Now with the increase of extruded plates in the market, the quality and role of Shijiazhuang extruded plates have also become our topic of concern. How to distinguish the extruded board, let's talk about it below.
Shijiazhuang extruded sheet is polystyrene foam, which is divided into two types: expandable EPS and continuous extruded XPS. Compared with EPS sheet, XPS board is the third-generation rigid foam insulation material. The complicated production process of EPS board has the superior performance that EPS board cannot replace.
This closed-cell structure insulation material can have different pressures (150-500Kpa) while having the same low thermal conductivity (only 0.028W / MK) and excellent long-term thermal insulation and compressive performance, compressive strength Up to 220-500Kpa
In various aspects, Shijiazhuang extruded board and foam board are very different.
Cost differences. Extruded polystyrene boards are generally more expensive than foam boards. At the same time, there is a certain gap in the production process of the two. The process of the extruded board is simple, but the strength of the extruded polystyrene board is higher than that of the foam board, and the extruded board is much better than the foam board in terms of thermal insulation performance.
Differences in characteristics. The strength of the extruded board is higher than that of the foam, and the flame retardant effect of the extruded board is more prominent. Compared with the extruded board, the flame retardancy of the foam board appears to be poor. Therefore, we can see that although both are more commonly used in energy-saving building materials, they are used as floor heating insulation materials. The performance of extruded board is far better than expandable polystyrene foam board.
