Wondering how ceramic fiber blankets perform in real high-temperature applications? This video demonstrates a needled ceramic fiber blanket roll in refractory expansion joints, showing how its elastic fiber structure absorbs thermal shock during rapid heating and cooling. Watch a close-up walkthrough of compression and recovery, joint sealing against heat and gas leakage, and installation around furnace doors and seals. Learn why binder-free needling maintains integrity where glued products fail, and see the material's flexibility and fit in high-temp process lines.
