Vermiculite coated fiberglass fabrics is mainly composed of alkali-free glass fiber and vermiculite, in which glass fiber is the substrate and vermiculite is the coating material. Vermiculite is a natural mineral. The vermiculite coating makes the composite glass fiber cloth resistant to high temperature in a short time to 1000C and continuous temperature resistance to 800C.In the production process, the vermiculite is uniformly coated on the fiberglass products, and then dried in the subsequent process, the vermiculite settles on the fiberglass products, so as to produce coated vermiculite glass of different thicknesses and specifications Fiber products. At the same time, the glass fiber cloth has stronger fire breakdown resistance and friction resistance, and good mechanical processing performance. UNITY vermiculite fiberglass fabric is also widely used in the fields of insulation cover, welding fire protection, high temperature filtration, high temperature sealing and so on.
