Product introduction of ceramic fiber blanket
The ceramic fiber blanket is white in color, with regular size, integrating fire resistance, heat insulation and thermal insulation functions, and does not contain any binding agent. Ceramic fiber blanket, also known as aluminum silicate fiber blanket, is called ceramic fiber blanket because one of its main components is aluminum oxide, which is the main component of porcelain.
Features of ceramic fiber blanket
Ceramic fiber blanket can maintain good tensile strength, toughness and fiber structure when used in neutral and oxidizing atmosphere. The product is not affected by oil turbidity, and its thermal and physical properties can be recovered after drying. Ceramic fiber blanket and fiber cotton have the same excellent chemical stability and higher strength at room temperature and after burning
