High-temperature glass wool is a thermal insulation material that can resist high temperature with its lightweight, lasting durability and excellent thermal insulation property, the material that is made up of uniform and slender and elastic glass fibers as well as special high-temperature adhesive. The outer protective layer of thermal insulation structure can use galvanized iron sheet based on specific circumstances. Application of high-temperature glass wool: It is widely used in equipment and pipelines of electric power, petroleum, chemical industry, light industry, metallurgy and other industries, serving as the thermal insulation.
