Brief Introduction
ROSEWOOL ceramic fiber board is made of ceramic fiber cotton by the process of vacuum forming or dry process refined by dry and machining. It has good specialties of rigid ity flexibility heavy intensity anti-wind erosion, non-expansion, lightweight, and easy to construct. It can be cut and bent optionally. Thus, it is the practical and efficient material of kiln and furnace, pipe and other thermal insulation equipment.
