Refractory paper Grefseal BТО-1

Grefseal high-temperature refractory ceramic fiber is produced using a special technology that provides high mechanical strength, homogeneity of structure, flexibility, smooth surface, a large range of sizes with low thermal conductivity. Application: Heat-insulating pads, heat insulation in steel ladles, compensating temperature seams, thermal insulation in steel casting molds, insulation of induction furnaces, heat shields, electrical insulating linings, lining of crucibles, lining of molds for glass, fire protection.

Advantages: Flexibility and elasticity, low density, low thermal conductivity, accuracy of standard sizes, the possibility of obtaining die molds, easy installation and cutting, high tensile strength, resistance to thermal shock and heat changes.
