First developed for use in manufacturing the tile sheathing for the U.S. Space Shuttle, Q-Fiber® has extremely high thermal capabilities combined with ultra-light weight. The pure silica fiber is exceptionally pure and extremely stable, with no thermal expansion, contraction, or distortion. Uses Due to its high degree of stability and pure, fibrous silica material, Q-Fiber is well-suited to applications requiring a fiber that does not degrade under extreme conditions or applications requiring high-performance filtration. As a lightweight temperature-resistant insulation material, Q-Fiber is perfect for a variety of aircraft and automotive uses. Q-Fiber is used for environmental test filters used in a variety of analytical applications. Advantages Low density, non-crystalline Q-Fiber features superior characteristics including: Pure silica fiber for the highest degree of thermal resistance and stability. No degradation in extreme usage conditions, making it an ideal filter for highly accurate testing results. Extremely lightweight for applications requiring a minimum of weight and maximum thermal protection. Furnished in bulk form and felt form for specialty applications.
