Thermosetting polystyrene board is cost-effective and has outstanding thermal insulation capabilities, especially in the case of low density. It can be clearly seen that it is more cost-effective than other fireproof external insulation systems under the same effect. It can not only make foam products of different densities and shapes, but also produce foam boards of various thicknesses.

Thermosetting polystyrene board has low strength and low shear strength. The board may be damaged not on the bonding surface, but directly in the middle of the board. The good strength performance of extruded board is more reassuring. The tensile strength of 0.1 MPa is equivalent to the tensile strength of 10 tons per square meter. After the thermosetting polystyrene board is placed for a period of time, a small amount of polyurethane foaming agent remaining in the foam board will be released to prevent the residual polyurethane foaming agent from becoming soft foam plastic. After aging, the foam board can be subjected to all physical treatments through thermosetting polystyrene board or thermoforming equipment.

Reducing the self-weight of buildings and improving the degree of assembly and prefabrication is one of the development trends of modern construction technology. The technical standards and product specifications mentioned in the content of thermosetting polystyrene board are mostly about the combustion performance indicators required for insulation materials. The thickness of the insulation material should comply with the relevant regulations of the wall design. The bonding between the thermosetting polystyrene board and other structural layers should be firm, the bonding strength and connection method should comply with the regulations, and the handover work should be done at the same time.

When choosing the thermosetting polystyrene board material for the exterior wall, you should understand whether the structure, quality and chemical properties of the material itself are stable. If the chemical properties of the material are unstable, problems will occur during the later use, so it is recommended that you must choose some materials with relatively stable chemical properties.
