Ceramic fiber aluminum silicate refractory ceramic fiber fireproof insulation paper

Product Description Ceramic fiber paper takes high purity alumina silicate fiber as main raw material, using wet paper molding process to be made. The advance manufacturing technology makes the distribution of fiber be very even and the paper’s thickness and storage can also be controlled strictly, with excellent refractory and insulating effect. Ceramic fiber paper is completely free of asbestos, and is designed to be an economic replacement for asbestos paper in most applications.   Application 1. Industrial Insulating, Sealing and protecting materials. 2. Electric and thermal insulation materials for electric industry. 3. Insulation materials for instrument-equipment. 4. Insulating materials for motor industry. 5. Filling materials for expansion slot. 6. Insulating materials as the sinter resistant. 7. Sealing gasket for molten metal. 8. Fireproof materials.   Standard Specification Thickness: 0.5-6mm. Width: 610mm, 650mm, 1000mm, 1220mm. Density: 160kg/m3-200kg/m3. Temperature: 1260°C -1400°C. Packaging: In plastic bags and then in cartons (special packaging is available per requests). Can also produce various widths according to customer requirements.   Physical Properties
