Extruded polystyrene (XPS) insulation board is a kind of rigid board which is made of polystyrene resin as the main raw material and continuously extruded and foamed by a special process. It has a unique and perfect closed-cell honeycomb structure, and this structure gives it excellent characteristics such as anti-high pressure, moisture-proof, impermeable, non-absorbent and corrosion-resistant. At the same time, its thermal conductivity is extremely low, which makes it an efficient thermal insulation material.
Firstly, the higher the closure rate of the extruded plastic board, the better its thermal insulation performance. Most of the insulation boards achieve the purpose of heat preservation through the special structure inside, while the extruded plastic board enhances its own adiabatic performance through the closed cell structure inside. Generally speaking, the higher the porosity, the better the insulation performance, and most of the extruded panels can reach more than 99% porosity. A vacuum layer is formed inside the material, which can effectively avoid the penetration and exchange of air. The closed cell ratio of the extruded plastic board is better than most of the thermal insulation materials, so the thermal insulation effect of 20mm thick extruded plastic board is equivalent to the thermal insulation effect of 120mm thick perlite.
Secondly, the application range of extruded plastic board is very wide. It is commonly used in the insulation work of building roofs, and the insulation work of various building walls. It can also be applied in plaza floors and ventilation ducts, and used as thermal insulation layer treatment on runways in airports. Extruded panels used in different places have different requirements for insulation performance, so the application range will also have a certain impact on the insulation performance of extruded panels.
Finally, the extruded plastic panels produced by different manufacturers in the use of raw materials and process there will be some subtle differences. These details in the production process will affect the insulation effect of the extrusion board. The double-drive extrusion process is used in the production process, which makes the thickness of both sides of the material uniform and the structure more stable and complex. The thermal conductivity of the extruded panels made using this method is only 0.028W/M.K, which is an excellent thermal insulation material that can be applied to the exterior walls of various buildings.
Overall, extruded polystyrene (XPS) insulation board is an efficient, high-quality and widely used building insulation material. Its closed-cell structure and excellent thermal insulation properties make it ideal for the construction industry. At the same time, extruded panels produced by different manufacturers will have some slight differences in the use of raw materials and process treatment, and these details will affect the insulation effect of extruded panels in the production process. Therefore, choosing extruded plastic panels produced by regular companies can ensure the stability of its quality and performance.
