High-temperature stability: the long-term use temperature of our polyimide fiber is up to 260℃. The fiber can be used at higher temperatures in a short time.
Dimensional stability: the dry heat shrinkage (280℃, 30min) of our polyimide fiber is less than 1%, which can guarantee the dimensional stability of filter bag.
Chemical stability: because of the unique chemical structure and dry spinning technology, our polyimide fiber has better chemical resistance compared with other high-performance fibers.
Excellent quality: mature quality control system ensures the product quality is excellent and stable.
