High quality FIBROX mineral fiber is converted via a unique process to a high strength paper sheet. Two versions are available: our standard FIBROX 300 PAPER and our ultra clean (< 3% shot) FIBROX 030 PAPER. They are produced in roll form in various thicknesses.

The white color, high-fiber content and temperature operating range (up to 1500°F) of FIBROX PAPER make it an excellent alternative to ceramic refractory, glass, aramid and other mineral fibers. Applications include: heat shielding; high temperature gaskets and seals; automotive and appliance thermal insulation; acoustic insulation and fire protection barriers.
