Manufactured from continuous filament alumina fibers
Boron free, these fibers are for the most demanding applications for extremely high temperatures up to 2300°F. Alumina thread is coated with PTFE to provide good lubrication during the sewing process. This product is excellent to use when no other sewing thread can withstand service temperatures. At 2300°F/1300°C there is little or no shrinkage of the thread.
