3M™ Nextel™ 440 Yarn
High-Alumina Ceramic Fiber Yarn for Extreme Heat Applications
3M™ Nextel™ 440 Yarn is a high-performance continuous filament ceramic fiber yarn
engineered for applications requiring exceptional thermal stability, mechanical strength,
and oxidation resistance at elevated temperatures.
Composed primarily of high-alumina ceramic fibers, this yarn provides
improved high-temperature strength and creep resistance compared to lower alumina materials.
With the ability to perform in temperatures approaching 1300°C, Nextel 440 yarn
is ideal for aerospace insulation, industrial thermal protection systems, and advanced
high-temperature textile applications.
