– Product Description –
Ceramic Fiber Board is a rigid, high-performance insulation product manufactured from spun ceramic fibers (primarily alumina-silica) bonded with inorganic binders and processed through a vacuum-forming or wet-laid process followed by curing. It is designed to provide exceptional thermal insulation, resistance to thermal shock, and structural stability at high temperatures.
Its rigid board form makes it superior to ceramic fiber blankets for applications requiring a self-supporting structure, good abrasion resistance, and the ability to be machined into specific shapes.
