Shandong extruded board is a new type of polymer material widely used in the fields of construction, transportation, environmental protection, etc. It is a plate-shaped material made of polystyrene as raw material, extruded by an extruder under high temperature and high pressure. Extruded board has the advantages of thermal insulation, waterproof and moisture-proof, pressure resistance, and light weight, and has become one of the indispensable materials in modern construction.

First of all, the thermal insulation effect of Shandong extruded board is very obvious. Its thermal conductivity is very low, and it also has good moisture-proof and heat-insulating properties, which can well reduce the transfer of heat, thereby ensuring the stability and suitability of indoor temperature. In today's energy conservation and energy consumption reduction, extruded board is widely used in the field of construction.

Secondly, Shandong extruded board also has good waterproof and moisture-proof properties. The density of extruded board is very small, and it has a closed-cell structure, which makes its water absorption very low and can well prevent the entry of moisture. Even in a humid environment, the performance of extruded board can remain stable and will not be affected by moisture, thus ensuring the life of the building.

In addition, Shandong extruded board also has good compressive resistance. Although the density of the extruded board is very small, its unique plate structure makes it very strong. Even under heavy loads, it can remain stable without deformation or breakage.

In general, Shandong extruded board is a high-performance, multifunctional, environmentally friendly new material with many superior properties. It has been widely used in modern buildings, especially in thermal insulation, and has become an indispensable building material. With the continuous development of science and technology and technology, it is believed that the application scope and performance of extruded boards will be further improved.
