EPOWOOL® ceramic fibers are manufactured from alumina-silicamaterials through blowing or wrestling process. They are available in a variety of chemistries anddiameters which can service a wide variety of applications. Inaddition, these fibers can be further modified by chopping orby removal of the shot.
EPOWOOL® fibers exhibit excellent chemical stability andresistance to attack from most corrosive agents.
General Characteristics

ETOPWOOL® Special Fiber Bulk
Besides of the standard bulk, the special fiber bulk is also available to meet different requirements in specific application. "EPOWOOL " high index fiber could be used for strengthening material for its pretty low shot content. " EPOWOOL" grinding fiber acquired shorter fiber length by grinding process and widely used in kinds of coating material.
