3M™ Nextel™ 312 Chopped Fibers

Ceramic Fiber Reinforcement for High-Temperature Insulation & Composites

3M™ Nextel™ 312 Chopped Fibers are high-performance ceramic fiber reinforcements designed for applications requiring exceptional thermal stability, oxidation resistance, and structural reinforcement in extreme temperature environments.

Made from alumina–boria–silica ceramic fibers, these chopped fibers offer excellent thermal resistance, chemical stability, and mechanical reinforcement at elevated temperatures.

With reliable performance at temperatures up to 1200°C, Nextel™ 312 chopped fibers are widely used in aerospace insulation, refractory materials, and high-temperature composite systems.

What Are Nextel™ 312 Chopped Fibers?

Nextel™ 312 chopped fibers consist of short ceramic fiber segments derived from continuous Nextel filaments. These fibers are engineered to provide uniform reinforcement and improved thermal performance in composites, insulation materials, and ceramic matrices.
