Ceramic fiber paper made of silica and alumina fibers, organic and inorganic binders in order to maintain stability in temperature and chemical resistance. The particular processing of the product ensures the characteristics of the fibers to be mainteined: the paper is soft, flexible, resistant, highly insulating and with excellent resistance to chemical attacks. These products have low and controlled thickness (from 1 to 5 mm) and they are available in rolls with different heights (from 500 to 1200 mm). Usable at high temperatures (from 1200°C up to 1400°C) having excellent resistance to thermal shock. Also available in ecological fibers.
