Extruded Polystyrene Board

What Is Low Internal Stress Technology?

Low internal stress technology (SOHO core patent) is the use of multiple foaming equipment for multiple foaming of materials, so that fluorine-free, bromin-free low internal stress extrusion (XPS) extruded polystyrene board to achieve 100% perfect foaming,  its dimensional stability than the traditional extrusion board more than double, the closed-cell extruded polystyrene foam can be made. The technology to overcome the world decades of unsolved extrusion board dimensional stability aging instability problem, Deformation, cracking, falling off and other drawbacks will not be repeated.

Types of Extruded Polystyrene Board

XPS Insulation Board

XPS Insulation Board

XPS (Extruded Polystyrene) Insulation Boards are a high-performance insulation solution widely used in both residential and commercial construction. Known for their excellent thermal properties, moisture resistance, and structural strength, XPS boards are a preferred choice for various insulation applications.
Graphite XPS Insulation Board

Graphite XPS Insulation Board

Graphite XPS boards maintain the high compressive strength characteristic of XPS insulation, making them suitable for load-bearing applications such as under concrete slabs and in foundation walls.

Applications of Extruded Polystyrene Board

Extruded polystyrene boards are widely used in drywall insulation, flat concrete roofs and steel structure roof insulation, moisture-proof insulation on low-temperature storage floors, lower layers of low-temperature floor radiant heating pipes, parking platforms, airport runways, highways, etc., to control ground freezing. It is an inexpensive and high-quality thermal insulation and moisture-proof material for the construction industry.

Main application areas of extruded boards:

  • Extruded boards can be used for basic pavements, airport roads and highway basic pavements.

    It has the advantages of waterproofing, moisture-proof, corrosion-proof, and durability, and can effectively alleviate foundation collapse caused by road leakage;

  • Extruded polystyrene board is an indispensable material in cold storage construction. 

    It not only plays the role of heat insulation, but also can absorb and buffer a small amount of water vapor condensation, reducing the formation of water droplets due to the microporous structure of the extruded plate surface. The requirements for extruded boards for cold storage are high and the thickness is greater than 10cm. Therefore, in the construction of cold storage, two layers of extruded boards are usually used, one layer is to increase the thickness, and the other layer is to stagger and splice two layers of extruded boards to improve the thermal insulation performance and avoid temperature loss;

  • Extruded polystyrene boards can be used for thermal insulation of exterior walls and roofs. 

    Extruded polystyrene boards are lightweight and easy to use. Class B1 and B2 extruded polystyrene boards can avoid becoming combustible and causing major accidents in the event of a fire. They can also add heat to buildings. A layer of insulation to save energy. Extruded polystyrene boards are widely used in various fields due to their advantages such as heat insulation, waterproof, moisture-proof, light weight, and pressure resistance. In today's society, in order to pursue low carbon and environmental protection, extruded boards can be reused for exterior wall panels, and thermal insulation layers can be added to buildings to save energy.
