Nextel™ BF-30 Fabric

High-Performance Ceramic Fiber Fabric for Extreme Temperature Applications

3M™ Nextel™ 440 Woven Fabrics BF-30 are high-performance ceramic fiber textiles engineered for demanding high-temperature environments where excellent thermal stability, oxidation resistance, and mechanical strength are required.

Manufactured under the advanced Nextel ceramic fiber product family, BF-30 woven fabrics are widely used in aerospace thermal protection systems, industrial furnace insulation, and high-temperature composite reinforcement applications.

These fabrics are woven from Nextel 440 continuous filament yarn composed of alumina-boria-silica ceramic fibers with higher alumina content, providing enhanced creep resistance, superior mechanical strength, and excellent oxidation stability at elevated temperatures.

Product Overview

Nextel 440 BF-30 woven fabrics are designed for reliable performance in extreme heat and oxidizing environments. The woven ceramic textile structure offers flexibility, dimensional stability, and durability, making them suitable for thermal insulation systems, structural components, and advanced composite reinforcements.

Compared with traditional fiberglass or silica fabrics, these fabrics provide higher temperature capability, improved creep resistance, and better strength retention, making them ideal for critical aerospace and industrial thermal protection applications.
