The difference between extruded board and polystyrene board
1. Different ingredients
The polystyrene board is made of expandable polystyrene beads containing a volatile liquid foaming agent, which is pre-heated and heated in a mold to form a white solid with a fine closed-cell structure.
Extruded board is made of polystyrene resin and other additives through extrusion process with continuous uniform surface layer and closed-cell honeycomb structure.
2. In terms of function
Extruded board has excellent thermal insulation properties, excellent high-strength compression resistance, high-quality water repellency, moisture resistance, light texture, convenient use, stability, good corrosion resistance, product environmental protection and other performance characteristics.
Polystyrene board has excellent thermal insulation performance; high-strength compressive performance; superior water resistance and moisture resistance; corrosion resistance and durability.
3. Usefulness
Polystyrene board is mainly used for the insulation layer of building walls, roof insulation, and composite insulation board; used as insulation material for vehicles, ship refrigeration equipment and cold storage; used for home decoration and carving various models; used as a waterproof layer The protective layer.
Extruded board is suitable for building roof insulation, steel structure roofing, building wall insulation, building ground moisturizing, square ground, ground frost heave control, central air conditioning ventilation ducts, airport runway insulation, high-speed railway subgrades, etc.
