, and are available in varying levels of thickness (0.25" - 1.5").

Fiberglass Low-Density Round Ropes

Sometimes you may need a little more "give" in your insulation rope. Our low-density knitted round ropes are the perfect choice for such occasions, providing just the right firmness for your application. This material can be used to fabricate tadpole seals with lighter sealing pressure requirements. Like their high-density cousins, low-density knitted ropes still stand up to most acids, alkalis, and solvents and won't unravel when cut.
