Tunnel Kiln Ceramic Fiber Blanket High Temperature Fireproof Insulation Materials

1. Brief introduction

Ceramic Fiber Blanket is made of special aluminum silicate ceramic fiber filament through double-sided needling process. The fiber’s interweaving degree, delamination resistance, tensile strength and surface flatness are greatly improved after double-sided needing process. Besides, the fiber blanket does not contain any organic binder to ensure the ceramic fiber blanket has good manufacturability and stability under high temperature and low temperature.
