High Temperature Textiles

TaoFibre® textile family includes ceramic fiber ropes, braids, cloth, tapes, and sleeving. TaoFibre® ceramic fiber textiles are made from alumina-silica ceramic fiber, free of asbestos. These ceramic fiber textile materials can be used in different industrial applications under temperatures up to 2300 °F (1260 °C) and have excellent chemical stability and strong resistance to thermal shock and corrosion attack. Exceptions are hydrofluoric and phosphoric acids and concentrated alkalis. TaoFibre® ceramic fiber textiles also resist oxidation and reduction. If wet by water or steam, thermal properties are completely restored upon drying. No water of hydration is present.

TaoFibre® textiles contain 15% organic carriers, which helps to establish physical formation of products. The carriers burn out at about 750 °F (400 °C). TaoFibre® ceramic fiber textiles also contain reinforcement insert materials of either inconel wire or continuous fiberglass filament to increase handling strength during installation and enhance fiber durability to rated temperatures of 2000 °F (1093 °C) for inconel wire and 1200 °F (649 °C) for fiberglass filament.

Mineral Wool Board (TB-19)

Mineral wool insulation products come in myriad forms, shapes, and sizes, including board; batt; loose fill; spray-applied; and pipe insulation. Whatever its form, mineral wool insulation resists mold, fungi, and bacteria growth because the material is inorganic. Products also offer enhanced protection against damaging moisture infiltration that can rob insulation of R-value. Further, mineral wool insulation is not corrosive and contains no chemicals that can degrade pipes and wires.

Mineral board materials applications: curtain walls, commercial roofs, basement walls, floors over unheated or open spaces (e.g., garages or porches), and other building envelope applications. Board insulation is extensively employed in industrial processes. Further, the greater density of mineral wool insulation allows the materials to achieve higher R-values and, thus, insulating power. This translates into increased year-round comfort and significant energy savings.

In partitions, floors, and ceilings, the fibrous structure and high density of mineral wool insulation offer sound absorption properties, making these products an excellent part of overall wall systems designed to reduce sound transmission.


Industrial Grade Fiberglass, Silicone-coated Fiberglass, Silica, and Ceramic Tape products. Each provides unique physical characteristics and sealing performance. Common applications for high temperature tapes include compression seals and thermal insulation wraps to contain heat and protect hoses, cables, workers, and surrounding components from heat. Even at elevated temperatures ceramic tapes are resistant to most acids and alkalis.

  • Fiberglass Tape (to 1000 °F)

    Fiberglass tapes are primarily used for selective reinforcement and wrapping applications that call for smaller coverage areas, localized strength, or even unique shapes, like tubing.
