Multi-use, heat resistant textiles insulate and protect electrical components from extreme temperatures.
3M™ Nextel™ Ceramic Fibers and Textiles are specially designed to function in extreme environments. With a combination of low thermal conductivity and high electrical resistance, these materials are ideal for use where electrical wiring, cable trays or conduits are exposed to high temperatures.
Resilient and flexible even at temperatures up to 2372°F, Nextel ceramic fibers and textiles are designed to withstand demanding environments ranging from heaters and fuel cells to electrical systems in civilian and military aircraft. Nextel ceramic fibers and textiles are compatible with many alloys, without acids or chlorides that could leach out and cause etching of metal. Engineered to survive today’s most challenging high temperature conditions, Nextel products for electrical insulation help ensure reliable electrical transmission when the heat is on.
Nextel textiles can be processed using conventional textile technology such as weaving and braiding. They are available in a variety of configurations, including:
- Sewing thread
- Heat resistant to 2372ºF (1300ºC)
- Compatible with a variety of alloys
- Low shrinkage rate
- Electrically insulative
- Flame resistant
- Low moisture absorption
The crystalline structure and chemical formulation provide an oxide ceramic fiber with surprising flexibility, strength, and resiliency – enabling a wide range of high temperature applications. These materials are ideal for insulating thermocouples and wires in heat-intensive electrical applications.
