Glass fiber has been used most in the IT and construction industry. But for the high temperature insulation industry, the glass fiber is usually used in the temperature below 700℃ environment. As glass fiber’s cost is much less than ceramic fiber. And in some special environment, for example, the electrical environment needs better insulation from heat and electricity; the glass fiber now is more suitable.
The vermiculite is a natural, inorganic, non-toxic mineral. It could expand to several times under high temperature surroundings. The vermiculite’s thermal conductivity is small; it’s an excellent insulation material. Vermiculite could hold over 1100℃ high temperature.
Tianjin Tuolin Technology glass fiber cloth with vermiculite coating is a woven fabric made of E-glass fiber yarns or C-glass yarns. The vermiculite could expand under high temperature and fill in the gap of ceramic fibers. This will increase much more for the fabric on the insulation performance. So the glass fiber fabric with vermiculite coating is an excellent insulation cloth for high temperature.
The glass fiber cloth with vermiculite coating could be used in large area industrial thermal insulation, heat preservation, fireproof, protection and base cloth for fire curtain, welding curtain and coating cloth.
