With the development of the domestic construction industry, the flame retardant performance of the exterior wall thermal insulation extruded board for building has attracted more and more attention. In the past few years, several large buildings have been burned, and the fire resistance of building materials has been deeply concerned. Extruded boards can provide thermal insulation for buildings, energy conservation and environmental protection, but their own flammability is a headache. There is no perfect thing in the event, and there must be something unsatisfactory about the superior effect. Xps extrusion board is made of polystyrene as the main raw material by extrusion at high temperature with additives. It has a continuous and uniform closed cell structure, and the wall of each dimension is consistent

Thermal insulation board, as its name implies, is a board like material with thermal insulation performance. Here, it usually refers to the thermal insulation materials used on buildings. As long as they can provide thermal insulation for buildings, they are all thermal insulation boards. Such materials are compared, such as extruded board, polystyrene board, rock wool board, composite rock wool board, polyurethane board, phenolic board, glass wool board, rubber board, etc. Among these kinds of boards, xps extruded board and polystyrene board are often compared with each other, because these two boards are produced from the same raw material, and different production processes form different insulation boards after comparison. Compared with other plates listed above, the material is completely different
