Material Notes:
Quartzel® fiber is produced from quartz crystal that is ground, purified, fiberized by a fusion process. It is homogeneous, non-porous, continuous, amorphous, ultra pure silica glass. It is available in the form of yarn, roving, chopped strands, wool, and felts.It is used in dielectric applications (radomes, circuit boards), thermal applications (high temp insulation for aerospace, asbestos replacement, furnace linings, hot gas filtration), and reinforcement for composites (with resins such as phenolics or epoxies).
