German high-temperature thermal insulation gaskets are new types of environmentally friendly and high-temperature-resistant gaskets. They are composed of ceramic fibers and decomposable mineral fibers. They can withstand high temperatures (1100℃) and have very low thermal conductivity, making them an ideal insulation material. They are widely used in industries such as steel, oil refining, casting, chemical engineering, glass, mechanical manufacturing, oil and gas burners, industrial furnaces and boilers, furnace draft doors, fireproof doors, etc. They are available in three types of materials: ISO750 (750℃) and ISO1100 (1100℃).
