Nextel™ Chopped Fibers

Made from 3M™ Nextel™ Fibers, these chopped fibers are used in composite applications. The fibers, commonly chopped to 1/8", 1/4" and 1/2" lengths, are widely known for their role in ceramic underbody tiles which protect NASA's Space Shuttles.

NOTE: These fibers are considered non-respirable. Fibers with diameters greater than 3 microns are considered nonrespirable in humans. 3M™ Nextel™ 312, 440, 550, 610 and 720 Ceramic fibers are 7-13 microns in diameter and therefore pose no known chronic health effects.
