Darco Southern offers a variety of Fiberglass (Tetraglas®), Silica (Tetraglas 3000®), Ceramic, Fireblanket (Silco Shield®), and Tacky Cloth (Tetraglas-T® 500) cloths. Each cloth has unique physical characteristics and protection from heat and fire. Common applications for high temperature cloths include welding blankets and curtains, fire blankets, expansion joints, insulation pad covers, gasketing products, hose covers, and a wide variety of specialty products. Even at elevated temperatures our Fiberglass, Silica and Ceramic cloths are resistant to most acids and alkalis.

Fiberglass cloth is plain woven with high-quality Type E fiberglass yarns. Fiberglass cloth will not burn and is suitable for use in applications with temperatures up to 1000°F (540°C). This cloth can be coated with vermiculite, PTFE, or graphite. Silver silicone impregnated fiberglass cloth and reflective foil coatings are available in select thicknesses and widths. Style 60 is MSHA accepted (MSHA-BC-109) for use in underground mines.
Silica cloth is woven from amorphous silica yarns and contains a minimum silicon dioxide of 96% for superior performance. Silica cloth will not burn and is suitable for use in continuous temperatures to 1800°F (980°C). Several styles and thicknesses are offered in either a satin or plain weave.
This amorphous silica cloth is also offered with a red silicone coating. With a continuous operating temperatures of 500°F (260°C), our Silfab-54 cloth can withstand a molten splash at 2200F (1200C.)
Darco Southern’s plain woven ceramic fiber cloth supports the highest continuous operating temperature at 2300°F (1260°C). Ceramic fiber cloth is manufactured from alumina-silica ceramic fiber and is asbestos free. This cloth possesses excellent chemical stability as well as strong corrosion and thermal shock resistance. Glass or Inconel inserts can be added to increase strength and durability.
Fireblanket is designed to provide protection from the hazards of high heat, sparks and flame. Fireblanket protects continuously to 500°F (260 °C) and will withstand a molten splash at 2200°F (1200°C). Made of woven fiberglass yarns in a flexible substrate, it is then coated with a high-grade silicone rubber. Fireblanket is used to provide shielding for worker life safety as well as protection of equipment, hoses and other critical components.
Resistant to hydraulic fluids, lubricating oils, and fuels, fireblanket insulates against heat loss in hoses; helps protect employees from burns; and allows shielding of cables, hoses and equipment from splashes of molten metal and heavy sparks.
Darco Southern Silco Shield® Fireblanket is available in standard sizes 40″ (1m) wide rolls and can be cut to length for custom applications. Hook & loop closure, snaps or metal turnbuckles are also available (see Silco Shield® Firesleeve with Hook & Loop Closure).
Tacky Cloth (Tetraglas-T 500 Gasket Cloth) is made from texturized fiberglass yarn which is coated and impregnated with a proprietary uncured natural rubber. It is offered with either a brass wire insert or no wire. The brass wire insert is used for added strength and density. Darco Southern’s Tetraglas-T 500 gasket cloth is suitable for applications up to 500°F (260°C). The gasket material is used where rough or uneven flanges need a sealing material. Many gaskets, tadpole tapes, and groove packings are made from this cloth for use in the boiler industry. This material can be dusted, PTFE dipped, coated in Graphite, or coated with Red and Black. Tetraglas-T 500 cloth and gaskets are meant to be cured in application. For instructions on this process, please contact Darco Southern.
