What Is Ceramic Tape?
Ceramic tape is a type of tape created from spun yarn, comprising ceramic fibers blended with a small proportion of organic fibers and reinforced with glass fibers. Ceramic, encompassing all manmade materials other than metal, wood, and plastic, is crafted by combining rocks, clay, and other minerals, followed by molding and baking. This tape offers greater heat resistance than fiberglass and is commonly employed as a heat insulator in high-temperature environments, such as in boiler and pipe insulation.
Uses of Ceramic Tapes
Due to its remarkable heat resistance, ceramic tape finds its application in areas with high temperatures, including use in shut-off curtains, pipe insulation, and combustion work. It is specifically utilized for lagging boilers and pipes, insulating piping and exhaust ducts, furnace curtains, heat treatment slow cooling covers, welding spark prevention, and heat-resistant packing. Ceramic tape is also employed for filling brick expansion allowances, sealing furnace doors, covering heat-resistant water hoses, muffler insulation in internal combustion engines, blocking radiant heat, and burn prevention.
Characteristics of Ceramic Tapes
Composed of spun yarn with ceramic and organic fibers, and reinforced with glass fibers, ceramic tape exhibits outstanding heat resistance and flexibility. It serves as an asbestos alternative, being ideal for heat, sound, and cold insulation, particularly in high-temperature settings. Relative to silica cloth and alumina tapes, it is more cost-effective.
Amorphous ceramic fiber (refractory ceramic fiber/ RCF) is regulated under RCF regulations, necessitating specific measures like usage notification, working environment assessments, special control substance measures, chief worker appointments, and special health checkups. However, products not using RCF, and thus not subject to these regulations, are available. These non-RCF products use bio-soluble fiber (BSF) as the primary material, with glass fiber, SUS wire, Inconel wire, and organic fibers like rayon as reinforcement, instead of RCF.
