Filtration Systems

Q-Fiber®

Description
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.
