FIBERMAX VACUUM FORMED SHAPES

Home > Products > Alkaline Earth Silicate Wool, Polycrystalline Wool > FIBERMAX VACUUM FORMED SHAPES

VACUUM FORMED SHAPES are produced by dewatering a slurry of BULK FIBER and high-temperature binders. This manufacturing method permits considerable freedom to vary shape and thickness.
Please do not hesitate to contact us if you are concerned about smoke or smell during the initial heat-up.
